　　 1. Selecting good breeding seedlings: screening resistant varieties; using trays or nutrient mash to batch-produce seedlings in a timely manner, can be broadcast live, or spread in 2 leaves and 1 heart when planted in a tray or nutrient . It is recommended that very early-maturing cultivation be carried out in late October, and a large number of early-maturing cultivations should be warmed by the geothermal line in late January, and the nutrient soil should be disinfected to prevent pests and diseases.
2, Daejeon site should be applied to the base fertilizer and good car: after applying 100-150 kg of quicklime (once a year), the whole soil is deep, the soil is 10-20 days in the summer season or the frozen soil in winter; the organic fertilizer is 800-mu. 1200 kg or more than 2000 kg of fermented organic fertilizer plus high-quality ternary compound fertilizer 200 kg after the rotation of the soil after the whole box; requires the car to be straight and slightly turtle back, the depth of the trench is more than 20 cm, the length of the car is more than 50 meters Open the waist groove, the drainage of the three ditch is smooth, and keeping the soil cool and breathable is the key measure to control the dead plants.
3. Cover the mulch film in time. In the early spring cultivation, it is necessary to cover the film before the Spring Festival. It is best to use a 1 wire thick linear film or a 1.4 wire thick silver black double film. Spraying pre-emergent herbicides such as Jinduer or acetochlor when the lyrics (soil moisture) are suitable, and spraying the weeds after the growth of weeds (the granules such as phoxim should be applied to the ground with pests) Cover the mulch film in time, the mulch film should be tightly covered and covered with the surface of the car, and the surrounding area should be sealed with soil.
4. Take medicine with fertilizer when transplanting. It is best to use oxalicin or diclosan to soak the seedbed before 3-4 days before transplanting, and to transplant the cold tail to warm the day. The transplanting depth is suitable for the cotyledon flat soil, and the root water is lightly planted after planting. Cover the small arch film in time.
5, after planting the seedlings, use 10-15 kg of quick-acting nitrogen and potassium fertilizer per acre to drip with water, and add the fungicide or strong root agent at the same time.
