Kumquat, as a fruit tree loved by people, not only has delicious fruit flesh but also has high ornamental value. Recently, many kumquat growers have reported that the problem of kumquat dropping new leaves is becoming more and more serious, which has caused great difficulties for the growth of kumquat. This article will focus on this issue and provide a detailed introduction to the reasons and prevention methods for kumquat dropping new leaves.
Reasons for kumquat dropping new leaves1. Diseases and pests: The dropping of new kumquat leaves may be related to diseases and pests, such as spider mites, aphids, powdery mildew, etc. These diseases and pests will invade the leaves of kumquat, causing the leaves to turn yellow and fall off.
2. Improper water and fertilizer management: Water and fertilizer management is a key factor in the growth of kumquat. If the watering is excessive or insufficient, or the fertilization is improper, it may lead to kumquat dropping new leaves.
3. Environmental factors: Although kumquat has strong adaptability to the environment, attention should still be paid to environmental factors such as light, temperature, and humidity. Insufficient light, high or low temperature, and inappropriate humidity may cause kumquat to drop new leaves.
4. Excessive tree vigor: Kumquat with excessive tree vigor is prone to dropping new leaves, which may be due to uneven distribution of nutrients in the tree.
Prevention and control methods for kumquat dropping new leaves1. Disease and pest control: For diseases and pests, it is necessary to detect and take measures in a timely manner. Pesticides such as insecticides and fungicides can be used for prevention and control. It is important to strengthen the hygiene management of the kumquat garden, remove diseased leaves and branches, and reduce the spread of diseases and pests.
2. Water and fertilizer management: Water properly to keep the soil moist and avoid waterlogging. Fertilization should be based on the growth stage of kumquat and soil fertility, applying appropriate amounts of nitrogen, phosphorus, and potassium fertilizers. During the vigorous growth period, an appropriate increase in nitrogen fertilizer can promote leaf growth.
3. Improving the environment: Ensure that kumquat gets sufficient light, avoid direct sunlight, and water in time during high temperature and dry seasons to keep the soil moist. In winter, the temperature should be properly lowered to prevent kumquat from freezing.
4. Controlling tree vigor: For kumquat with excessive tree vigor, pruning and thinning can be used to adjust the tree structure and promote balanced distribution of nutrients.
Preventive measures for kumquat dropping new leaves1. Choose disease and pest-resistant varieties: When purchasing kumquat seedlings, choose disease and pest-resistant varieties to reduce the occurrence of diseases and pests.
2. Strengthen kumquat garden management: Regularly inspect the kumquat garden, detect and deal with diseases and pests in a timely manner, and maintain the hygiene of the kumquat garden by removing diseased leaves and branches.
3. Rational fertilization: Based on the growth stage of kumquat and soil fertility, fertilize rationally and avoid excessive fertilization.
4. Pay attention to environmental factors: Pay attention to the growth environment of kumquat and ensure that light, temperature, humidity, and other conditions are suitable.
Kumquat dropping new leaves is a common problem in the process of kumquat cultivation. Understanding the reasons and prevention methods is of great significance for ensuring the yield and quality of kumquat.
