Fruit tree leaf yellow and dry is a common plant disease, which will have a certain impact on the growth and development of fruit trees. In the cultivation of fruit trees, the yellow and dry leaves of fruit trees are one of the more common problems, so it is necessary to take timely measures to deal with them. This article will introduce in detail how to deal with the yellow and dry leaves of fruit trees to help fruit farmers solve this problem.
1. Cause analysis.
1.Nutrient insufficiency: A common cause of yellow and dry leaves in fruit trees is nutrient deficiencies. Fruit trees have a greater demand for nutrients such as nitrogen, phosphorus, and potassium, and if there is a lack of certain nutrients in the soil, it will cause the leaves to yellow and dry up.
2.Pest and disease infestation: The yellow and dry leaves of fruit trees may also be caused by pest and disease infestation. Pests and diseases such as locusts, aphids, anthracnose, etc., will cause damage to the leaves of fruit trees, yellowing and wilting.
3.Soil environmental problems: Soil environmental problems such as improper soil pH, poor drainage, and poor ventilation conditions can also lead to the yellow and dry leaves of fruit trees.
Second, the treatment method.
1.Supplemental nutrients: First of all, check the nutrient content of the soil, and supplement the insufficient nutrients according to the test results. Fertilization can be done with chemical fertilizers, and the appropriate ratio of fertilizer is selected according to the variety and growth stage of the fruit tree.
2.Pest control: When fruit trees are attacked by pests and diseases, control measures should be taken in time. Pesticides can be sprayed, and the dosage and frequency of use can be paid attention to to prevent harm to fruit trees. At the same time, the source of pests and diseases in the field should be cleaned up in time to reduce infection.
3.Improve the soil environment: For the situation that the soil pH is not suitable, the pH of the soil can be adjusted by applying lime, ammonium sulfate and other substances. For poorly drained soils, drainage improvements should be carried out to ensure smooth soil drainage. For places with poor ventilation conditions, branches can be pruned to increase ventilation air circulation.
4.Strengthen management: Strengthen the daily management of fruit trees, including timely pruning, weeding, and water retention, which will help fruit trees grow healthily and reduce the occurrence of leaf yellowing and drying.
3. Preventive measures.
1.Check the nutrient status of the soil and fruit trees, and apply fertilizer regularly to replace the missing nutrients.
2.Pay attention to pest control, regularly check the leaves of fruit trees for signs of pests and diseases, and take timely control measures.
3.Pay attention to the pH and drainage status of the soil, and make adjustments and improvements in time.
4.Select the right varieties of fruit trees according to local climatic conditions and soil characteristics to improve the resistance of fruit trees to diseases and pests.
Summary: For the treatment of the problem of yellow and dry leaves of fruit trees, we must first find out the cause of the problem, and then take targeted measures to deal with it. Strengthening the daily management of fruit trees, regularly checking the nutrient status of soil and fruit trees, and making corresponding adjustments will help prevent and solve the problem of yellow and dry leaves of fruit trees. At the same time, it is also one of the important measures to regularly clean up the sources of pests and diseases in the field and strengthen the control of pests and diseases. Through integrated management, the growth and development of fruit trees will be improved, as well as yield and quality will be improved.
