Four notes for safe fruit trees in summer

1. Shovel grass to loosen the soil. In the hot summer season, the soil management of the orchard should be strengthened, the orchard should be shoveled to loosen the soil, and weeds should be buried in the soil to avoid competition with fruit trees for water and nutrients.

2. Ditching and fertilization. Fruit trees need to consume a lot of nutrients to grow, develop, bloom and bear fruit. In the dry season, attention should be paid to strengthening fertilizer and water management to prevent falling leaves and fruit and promote fruit swelling. Fertilization should be based on organic fertilizers, combined with a small amount of nitrogen fertilizers and water. Generally, 50 kilograms of decomposed pig and cattle manure are buried for each plant of adult fruit trees, and at the same time, 15-25 kilograms of decomposed human feces or urine are applied, or 0.5-0.25 kilograms of urea and 15-25 kilograms of water are mixed and poured evenly. Fertilizing in the ditch. In orchards lacking phosphorus, potassium and trace elements, appropriate amounts of phosphorus and potassium fertilizers and trace elements should be applied to increase the drought resistance of fruit trees and increase fruit yield and fruit quality.

Third, the tree cover grass. According to many years of experiments, the tree cover with grass can prevent drought and reduce temperature in summer, and prevent freezing and heat preservation in winter. In high temperature and drought, cover grass can lower the ground temperature by more than 7 â„ƒ, reduce the temperature difference between the upper and lower layers of the soil, prevent the occurrence of sunburn and control the growth of weeds, and play a role in retaining water, fertilizer and improving drought prevention effects. Tree cover grass is usually cut into 10-15 cm long with straw, wheat stalk, dried weeds, silk grass, etc., with a cover thickness of 10-15 cm. Cover grass can be covered in the range of 1.5 to 2.5 meters of tree trays.

Fourth, pay attention to irrigation. Irrigation is one of the important measures to prevent high temperature and drought from harming fruit trees. During the summer drought, the amount of water evaporation is large, and there is no shortage of water. If the soil is too dry and the leaves appear curled and yellow, water should be timely irrigated, and sprinkler irrigation or micro-mist irrigation can be applied to orchards where conditions permit. Irrigation time should be from the evening to the morning until the irrigation is completed. In sunny days, irrigation is usually done every 7-10 days. Irrigation should be stopped in case of rain. After irrigation or watering measures, the body temperature of the fruit tree and the temperature of the soil can be adjusted, and the content of Vitamin C and sugar in the fruit can be increased.

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
