High-yield cultivation techniques for vegetable planting, so that the harvest of vegetables will be good

High-yielding Vegetable Cultivation Techniques

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

2. Choose high-quality vegetables

The high-yield cultivation of vegetables requires the selection of high-quality vegetable species. The selection of vegetable species must conform to the climate and soil of the cultivation area. The planting cycle of high-quality vegetable species is relatively short, the ability to resist natural disasters, diseases and insect pests is relatively strong, and the market is strong. demand and bring economic benefits.

3. Cultivate strong seedlings

Cultivating strong seedlings is conducive to the high-yield cultivation of vegetables. With the improvement of vegetable planting technology, seedling cultivation promotes the high-yield cultivation of vegetables. The process of raising seedlings is complicated, and not only requires high technical requirements, but also requires high technical content. Before cultivation, do a good job in the disposal of seeds, disinfect and fundamentally dispose of seeds by soaking seeds with trace elements, low temperature treatment, etc., and then stop the germination of seeds; dispose of bed soil, bed soil and nutrient cup soil. high.

4. Scientific application of fertilizers

In the process of vegetable growth, it is necessary to apply fertilizer scientifically. Scientific fertilizer dosage can promote the growth of vegetables, but if too much fertilizer is applied, it will affect the quality of vegetables. In high-yield cultivation, fertilizers should be used scientifically and rationally.

5. Plant adjustment

During the growth process of vegetables, plant adjustment should be carried out in time, and the growth status of vegetables should be improved by adjusting the time and space distribution of vegetable stems, leaves, fruits, and the structure of vegetables. The main contents of plant adjustment include: erecting, pruning, topping, thinning fruit, threshing leaves and pressing vines.Reasonable regulation of irrigation frequency and irrigation amount

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 the growth of vegetables, the number and frequency of irrigation must be separated from the characteristics of the climate. If the climate of the year is relatively dry, the number and frequency of irrigation can be increased, otherwise, 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. Therefore, during the growth of vegetables, the humidity and temperature of the vegetable environment should be well controlled. Vegetable farmers can place temperature and humidity monitoring points according to the size of the vegetable field, environment and other factors, and monitor the temperature and humidity of the vegetable field in real time. Reduce the temperature of the field, increase the humidity of the soil, and promote the growth of vegetables.

pest control

1. Agricultural control

High-quality and stress-resistant green vegetables should be selected, and pest-free and seed-free areas should be established in vegetable gardens to prevent the seeds of green vegetables from spreading diseases, pests and weed seeds. At the same time, growers should establish a rational system of farming, crop rotation and fertilization in the process of green vegetable cultivation, and strengthen the management of vegetable fields, and regularly liquidate their vegetable gardens.

2. Biological control

In the process of biological control, growers should first choose drugs that are non-polluting, non-residue, and will not cause harm to crops and human body, so that the drugs can timely and effectively deal with the diseases and insect pests present in vegetables, and play a good preventive role. Effectively ensure the safe consumption of green food.

3. Physical and mechanical control

In the process of physical and mechanical control, growers should scientifically control the selection of seeds, the selection and disposal of chemical agents, soil disposal methods, greenhouse cultivation and disposal methods, and pest and disease hunting and trapping methods.

4. Chemical control

The chemical control method has the advantages of wide application range, quick effect and remarkable control effect. During the implementation of the chemical control law, farmers should control the dosage of chemical pesticides, and after long-term, continuous, and large-scale use of pesticides, clean and sterilize the affected and polluted environmental areas to prevent the crops in the area from being harmed by pesticides .
