The summer solar term has passed, and these 5 points of agricultural management are indispensable to help you promote high yields.

The Great Heat is the 12th solar term in the 24 solar terms, and it is also the hottest period of the year. From the agricultural point of view, it is a period when many heat-loving crops grow relatively fast. However, in the process of crop growth, many agricultural management cannot be neglected.

1. Drought prevention

The summer heat has arrived, the temperature is very high, and the water in the field evaporates quickly. The growth of crops requires sufficient water. If there is drought in the field, it will affect the normal growth of the crops. Therefore, it is necessary to irrigate in time to replenish water.

2. Drainage

Recently, everyone can see through TV and the Internet that there are floods in many areas. From the perspective of agriculture, it has a great impact on the growth of crops. Therefore, we must do a good job in drainage work. In addition, after the floods, the damage of diseases and insect pests has increased, and at the same time. It is prone to hardening, so it is necessary to do a good job in field management. Secondly, for the land with severe flooding, it is necessary to change other crops in a timely manner to reduce losses.

3. Anti-high temperature

In the case of high temperature, although it is suitable for the growth of some crops, if the temperature is too high, it will bring adverse effects. It can be cooled by irrigation. On the other hand, some foliar fertilizers or growth regulators can be sprayed to improve the stress resistance of the crops themselves and reduce the harm of high temperature.

4. Prevention and control of pests and diseases

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 pollution-free, residue-free, 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.
