New technology of vegetable planting

Vegetables are what we often eat. Vegetables are rich in nutrients needed by the human body. The prospect of growing vegetables is good, so, with the progress of science and technology, what is the new technology of growing vegetables?

I. selection of species

Good varieties of vegetables with high quality, high yield, early maturity and resistance to diseases and insect pests should be selected.

Second, prepare before sowing

1. Before sowing or planting, we should destroy stubble and plough as soon as possible, expose the soil, remove the residual stubble, branches and leaves, and eliminate the residual sources of bacteria and insects in the soil.

2. Do a good job of seed treatment: soak the seeds in warm water, that is, soak in 55 degrees warm water for 40 minutes for 15 minutes, which can kill the germs attached to the seed surface.

3. Adopt new technologies and achievements at home and abroad as far as possible. Such as nutrition bowl seedling, factory seedling, tissue culture, grafting, drip irrigation, plastic film mulching and so on. Start with the cultivation of strong seedlings to increase the disturbance to diseases and insect pests.

III. Field management

According to the different requirements of light, moisture and fertilizer of different vegetable varieties, high and short three-dimensional planting can be adopted to do a good job of intercropping and interplanting reasonably. Three-dimensional planting of different kinds of vegetables, three-dimensional cultivation of vegetables and edible fungi.

Strengthen management, and time seedling setting, pruning and forking, ploughing and weeding, removing diseased plants, and controlling the spread of diseases and pests.

IV. Fertilization

The main results are as follows: 1. The base fertilizer should be mainly organic fertilizer and should be fully mature to reduce the introduction of pathogenic bacteria and eggs.

2. Topdressing should be based on rotten manure and urine, supplemented by multi-component compound fertilizer, so as to prevent excessive topdressing of nitrogen fertilizer.

3, rational use of hormones and trace elements, strictly in accordance with the label description of the concentration and dose, to prevent excessive drug damage.

Prevention and control of diseases and insect pests

Prevention and control is based on physical and ecological methods, biological pesticides take the lead, home-made pesticides play a supporting role, high-efficiency and low-toxic residual chemical pesticides help, and highly toxic pesticides do not go into the field. "

The main results are as follows: 1. Adopt ecological method to prevent disease. Apply ecological management techniques such as temperature control, temperature regulation, high temperature bacteriostasis and so on.

2. Using physical method to kill Cordyceps sinensis. Use black light or a small amount of sugar, vinegar and wine to trap and kill pests; cover the insect control net and keep the pests out of the net, which can greatly reduce the dependence on chemical pesticides. Covered with silver-gray sunshade net to avoid winged aphids, blue film can better control grass damage.

3. Vigorously promote bio-pesticides and plant pesticides. Control of cabbage, diamondback moth and melon leaf borer with BT emulsion penicillium, cucumber anthracnose and Fusarium wilt with agricultural streptomycin, bacterial angular spot, Chinese cabbage soft rot and black rot with agricultural streptomycin, cucumber and eggplant virus diseases with attenuated vaccine, root rot and root rot with Jingfengmycin, aphid control with ET-107 and red spider with liuyangmycin Using EM as base fertilizer can improve the physical and chemical properties of soil and effectively avoid some destructive diseases. Soaking seeds with EM can obviously promote seed germination. If EM fertilizer spraying is used to control the diseases caused by Botrytis cinerea, it can have a better control effect. There is also a new vegetable pesticide nuclear polyhedrosis disinfectant, which also opens up a broad prospect for pollution-free vegetable production.

4. Use chemical pesticides scientifically. We must conscientiously implement the regulations on the Administration of pesticides and the regulations on the interval between Pesticide Safety, and strictly prohibit the use of highly toxic and highly residual pesticides such as DDT, methamidophos, and methyl isosinophos.

The use of advanced new technology to grow vegetables can reduce the production of diseases and insect pests, improve the quality of vegetables, and obtain high yield.
