We usually need to go to the market to buy some melons and vegetables to cook, and we also hope to buy safe vegetables to cook, so there are many pollution-free melons and vegetables on the market now. The pollution-free production technology of melons and vegetables has been paid more and more attention by growers. Next, Bian Xiao will share two key points of pollution-free production of melons and vegetables.

First, two main points of pollution-free production technology of melons and vegetables

1, environmental conditions of producing area

(1) The environmental conditions of the producing area meet the requirements of NY 50 10.

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

2. Cultivation measures

(1) Variety selection. Select varieties with disease resistance, high quality and high yield, strong stress resistance, wide adaptability and good commodity. Seed quality should comply with GB 167 15.

(2) Soil preparation. Adopt high border cultivation and plastic film mulching to facilitate irrigation and drainage and reduce pests and diseases.

(3) sowing. Choose suitable sowing date according to meteorological conditions and variety characteristics. Autumn cabbage is usually sown in late summer and early autumn. South China usually sows in autumn, and the bulbs are harvested at any time after maturity. Hole sowing or strip sowing can be used, and fine soil can be covered after sowing. 5? 1 cm, flatten and compact.

(4) On-site management. Time interval after emergence, 7? Seedlings should be fixed when the leaves are 8, and replanting should be done in time if the seedlings are missing; Timely intertillage and weed control after seedling thinning, and intertillage for the last time before ridge sealing. Shallow before ploughing and deep after ploughing to avoid damaging roots; Reasonable watering: water in time after sowing to ensure that all seedlings are strong; Water after fixed planting, fixed planting or replanting to promote the seedlings to turn green; Watering in the early stage of rosette promotes the growth of trees; Combined with topdressing and watering in the middle and early stage, water control is appropriate in the later stage to promote coating.

Second, what are the melons and vegetables?

There are many kinds of melon vegetables, including cucumber, zucchini, pumpkin, zucchini, cucumber, towel gourd, Yunnan small melon, bitter gourd, white melon, eggplant melon, hairy melon, gourd, bergamot, snake melon and so on. Among them, cucumber is a popular vegetable for both fruits and vegetables, pumpkin and bitter gourd are health-care vegetables for both medicine and food, wax gourd is the main vegetable in autumn off-season, and other melons have different flavors and are all good meals. Cucumber vegetables have the following commonalities in cultivation:

1, pumpkin vegetables are thermophilic and heat-resistant crops, and they need sufficient light during their growth.

2. The root regeneration ability of melon vegetables is weak. In addition to direct seeding, seedlings should also be transplanted to protect the roots and cultivate strong seedlings.

3. Cucumber vegetables are vine crops, and the yield and quality of products can be improved by building scaffolding in production.

4. Most melons and vegetables should be harvested in time to prevent the product quality from declining after physiological maturity.

5. Cucumber vegetables are cross-pollinated by insects.
