WhiteOnion: don't die waiting for the white
Onions don't have to sow seeds in the day. The most comfortable seeding is 15-22°c, and the ideal pre-winter seedlings are 2-3 real leaves, 10-15 cm tall. It's too early to plant, and it's grown into a little chubby chubby chubby. It's a low-temperature spring. It's too late to plant a leaf or two, and the roots are not steady, and the frost is all gone。
A rough timetable: north-east/nemmon was cold early in august — early in september; north china, shanxi, hebei, shandong, henan, white lun and around until mid-september; the yangtze area was in mid-september; and south china was in october-november. The judgmental method: the average temperature drops up or down to 20°c over the next few days, not above 25°c。
The technology is not complicated: the choice of a well-drained sandy border, other onions and onions, and the use of decomposition to decomposed farmers to burn their roots. It's a shallow ditch, 1 to 1. 5 centimeters of ground, low seed power and thickness. 20 centimetres in rows, seedlings after seedlings, approximately 5 centimetres. Nitrogen control, rooting, freezing water once before freezing, like onions。
Garlic: don't listen."It's cold"to mobilize."
Autumn grill core temperatures: the best growing 12-16°c after seedlings, with seedlings showing average temperatures of around 17°c and 5 centimetres at about 18°c. In late september — early october — in large areas, the membrane could be extended until 5-10 october; in northern china, it is often said that the cold is near, but in the harsh north-east, it is high-risk and often rebuffed。
It is early: before the winter, the seedlings are too strong, nutrients are consumed twice, and in the next year, the petals, sole head, and early strangulation. It's late: there are only two green leaves left, weak, frozen, and dying in winter。
Operators:
Garlic graft, one to two days of tan, pick up the rotting petals; keep a part of the skin clean. Point-up, bow-backed, line-ranged by target — garlic/ garlic is usually 20 to 22 centimetres and 8 to 10 centimetres; only garlic is more intense. 3-4 centimetres of land, "deep snack" don't turn upside down, too light-freeze root, too deep sprouts. Obesity of decomposed organic fertilizer + potassium phosphorus is associated with garlic; in the case of the membrane, the acupuncture is detached. The winter water before the freeze can be poured coldly in the north to cover the straw and keep the south warm。
A word to hide from the pit
And i'm afraid of "morning and getting weak" and "morning and freezing." if you don't look at the yellow calendar, you'll have thin ground, you'll have to be fatter, and you won't have to go after nitrogen before winter. It'll be 100 times more useful than you do when you're crouching. Next year, you'll have no tears
