Vegetable planting high-yield cultivation technology, so that the vegetable harvest will be good

Technical requirements for high yield vegetable cultivation

1, the choice of soil

The quality of soil directly affects the growth of vegetables, so it is necessary to select suitable soil for efficient cultivation of vegetables. The selection of soil should separate the growth characteristics of vegetables and integrate the needs of sunlight, wind, water and other elements of vegetable growth. It is necessary to improve the fertility level of the soil and ensure the efficient consumption of vegetables.

2, choose high-quality vegetable types

The high-yield cultivation of vegetables should choose high-quality vegetable types, the selection of vegetable types should conform to the climate and soil of the cultivation region, the planting cycle of high-quality vegetable types is relatively short, the resistance to natural disasters, diseases and pests is relatively strong, and the strong market demand and bring economic benefits.

3. Cultivate strong seedlings

With the improvement of vegetable planting technology, seedling cultivation promoted the high-yield cultivation of vegetables. The seedling process is complex, not only the technical requirements are high, but also the technical content requirements are high. The technical points of seedling cultivation are mainly five parts: before cultivation, we should do a good job of seed disposal, stop the disinfection and fundamental disposal of seeds by means of trace element immersion and low temperature treatment, and then stop the germination of seeds; Dispose of the bed soil, the nutrition of the bed soil and nutrient cup soil should be high, and the soil contains a lot of decomposed organic matter, in addition, the field soil, livestock feces, soil ash and sand should be reasonable proportion; Enhance humidity and temperature management in the greenhouse to ensure that the seedbed soil is suitable for seed development; Nitrogen fertilizer, phosphate fertilizer and potassium fertilizer should be used during seedling cultivation, and potassium dihydrogen phosphate and boric acid and zinc sulfate mixture should be sprayed 2-3 times during seedling cultivation. Start seedling cultivation 7~10d before planting.

4. Apply fertilizer scientifically

In the process of vegetable growth, fertilizer should be applied scientifically. Scientific fertilizer dosage can promote the growth of vegetables, but if too much fertilizer will affect the quality of vegetables. In high-yield cultivation, fertilizer should be used scientifically and reasonably, and scientific fertilizer ratio and application should be stopped according to factors such as vegetable growth and soil fertility level.

5. Plant adjustment

In the process of vegetable growth, it is necessary to stop plant adjustment in time, and to improve the growth of vegetables by stopping the adjustment of the time and space distribution of vegetable stems and leaves, fruits and the structure of vegetables. The main contents of plant adjustment include: erection, pruning, core picking, fruit thinning, leaf breaking and vine pressing.

Reasonable control of irrigation frequency and irrigation quantity

Scientific irrigation contributes to the rapid growth of vegetables, especially in modern agricultural consumption, people pay more and more attention to the importance of irrigation. In vegetable growth, it is necessary to separate the characteristics of the climate and determine the number and frequency of irrigation. If the climate of the year is relatively boring, the number and frequency of irrigation can be increased, and conversely, the number and frequency of irrigation can be reduced to avoid the death of vegetable seedlings.

The regulation of temperature and humidity for the growth of high-quality vegetables

The efficient growth of high-quality vegetables is inseparable from scientific temperature and humidity, so in the process of vegetable growth, it is necessary to control the humidity and temperature of the vegetable environment. Vegetable farmers can place temperature and humidity monitoring points according to the size of the vegetable field, environment and other factors, and stop real-time monitoring of the temperature and humidity of the vegetable field. When the temperature is too high or the humidity is too low, the atomization water can be stopped to reduce the field temperature, improve the soil humidity, and promote the growth of vegetables.

Control of pests and diseases

1. Agricultural prevention and control

High-quality green vegetables with strong stress resistance should be selected, and disease-free planting fields and seed retention areas should be established in vegetable parks to avoid spreading diseases, pests and weed seeds on green vegetable seedlings. At the same time, farmers should establish a rational cultivation, crop rotation and fertilization system in the process of green vegetable cultivation, and strengthen the management of vegetables, regularly stop the liquidation of the garden, and try to choose eggplant, melon, cucumber, watermelon and other grafting techniques to effectively control the harm of infectious diseases.

2. Biological control

In the process of biological control, farmers should first choose drugs that are pollution-free, no residue, and will not cause harm to crops and human bodies, so that drugs can promptly and effectively dispose of diseases and pests present in vegetables, and play a good preventive role, effectively ensuring the safe consumption of green food. Biological control work is mainly aimed at pests and pathogenic bacteria, so in the theoretical link, more and more targeted drugs should be selected to stop preventive management.

3, physical and mechanical prevention

In the process of physical and mechanical control, farmers should scientifically control seed selection, chemical selection and disposal, soil disposal methods, greenhouse cultivation and disposal methods, disease and insect hunting and trapping methods. In the process of killing pests, the use of high-pressure pump lights, or the use of sweet and sour trapping, yellow board trapping and poison bait trapping, to ensure that green vegetables will not be disturbed by pests and diseases.

4, chemical control

The chemical control method has the advantages of wide application range, quick effect and remarkable control effect. In the implementation of the chemical Control Law, farmers should control the dosage of chemical pesticides, and stop cleaning and disinfecting the affected and polluted environmental areas after long-term, continuous and large-scale use of pesticides, so as to prevent crops within the site from being harmed by pesticides
