The recent high temperature continues, and the orchard management is facing a severe test. Understand the impact of high temperature on fruit trees, and adjust orchard management measures appropriately to prevent and control symptoms early. The soil in the orchard is too dry, the transpiration of the leaf and fruit surface is large, and the root system is not available for water, and sunburn will occur; the amount of water is too large, the soil is short of water, the root system cannot breathe, the water absorption capacity is deteriorated, and the water supply is less than The amount of transpiration of leaves and fruits can also cause sunburn. Reasonable watering to maintain the proper moisture content of the soil is the main means to prevent sunburn. Therefore, the soil should not be too dry or too wet. If you can lightly or alternately water the orchard before the high temperature comes, it can effectively reduce the occurrence of sunburn. In addition, when watering, it is necessary to avoid the noon high temperature period, choose the best watering in the morning and evening. Reasonable irrigation to prevent high temperature damage on the ground, suitable water spraying can reduce the damage of high temperature to the tree; during the expansion period, if the soil water content is less than 65% of the field water capacity, timely irrigation; the ground exposed nursery can be every 7 ～Irrigation once every 10 days; Orchards with orchards covered with grass can be irrigated every 15-20 days; At the same time, it is strictly forbidden to irrigate during high temperature periods (11:00～16:00), after the sun sets or at night Irrigation is best. For the orchard, we can choose ryegrass gentleman, tall fescue dynasty and sage. In the hot season, after the grass species grow to 30 cm in height, they will be cut and covered. Through the orchard grass growing and covering repeatedly, the ground can be covered with green plants in the high-temperature period of the orchard in the summer and protect the root system from damage. The covering material of the tree disc is suitable for local conditions, such as straw, weed, peanut shell, sawdust, etc. Before covering the grass, set up the tree tray, pour water or let it cover after raining. For grasses that have not been initially rotted, an appropriate amount of quick-acting nitrogen fertilizer should be applied in an appropriate amount, or the manure and urine of the rotted manure should be applied after the grass is mulched to prevent yellowing of the soil's short-term denitrification leaves caused by fresh grass rot. The thickness of the grass cover is preferably 15-20 cm. When the clay soil is covered with grass, it should be combined with ridge drainage to avoid water accumulation in the orchard soil, causing vigorous growth or rotten roots. At the same time, it should not be covered with grass about 20 cm around the trunk to prevent the stagnant water from affecting the root ventilation.
