When to plant leeks and when to plant them?

Generally speaking, soil can be sown between thawing and autumnal equinox. Most areas are mainly planted in spring, and the local surface temperature can be stabilized at about 5 ~ 10 degrees. The spring sowing time of leek in Huanghuai Valley is from early April to mid-April, 65438+February to February in the south and May to June in the north. The sowing method is drill sowing, and the plastic film is covered immediately after sowing, and the plastic film is removed when a large number of seedlings are covered with soil. Before and after sowing in beginning of autumn, the sowing amount was twice as much as that in spring, and the management was mainly wet and dry. Attention should be paid to weed control in the management of autumn-sown leeks. Summer sowing leeks should not be covered with too thick soil, and only by keeping the soil moist can the seedlings emerge smoothly.

1. temperature

Leek is a cold-resistant and heat-resistant vegetable variety, and likes a cooler environment. The suitable temperature for seed germination is above 65438 02℃.

lamplight

Leek has strong shade tolerance and weak light, which will lead to low yield. Too strong light will lead to poor quality. Medium intensity light is the most suitable.

Step 3: Moisture

The relative humidity of the air can be kept at 60% to 70%.

4. Land

The ph value of soil for planting leek is 5.5 to 6.5, and leek needs a lot of fertilizer.
