1、 Improper moisture
Reason: in the process of planting apricot trees, long-term lack of water will make it difficult to absorb water in the soil, and the leaves will naturally close the pores, resulting in curling and folding. On the contrary, if the garden is low-lying and has serious ponding for a long time, it will also make the soil lack of oxygen, inhibit respiration, hinder the transportation function, and also lead to leaf curling p>
Solution: water according to the needs of growth at ordinary times. When there is a lack of water, water can be supplied slowly and gradually to make the water penetrate into the root. After the rain, drainage should be promoted to avoid ponding p>
2、 Improper fertilization
Reason: for apricot trees, the root needs fertilizer to promote growth. Applying non rotten fertilizer or high concentration of chemical fertilizer will not cause root damage and leaf curling p>
Solution: fertilize according to the growth trend. Do not fertilize too much, but also pay attention to the concentration. Apply thin fertilizer as many times as possible. When fertilizing too much, it is necessary to water and dilute to promote discharge p>
3、 Infectious diseases and insect pests
Reason: if apricot trees are infected with root rot, ground tigers and other diseases and pests, the roots will also be damaged, the absorption capacity will be problematic, and the leaves will curl p>
Solution: Fungicides such as chlorothalonil can be used to treat root rot, and corresponding agents can be used for treated pests p>
