Look at high-yield cultivation techniques for vegetable planting

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.

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, fertilizers should be used scientifically and reasonably, and proportioned and applied according to the growth of vegetables and the fertility level of soil.

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.

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 set up reasonable tillage, crop rotation and fertilization system in the process of green vegetable cultivation, and strengthen the management of vegetables.

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.
