What is the impact of the recent heavy rainfall on young Shatangju? This seems to be based on the farm soil and management of the fruit farmers. The requirements for soil moisture content of sand orange in general are: sand soil moisture content is greater than 40%, loam soil water content is greater than 42%, clay soil moisture content heavy rain 45% need to drain. That is, if the soil moisture content of the above-mentioned nature exceeds a certain proportion, the earthworm damage will increase as the soil moisture content increases and time passes.
Because: When there is too much water in the soil, the pores in the soil are lack of oxygen due to the full of water, making the root system difficult to breathe and affecting the absorption of water and nutrients. In addition, due to the lack of oxygen in the soil, the anaerobic bacteria are active, resulting in some toxic reducing substances, causing the accumulation of harmful substances, which directly produces toxic effects on the root system. In severe cases, the plant death occurs; in addition, the plant damage also affects the photosynthesis of the plants. The energy consumption of the plant is greater than the synthesis of energy and affects plant growth. The empirical method for discriminating soil moisture, such as: Take soil below 10 cm, and crush by hand to form a mass is not easy to crack, indicating that the soil moisture has exceeded 45%.
At this point, we must take appropriate measures to reduce the soil moisture content. For example: timely drainage, shallow loose soil, so that the air can enter the pores of the soil in time; open the roots of the tree tops to allow water to evaporate as soon as possible, but also allow some of the root system to contact the air, depending on the weather conditions, 1 to 3 days and then re Cover soil; apply extra-root fertilizer. Because of the damage to the root system of the plant, the ability to absorb nutrients is greatly reduced, and the leaf surface can be sprayed with Amino Acid foliar fertilizer. For example, gold green fertilizer is added 500 times and 0.04 ppm of brassinolide is added to supplement plant nutrients in a timely manner to enhance root vigor and enhance the plant's resistance to stress and restore the tree vigor; timely pruning will cause serious damage and yellowing Leaves defoliate severe weak branches cut off to send new shoots.
Please refer to the above measures and refer to the application in conjunction with the actual situation of your fruit farm. In addition, there are many diseases that cause citrus damage, such as viral diseases, bacterial diseases, and fungal diseases, and there are also certain differences in the sources of various diseases. Management measures and preventive drugs are also different. Some diseases can be prevented or treated with the same drug, and some diseases should take targeted measures and drugs. What's more, for certain viral or bacterial diseases, there are still no effective drugs for treatment. They can only be prevented or removed from the orchard and burned.
