The fruit trees have entered the fruit expansion period. What should I do if the weather is relatively dry?

High temperatures can easily cause atmospheric dryness, increase crop water evaporation, reduce soil moisture conditions, and cause drought. Drought can cause the stomata of fruit tree leaves to no longer be closed, aggravating water evaporation from branches and leaves, directly affecting the growth and development of oil fruits and leading to physiological fruit drop. High temperature and drought can also reduce the photosynthesis of fruit trees, increase the respiration intensity of fruit trees, reduce the synthesis and accumulation of organic nutrients, and affect oil and growth and eye differentiation. High temperature and drought weather, orchard growth or grass covering are very important response measures. 3354 Fruit tree roots are their brains and are very sensitive to external environmental conditions. The suitable temperature for the growth of most fruit tree roots is between 13 and 26 degrees Celsius, above 30 degrees Celsius or below. 0 will stop growing. After the fruit tree roots stop growing, the white capillary roots that actually absorb nutrients accelerate aging, which is very detrimental to the absorption and storage of nutrients. Orchards using orchard grass can reduce surface temperatures by 3-5% in summer, establish an ecological stable layer at the roots, prolong root growth time, and promote tree nutrient absorption and synthesis.

In response to hot and dry weather, necessary irrigation of fruit trees in a timely manner can not only improve soil moisture supply and orchard temperature and humidity conditions, but also meet the water demand for leaf evaporation and fruit expansion, and alleviate drought and high temperature heat loss. Harm to fruit trees. Especially in orchards with long drought periods, it is not possible to pour a lot of water suddenly and cause a lot of stagnant water. It is best to irrigate frequently with small amounts of water to avoid causing roots and cracks. In response to hot and dry weather, the role of watering trees is more obvious. 3354 with temperatures above 35. We can sprinkle water on the canopy at 5 p.m., when the sun is no longer exposed, to lower the temperature, increase humidity, improve the microclimate of the orchard, and alleviate the damage to trees and fruits caused by high temperature and direct sunlight.

In the process of fruit tree management, fruit trees enter the expansion period. High temperatures and droughts bring many difficulties to fruit tree growers. At this time, many people are at a loss. What management must be done? High temperature weather can easily cause atmospheric dryness, increase crop water evaporation, reduce soil moisture conditions, and induce drought. Drought causes the stomata of fruit tree leaves to remain open, and water evaporation from branches and leaves increases, which directly affects the growth and development of oil fruits and flower bud differentiation, leading to physiological fruit drop. Hot, dry weather tends to cause bars to dry out and fruit to burn. In particular, there are many weeds in orchards, which provide a place for various pests to eat, aggravating the damage caused by diseases and insect pests such as white powder, aphids, spider mites, and broad beans.

Adhere to the guiding ideology of focusing on prevention, comprehensive preventive treatment and the principles of early treatment, minor treatment and treatment. The pesticides should be fully sprayed once a month. It is found that there are no obvious diseases and insect pests in the fruit trees. Diseases and insect pests should be prevented in time, and highly toxic and strong irritating fragrances should not be used. In short, we should adopt a prudent scientific attitude, rationally use planting, chemical, physical and other methods and other effective ecological means according to local conditions, and do a good job in preventing and managing pests and diseases.
