First, the sowing date. It should be broadcast in due course. The plain area is generally sown in late January and early February. The mountains are sown after thawing on the ground, generally from late March to early April. Second, sowing method Ridge ridden directly after the ridge to be sown. If the soil before sowing is dry and there is not enough soil at the end of the planting season, we must first spring irrigation and weeds must not be sown. Two rows per ridge, planted in a ridge. It is forbidden to plant on ridges or even on ridge slopes. Ditching, ridging, seeding, and filming are completed once, and care must be taken not to sow deep enough to prevent emergence difficulties. Third, the planting density. Should be closely planted. Ridge spacing 30cm ~ 40cm, plant spacing 25cm ~ 30cm, sowing depth 5cm ~ 8cm. Generally used for every 667m2 seed amount 100kg ~ 150kg. After sowing, the soil is covered with flat ridges and covered with membranes. Fourth, correct film. Choose 0.005mm ~ 0.006mm thick, 80cm ~ 100cm wide mulch. For every 667m2 of plastic film 3kg ~ 4kg. When the film is covered, it is ditched on both sides of the ridge. Spread the film horizontally and horizontally so that the film is in close contact with the ridge surface. Simultaneously compact the two sides with fine soil and press it into the soil at a depth of 5cm-8cm. Press some crushed soil every 1m on the ridge. In order to prevent the wind from blowing the film and blowing away, the film will really increase the temperature and protect the weeds.
