Old farmers who have grown potatoes in the fall, they've probably been beaten and beaten
After the fall, the weather cools a little bit, and many of the country's inhabitants rush to clean up their fields and plant potatoes in order to grow early seedlings, harvest early and sell more money. The idea is one thing: the land is planted to increase production and revenue。
But the reality is so full of face. A lot of farmers are working for half a month on the ground, fertilizing, selecting, planting, and doing the whole process carefully, and in the end they are either slow or mixed, more serious, straight-breeding, rotten potatoes, a whole piece of land that is bare and invisible。
Worked, seeds, fertilizers, man-made work, and lastly, no grain, nothing。
Many people have been unable to understand the reason, and have always felt that seeds are bad, fertilizers are bad, and even suspected of land problems. In fact, most of the autumn potato spears, the autumn spears, and the dead threads are too early
Autumn potatoes and spring potatoes are purely two planting logics, with spring potatoes growing early and autumn potatoes having to grow late。
I can't catch the exact time of planting, all the management skills are wasted, and today i'm telling the folks the core of the potato growing. I've been doing this all by myself, and i'm not saying anything, i'm not fooling around
Why can't autumn potatoes grow early? The sooner we grow, the worse
In rural areas, we grow in the light of the weather, and in the light of the weather, the best fear of the autumn potato is the high temperature of the “autumn tiger”, which is the biggest difference from the spring potato。
The spring is a gradual recovery in temperature, which warms and sows early, allowing potatoes to grow slowly, take root and grow better. In autumn, however, the temperature gradually declined, and during the early autumn period the temperature remained high during the day, even more so in the cold。
Many of the old people watch it cool, think they can grow potatoes, not knowing how warm the earth is, are the key to their survival
One, hot, straight-on-the-breed
Potatoes are sprouting, and its best bud temperature is between 15 and 22 degrees c。
If, at the time of planting, the temperature of the earth continued to exceed 25°c and the potatoes were buried in the soil, there would be no seeding. High-temperature and hot soil environments, such as steamy bollards, can directly damage the seeding of potatoes. In a matter of days, the seeding of potatoes will be soft, moldy, rotting and then rotting directly in the soil。
It looks like it's flat, and it looks like it's all turned into mud, and there's no shadow of seed。
It's hard to get a seedling. It's hot and cold
Some of the strong-resisting seedlings of potatoes have survived at high temperatures, but have followed very poorly。
In high-temperature weather, the seedlings of potatoes are extremely poorly developed, have shallow roots and weak roots and cannot absorb moisture and nutrients. During the day, when the sun shines, the leaves fall, roll, roll, and grow, that is, what our farmers often call “fast seed”。
After that, even when the temperature cools and rains, the seedlings are not growing, with small plants, little potatoes, small potatoes, and no production at all。
3. Early-plant pest outbreaks, difficult to manage
High temperature and humidity in the early autumn are the most active stages of disease and pests。
Early-planted autumn potatoes are highly susceptible to late disease, early disease, rota disease, and tigers, platinum, golden needle worms and seedlings。
High temperatures, high humidity and the rapid spread of the disease are such that it will become a dead seed in a few days, that the drugs will not keep pace with the spread of the disease, and that they will end up in ruins and waste considerable time, agricultural resources and labour。
So remember the old saying: autumn potatoes are 10 days late, not one day earlier。
Remember the best seeding time! It's national, it's accurate
Many of the country's countryside see only the calendar, not the temperature, which is the greatest area of error. The north-south climate is wide, the date of unification is not accurate, the ground is warm and the temperature is 100 times greater than the day
To sum up a set of criteria to be used by farmers throughout the country to sow potatoes
Core seeding criteria (priority)
For three consecutive days, the maximum temperature during the day was stable below 28°c, at about 18°c at night, and the soil temperature fell below 22°c, the best planting window for the autumn potatoes。
As long as the temperature doesn't come down, no matter the number, no matter the temper, no matter how strong
Sub-regional precision planting time
1 south region (huanan, hubei, jiangxi, sichuan, chongqing, guangxi, guangdong)
These areas have long autumn tigers, slow temperatures, optimal planting time: late september-early october
In the end of august and the beginning of september, no seeding! At this time, the temperature is very high, and the seeds are so bad that they are barely seeded. Wait till late september, when the autumn wind cools, the temperature returns and the whole seedlings are planted again。
2 centralwon region (henan, shandong, hebei, anhui, northern jiangsu)
Four seasons are clear, and in the middle of autumn, the best planting time: mid-september-late september
Avoiding the high-temperature weather in early september, the heat remained high in the first half of the month, the risk of scavenging species was extremely high, the temperature was suitable after mid-late, and it was fast and strong。
3 northern region (sunxie, shaanxi, liaoning, jilin, inner mongolia, xinjiang)
Temperature and frost come early in the north, not too late to plant
Note that we are moderate early seeders, not high-temperature predators, and avoid the end of the three volts of august, when the temperature falls and sows immediately, preventing the frost-freeze of the chips。
One sentence at the core (recommended collection)
At the end of september, the southern autumn was the most secure of september; the northern autumn was fast growing and the heat was high
As long as this species is strictly followed, there will be little problem of sapling, lack of seedlings and lack of seedlings, with a rate of over 90 per cent。
The first four critical preparations to sow potatoes in the fall, avoiding the eavesdropping of most farmers
The choice of timing is only the basis, and preparation before seeding is essential if it is to be small, strong and productive. Many farmers are replanting, not pre-treatment, with long and low yields, all of which were not done before
1. Choosing potatoes: determined elimination of bad potatoes, weak potatoes
Potatoes are fundamental. Seeds can't be managed。
- priority: medium-sized potatoes of equal size, smooth skin, full budding, non-destructive, non-stereogenic and insect-free
- throwing away: soft, moldy, decorated, frozen, worm-holed seeded potatoes. Don't feel bad. They spread the whole land with disease, resulting in large areas of scab。
2. Sterilization of seed seed seed: elimination of the disease
The high temperature of the autumn potatoes, the ease with which the potatoes are grown, and the need to sterilize the seed before sowing are key points that many farmers have neglected
Three days before the seeding, the seeding of potatoes was spread in the cool air, avoiding the sunlight and naturally giving rise to short sprouting。
If you grow larger potatoes, you have to cut pieces, remember: the blades have to be disinfected with alcohol or water
Each piece is cut, the tan is laid, the wound is dried up and must not be soaked as to be highly contagious with the fungus。
3 - the whole rise: autumn potatoes are the worst afraid of drying up. Root
Autumn potatoes grow all the way to the autumn rainy season, with high temperatures and water, and a rotten potato。
The whole area must therefore rise up to about 20 centimetres high, deep and straight, and ensure rapid drainage after rain, with no water and no roots。
The soil must be deep-spreaded, with no large earth creeps, so as to avoid the emptiness of the potatoes, the lack of access to the soil and the resulting lack of seedlings and weak seedlings。
4 bottom fertilisation: obsessive fat
It's a big mistake for many of the old people to sow one-off fertilizer, undefeated farm fat
In the autumn, high temperatures and fermentation in the soil lead to direct burning of seeds and roots, resulting in dead seedlings。
Bottom fertilizer is preferred to a well-corrupted farm + balanced compound, evenly distributed into the soil, fully mixed with the soil, and no direct exposure of the fertilizer to the seeding of potatoes。
Autumn potato field practice techniques, small and strong, and late fortuitous
Timing, clean-up, seed processing and poor seeding methods are still problematic, and these steps of practical exercise are lessons learned by old farmers over the years。
Depth of seeding: lightness and deepness
Spring potatoes can grow in the right depth. Autumn potatoes have to be shallow
High-temperature weather increases the temperature of the earth's layer, and the air is less permeable。
Best seed depth: 8-10 cm
The sowing is too deep, the soil is sorely hot, and the potato is oxidized; the sowing is too shallow to run and dry the seedlings, and 8-10 centimeters are gold depths。
2. Solution density: reasonably dense, non-crypted
Autumn potatoes grow with shorter and smaller growth cycles than spring potatoes and are moderately dense。
The length of the line is 40 and 25 centimetres, with approximately 4,000 units per acre, with good ventilation, long, non-compression, even and full-sized potatoes。
3. Land cover wetting: small earth cover and seeding
The seeding must be covered with concrete soil and not with large hard earth。
When the seeding is completed, the soil is slowly torn and soil moisture is preserved. Autumn is most afraid of dry seeding, the soil is dry and water is scarce, the seeding of potatoes is unable to grow, the yield of seedlings is delayed and poorly grown。
In the event of a drought following sowing, small water can be slowly poured over once, heavy water is prohibited, and the stifling of water is bound to rot。
Six of the most easy pits for the potatoes in the autumn
In combination with the widespread diseases that farmers grow each year, six fatal faults have been created, so that, as long as these problems are avoided, the autumn potatoes are still stable
Zone one: the heat sows early and robs the city
Many farmers want to sell their potatoes early at high prices and deliberately sow them. As a result, high-temperature scavenging seeds are not only not pre-cooked, but also delay the optimal planting period, with no cost。
Mistake two: no sterilizing, no drying of chips
The cuts go down directly, the wounds are exposed to soil bacteria, the high temperature, the wet environment is rapidly infected, the saplings are depleted and re-sowning is costly and laborious。
Mistake iii: application of raw chicken dung, goat dung, cow dung
Fermented fermented roots are burned, the seedlings die yellowly, with late potato malformations, hollows and extremely poor quality。
Mistake iv: water pouring, no drainage after rain
Autumn potatoes are not afraid of drought, water is the number one killer of rotten potatoes, and after half a day of rain, it causes widespread disease and death。
Zone five: too deep and too thick to sow
The depths of the earth are characterized by high temperatures and poor air penetration, a lack of oxygen for the seeding of potatoes and a significant reduction in seeding rates。
Mistake vi: neglect of pests and diseases in the nursery age
In the early autumn, the fungus of pest disease is active, no early prevention after seeding, late disease and the outbreak of tigers, and light seedlings are eaten in a few days。
Autumn potato management center, 3 o'clock, double production
The seedlings were not managed in a complex manner, and three points were caught, the potatoes were much thick, large, smooth and productive。
1 - shrimp control
The seedlings grow to about 10 centimetres in time to pine, break the slabs of the soil, increase the aerobicity of the soil, promote deep roots, breed strong seedlings and avoid weakness。
2nd bouquet of fertilizing potatoes
Potato blooms and enters a critical period of masturbation at which potassium fat can be adequately replenished and nitrogen fat can be less applied. Potassium fertilizer contributes to the expansion of the chips, allowing the potatoes to grow evenly and rapidly, and to increase production effectively。
3. Early prevention of disease and insects
The main focus of the nursery and potato season is on the prevention of late disease, early disease, frost disease, regular visits to the fields, and timely prevention and treatment of small diseases, which are less costly and less costly than treatment。
I'm sorry
Autumn potatoes are grown, timing is the top secret, precision management is the second guarantee。
Never again, with old experience and a sense of early seeding, a tiger's high temperature is the natural enemy of autumn potatoes. As long as the optimal planting window is secured, soybean sterilisation, uplifting, fertilizing science, rational sowing can be achieved with a full seedling, a strong potato and a steady high yield
