Snow's just passed. Is your land still deserted? Some people have quietly earned the first barrel of gold by growing peas。
When most people think it's "cool winters," they use the 60-day climate window layout. Peas, this underestimated cold-resistant crop, is playing a “war against seasonal wealth” in the north and south. The northerners rely on the sheds to achieve “freedom to grow at under 5°c”, while the southerners concentrate their winter fields on open cover, while the core differences are hidden in 5°c temperature, 3 cm seed depth and 1 layer of straw cover. Today, we break open and say, "snow to big snow peas, is it the pit or the wind?"
One, five degrees below zero can grow peas
Peas are not a "frozen seed," but a "fat survival master." its seeds start at 5°c, and its seedlings can carry a 3°c short-term frost, but they can never live in ice. The northerners are impulsive: the north of china fell at 0°c in the aftermath of the small snow, and the open seeding was tantamount to “freezing money”, but keeping the interior of the shed at more than 5°c, which can be collected for 70 days by a “freeze-resistant force” such as mae 6 and liao pai 1, which is more than 40 days from the spring planting morning in the city, with the difference doubling directly。
The southerners don't care: the temperatures of 5-12°c in the yangtze river basin seem friendly, but a sudden “crawling down” can wipe out the young people. The lessons learned from the blood of rural households in guizhou on the occasion of the peak festival are evidence of the fact that high-altitude areas have less than a membrane cover, with a high rate of 60 per cent of freezing injuries, while hunan changde's old style of double-insured “diplomatic + membrane” has stabilized at over 95 per cent. Remember, peas' cold tolerance is a “lower limit”, not a “ceiling limit”, and if they want to make money, they carve the “temperature red line” in their head。
Ii. North-south pk: the same peas, who earns 30,000 more
North plant cultivation: spelling techniques, more detail. The greenhouse shed is not a “one-size-fits-all safe”, and the temperature is high and the roots are wet. Peking tunzhou growers found the three temperature controls: 10-15°c pre-plant growth, 8-12°c pre-planting, and no less than 5°c at night - this combination of punches makes his peas strong and half sick. The newbies who chose the wrong varieties, blind and windy “sweet peas”, ended up in the shed getting wet over the tip of the ground, at a loss of $2,000 per acre。
Southern field planting: winning in “slazy management” and losing in “yes”. The farmers of the yangtze river recognized the zhuang 1 and sou mae 3, who were able to slow down after spring at 5°c. But there are people who are smart: either sowing too deep (over 5 cm) leads to “silent sprouts”, or watering too hard leads to roots of decay. Old lee, jiangxi, has calculated a sum: the correct membrane plus dry wet water, 800 pounds more acre than “grain management”, $2,400 per acre at 3 yuan per pound, and 72 million more 30 acres。
Iii. 60 days of secret collection: 80% of success in the selection of varieties
No more superstitious “net red varieties” and anti-frozen + early ripening is the hard thing. The northern facility's preferred “max 8” is: 6°c cold, with 65 days of fresh thawing, and avoids the hot and wetness of the spring shed; the southern field locks down “kawape 6”: the first wave of anti-powder disease, slow winter growth, and 10 days faster than normal. Caution: the late-cooked varieties that are packaged as “high-yielding” are the pits that grow in winter — longer than 90 days of life, flowering before the winter is over and half of the twilight is lost。
Seed pre-treatment is "hidden plus subdivisions". Real data from hubei agricultural station show that 25°c hot water is impregnated for four hours + polybacteria, which is 20% higher than the rate of live seeding of dry seeds and a 30% reduction in the disease during the nursery season. But there's always someone who's trying to save it, and it's so good that you've lost 500 pounds。
Four, three centimetres of sowing depth + one layer of stench: these are the smart ones
Seeding is not a “deep pit seed”, and it is a deep decision to live or die. The northern sheds are low-temperature, with seeds buried at a depth of 4-5 cm and using the soil to keep them warm; the adhesive land of the south is soaked at 3 cm to prevent rotten seed. The farmers of jiangsu salt city invented “finger measurement”: the first section of the index finger is soiled at a depth of just 3 cm to the finger section, with a simple rough but 100 per cent accuracy。
The straw cover is "free temperature protection". South unrecovered? A 5-centimetre-heavy rice straw with a temperature of 2°c and protection against weeds. In hunanyong state, the incidence of freezing death among young seedlings is only 5 per cent, with no coverage up to 30 per cent. Remember: the straw should be covered in the line, so don't be sore, otherwise the temperature will change to "silent."。
Five, don't wait for the frostbite! These three are early. Look
The leaf is red. It's called a distress signal. Peas seedlings are suddenly red, either in water or as a precursor to the freezing, so they spray 0. 3 per cent of potassium phosphate + ethethrin, which can slow down in two days. Dip-dip-dip-dip-dip-dip-dip. Pyramid + root agent for rooting, three days once and two times, saving 80% of the seedling. There are two things to do after snowfall: clear snow + drain. Every year, there is snow in the northern sheds, and after 24 hours of snow in the south melts, the roots of the system rot。
Snow growing peas, not luck, is probability. The northerners calculate the temperature of the interior and the maturity of the species, the southerners calculate the frequency of frost and the cost of coverage, while those who are blind and managed by feeling are destined to be ash “anti-season planting”. Remember: there is no "leave-in-the-leave" in agriculture, only a "win" — a pea field for temperature, varieties, measures, in the cold of the winter, is your spring cash machine。
It is not too late to do so: 10 days to sow in the sheds in the north and 15 days to the surface of the south. Your place, ready
