Owing to the coldness of the potatoes in the autumn, it has been born for only 80-110 days over a long period of time, with a very low tolerance for errors in seeding. We've had early exposure to the high temperature of the tigers of the fall, and we've grown sour potatoes, but the frost has arrived early, so the chips are too big to be small. The capture of the golden seeding window in various locations must be accompanied by a four-step core management in order to produce a well-corresponded, soaked and productive product。
I. Timetable for gold planting in the national subdistricts (in the absence of pits)
- hwang hwai, hwang hwai (sweet, subei) - mid-august - end of august, best summer before and after, avoiding continued high temperatures
- the yangtze river basin (two lakes, zhejiang, kawasu): in late august-early september, when the tigers retreated to replant the plant
- south china's two wide, fujian: late september, slow down, delayed planting to avoid high temperatures
- north-east, nemong typhoid areas: open autumn is not recommended, life is chronically inadequate and freezing is not possible
Hard-core criteria: 10 centimetres of temperature are stable below 25°c to sow seeding and root causes are eliminated。
Ii. First step: planting potato sprouts and eliminating hibernation
Autumn potatoes are mostly kept in spring and are dormant, with slow and high rates of decay。
Operation: a cold ventilated area, wet sand-covered sprouts, temperature around 20°c, with a bud of 0. 5-1 cm short sprouting best; cut-off blocks with one to two buds per piece, with a knife sterilized, cut-in to dry-drive grass-wood ashcreas and significantly reduce the risk of bad seed。
Iii. Step two: high and low, waterproof sprouts
Autumn potatoes are the most afraid of water accumulation, and low-lying areas must rise up (20 cm high) and drain。
The sowing depth is 5-8 cm, shallower than the spring potatoes, avoiding high temperatures and sprouts; it is based on the use of high-strength double-walks with a distance of 40 cm and a range of 20-22 cm, which are reasonably implanted and are increased by group production。
Step three: planting in the evening, cooling and wetting
Avoid high noon temperatures and choose to sow in the dark or in the evening; it can then cover straw and sunnets, reduce the temperature, keep the soil moist, release the seed in time and prevent the longing。
V. Step iv: precision management of water fattening and the expansion of potatoes
Re-fertilizing, decomposed farmers + potassium sulphate compound fertilizers; applying thin nitrogen fertilizers after cyanide seedlings, and re-eating potassium fertilizers during the current period to promote the expansion of the chips; growing small and long-term water effort, immediately draining water after rain, and eliminating the use of water in the fields to cause rotten potatoes。
An old farmer shelter
Autumn potatoes sow to see the temperature, and sprout the dryer root。
It's soaked in the evenings, and potassium is so fat that the chips are sunk。
Early runoff and frost-freeze, full of potatoes。
Autumn potato cultivation, time at the core, management is the key. In the north and south, seedlings, pick-ups, water control and fattening can be used to avoid bad seeds and small potato problems。
