Today i tell you with my decades of experience as an onion farmer: the problem is not in the summer, all in the last ten days of the frost
Outgrowers tend to be long ahead, and onions only come from within。
The temperature rises around the night and day before and after the fall of the frost, and is the only golden period during which the onion lasts to sow, store its nutrients and enrich its onions. These ten days of management are in place, day by day, day by day, hard by day, and once you're lazy, you've made a mistake, you've got a long run ahead of you, and you'll end up empty and you'll lose the price
First, let's get to the point: why is it that onions are the easiest to soften up after frost
Many farmers have mistakenly assumed that onions mature when they grow high enough, and that they are left out in the later stages, waiting for the frost to cool down。
It's the biggest, deadliest mistake
We explain the growth patterns of the onions with the truth that farmers understand:
Autumn to the cold: leaves, heights, trees
During that time, he tried so hard to grow leaves, to pull up a tree, to look at the plume, but only to grow a “stand”, which was empty, loose inside and did not accumulate dry matter at all。
2. Frozen to frost down: onions stop growing high and start squeezing
The greatest features of frostfalls are warm day, cold night and very poor temperature。
At this point, the onions are no longer new leaves, no taller leaves, and all of the nutrients saved by the luminous co-operation of the leaves are deposited back into the onion, filled with blanks, hardened tissues, heavy weights, as the old onion farmers call it “grass”。
Three, when the frost drops, let it go. It's the root cause
In the last 10 days, when there is a shortage of water, a shortage of fat, no soil, no leaves for the sick, the nutrient transmission is interrupted, the intestines are filled with displeasure, and the final harvest is empty, soft, heartless and no weight。
In conclusion, it was the "empty shelf" that was long before, and it was the "real output" that was poured down by the frost for 10 days
Ii. Key number one: frostfall control. 90% of farmers are watered wrongly and empty
In the latter days, the biggest culprits were the indiscriminate watering, the flooding, and the drying and wetting。
A lot of old people think that the higher the onions, the more water they water, the bigger the water, the bigger the water, the worse it is
I'm gonna water it right
1. No flooding
After the fall of the frost, the onion roots grow slowly and the capacity to absorb water decreases. The water is flooded, the soil is oxygen-deficit, the roots are not breathing well, nutrient transmission is obstructed, onions are interrupted and the hollows are softened。
2. Keep the soil wet and dry wet
The surface is white and the earth is two or three centimeters dry, with little water, gliding and watering。
The soil is wet, roots are stable, nutrients continue to flow back, and white is slowly enriched。
3. Frozen water before cooling and less water after cooling
Before cold air and frost cooling, fresh water was poured early to keep the ground warm, to protect the roots and to prevent frost。
After the cold has passed, and in the cold days, the firm determination is not to water the water, the more empty and the worse the leaves。
The focus of watering the pits
Don't let it go
A little drying, a little slower at the top; once the water is strewn, there's a 100% loss of productivity。
Iii. Second key: frost-reducing fertilizer! Control of nitrogen-added potassium, special anti-aircraft cores, tightening
Many farmers have two extremes:
Either they are completely non-fertilized, and they lose weight and lose air
Or we'll have the same urea as summer, with only false leaves。
The frosting of onions is absolutely forbidden
The urea, high nitrogen fats only grow wildly new leaves, consume large amounts of nutrients and drain the onion's internal nutrients, making them emptier and softer。
Gold-and-fertilizer schemes for onion farmers (for frost-down slurry only)
Nitrogen, phosphorus, potassium
Potassium fat is the key to being solid, thick and heavy
The only effect of the frosting of potassium fertilizer is to accelerate the return of leaves, rapidly fill the white void, harden the onions, increase the weight, and make the flimsy soft。
Practice (zero difficulty for farmers)
1. Land blocks with weak long, yellow leaves and defertilized leaves: small quantities of high-heavy potassium fertilizer, thinly applied, once in 7-10 days, to stop only twice
2. Large and green plots of leaves: complete cessation of nitrogen fattening and the filling of only trace amounts of potassium fat, prevention of corruption and prevention of hollowness
Three, no urea, no nitrous compound fat, it's lateral
Core logic of fertilization
The frosting does not require long leaves, but only good faith。
The leaves are useless, full of whiteness, weighting, tightness。
Iv. #3 key: last time it's fine, it's fine and tight
It's an old saying: three, seven, last earth price。
A lot of farmers are working fast in the first place and feel close to the harvest when it comes to frostfalls, they are lazy and they lose。
The frosting of this ground, unlike in the previous period, is the last step of a stereotyped, thicker, whiter, anti-aircraft
It's the right part to practice
1. Must wait for the leaves to dry and retrain. Land
Leaned soil, wet earth-covered leaves are highly likely to cause frosting, purple plaster, and the leaves break their nutrients and must be empty。
Two, nothing but white, nothing
It's a thousand years of iron law
Buried with onion cores, directly rotting hearts, rotten leaves, stopped growing, and the whole onion died。
Peasant heights cover the naked parts of the onion, protecting the dry, white and warm roots。
Three, it's small, solid, no big earth
Large hard-eared leaves and onions, which affect nutrient transmission, can easily create local hollows。
Four. One to two times before and after frostfall. Land
It's not hard, it's hard, it's soft, it's warm, it's light, it's white, it's tight and it's thicker。
Peasant
Onions of light are protected against onions, temperature protection against frost, stationary plant protection against voltage and promotion of nutrient deposition。
A lot of good onions are long, white and tight, all on the last earth
Fifth, fourth key: protecting the leaves. Leaves don't suck
Many farmers have the biggest oversight: the harvest is near, the pests and diseases are fine, the leaves are bad。
It's a big mistake! The leaf is the onion processing plant
If the leaves are green and the leaves are intact, they can be continuously nourished and nourished
Once a leaf is sick and yellow, leaves are lost, factories are shut down, and direct irrigation fails, 100 percent empty hearts。
In the post-frost phase, emphasis is placed on two diseases and two insects:
Diseases: purple, frost
The onset of the two diseases was peaked when the frosting of the day and the night was characterized by high temperatures and early dew。
In the event of infection, the leaves are yellow, dry, perforated, rapidly and early decompression。
Pests: ostrich, leaf flies
The latter are the most vulnerable to neglect, eating leaves and destroying their veins, leading to greening and premature decay of leaves。
Principles of care
In the latter stages, the use of drugs is not blind, they are not abusive, they are slightly preventive, they are detected early in the day, and they preserve the functional green leaf, which is the yield。
As long as the green leaves stand up before the harvest, it'll be full of dust
Vi. The quintessential five: tight and frost-proof dry colds to prevent onions from falling early
After the fall of the frost, the cold air is high, the dry wind is high, and the temperature is extremely low day and night。
Suddenly, the frost and cold wind drain the onions, which are forced to stop growing early, to fail early, to fill their nutrients with onions, and to soften large areas of space。
The old farmer's cool trick
1. Stable water prior to the arrival of cold air, wetting of roots and steady temperature
2. To guard the root of the earth, which is not frozen and the whole onion does not fail
3. In cold, dry weather, proper water can be sprayed and wet to prevent the drying and premature decay of leaves。
Seven, four core error areas of the year
Zone 1: good forward, good forward, good forward
Correct: onion production is not up ahead, and the last 10 days of the fall of the frost have been soaked。
We're in the middle of a heavy water surge
Corrected: post-drive roots, nutrient disruptions, foil of the heart。
Zone 3: the frostfall continues to urea, the longer it grows
Correct: nitrogen fats dry onions, long leaves consume nutrients, onions must be empty, soft and light。
Wrong area 4: near harvest, untreated leaves
Corrected: yellow leaf rotting leaves stopped nutrients, slurries stopped, and much of the year was wasted。
Why is your house so tight and empty? The real difference is here
Ordinary farmers: only summer seedlings, frost drops and slacks, watch high onions, and empty and cheap selling。
Old growers: renouncing high-rises, targeting hard-core, water control, nitrogen control, potassium production, soil extraction, leaf preservation, for a dozen days。
The same acre
It's not going to work: there's plenty of empty onions, more than 30% reduction in production and the lowest purchase price
Managed: long, tight and full, full of scales, high prices for refined goods。
The last gap between the onions is in the frost for the last 10 days
Ix. Conclusion advantage
Grow big onions. Don't let the pre-surges confuse you。
High onions are not equal to high yields, green leaves are not equal to high prices。
Those who really decide on production, on the price to be sold, on the basis of the facts, and on the basis of the scales, only the slurry period of 10 days before and after the fall of the frost is set。
Water and water control, nitrogen-dumping potassium, precision earth-breeding, leaf protection against disease and cold seedlings, five steps in place, with no additional investment of one cent and a direct upgrade of the onion quality。
I'd rather have a front-stage catheter. Don't turn back
Old man with big onions, did your family look tall and pull out empty cores? We have to keep up with the frost landing line this year
I think this old farm-worked piece is really working
