(I) Late growth management. The first is to strengthen fertilizer and water management. Summer temperatures are higher, plant growth is strong, and there is a large demand for nutrients. It is necessary to add water and fertilizer in a timely manner. Topdressing can be combined with watering, mainly with compound fertilizer or phosphorus and potassium fertilizers. The second is temperature regulation. In summer, the temperature is high, and it is necessary to focus on the ventilation and cooling of vegetable greenhouses. Before and after noon on sunny days, large ventilation is needed in the greenhouses, which will be slightly smaller in the morning and evening. After mid-June, shade cultivation will be carried out. Third, the leaves are defragmented, and the deformed fruit is removed. The yellow leaves and diseased leaves in the middle and lower parts of the plant are timely removed to reduce the nutrient consumption, improve the ventilation and light transmission, reduce the occurrence of diseases, and improve the commercial quality of the fruit.

(b) greenhouse soil treatment. After more than half a year of vegetable cultivation, the number of pathogens and pests in the greenhouse soil increased significantly, directly affecting the growth of sorghum vegetables. Therefore, after the vegetables are pulled, serious soil disinfection and killing of harmful organisms in the soil are effective measures to control pests and diseases in greenhouses. Specific methods: After the harvest of vegetables, clean the field, add fertilizer, and then turn the ground leveling. In July-August, when the temperature reaches 35°C or higher, the temperature will rise to 50-60 when covered with plastic film and cover. °C, after 15-20 days, most of the bacteria and pests in the soil can be killed. If you use lime nitrogen solar disinfection, the effect is better. Specific methods: 80 tons of lime nitrogen per acre, wheat straw and other unripe organic materials 1-2 tons, plowing, hoeing, watering, filming about 15 days, can kill most of the pests in the soil. If the use of liquid lime nitrogen disinfection, the use of more convenient and better.

Amino Acid

Another important function of amino acids is to provide energy to the human body. Normally, a healthy body on a general diet will use carbohydrates as its main fuel, but when the main source is depleted due to strenuous exercise, protein and amino acids can be used as a last resort. Amino acids also play an important role in food taste. Protein doesn't have much taste, but each amino acid has its own taste, and combining them is one of the important factors that define the taste of food
