I. Two main points of pollution-free production technology for melons and vegetables

1. Environmental conditions of origin

(1) The environmental conditions of the production area meet the requirements of NY 5010.

(2) Soil conditions: flat terrain, convenient drainage and irrigation, deep soil plows, suitable soil structure, and good physical and chemical properties. Silt loam, loam, and light clay are suitable, and soil fertility is high.

2. Cultivation measures

(1) Variety selection. Choose disease-resistant, high-quality and high-yield varieties, strong resistance to stress, wide adaptability, and good commerciality. Seed quality should comply with GB 16715.

(2) Land preparation. It adopts high tillage cultivation and mulching film to facilitate drainage and irrigation and reduce pests and diseases.

(3) Sowing. According to the meteorological conditions and variety characteristics, the appropriate sowing date is selected. Autumn cabbage is generally sown in late summer and early autumn. South China is generally sown in autumn and harvested at any time after the leaves are mature. Can be used for hole or drill sowing, cover the fine soil 0.5 ~ 1 cm after sowing, flatten and compact.

(4) Field management. After emergence and time, the seedlings will be fixed at 7 ~ 8 leaves. If there is a lack of seedlings, they should be replanted in time. Reasonable watering: timely watering after sowing to ensure that the seedlings are strong; till watering after seedling, planting or replanting to promote seedling return; watering at the initial stage of the rosette to promote hair growth; Combining fertilization and watering at the beginning and the middle of the heart, and proper water control in the later period promotes the filling.
