How to manage the planting of yellow bark? Please introduce in detail that the cultivation of wampee can be managed with reference to the following methods: fertilization and soil management for young wampee trees planted for 1-3 years, the main purpose of fertilization is to promote growth and make them produce many new shoots in a year, so as to rapidly expand the crown and increase the leaf area. lay a good foundation for early fruiting and high yield. The principle of applying fertilizer frequently and thinly should be grasped, and fertilization can be applied once a year in February, May and August according to the situation of its hair shoot. In addition, orchard intercropping, ground mulching, irrigation and drainage, weeding and loosening soil and deep ploughing must be carried out in time to create good soil conditions for the growth of young yellow trees. The purpose of shaping and pruning young trees is to cultivate backbone branches, balance tree potential, regulate branch growth, make them form a certain number of main branches and side branches, form a strong crown skeleton, and lay a good foundation for early fruiting and high yield. The yellow bark crown should be cultivated into a round head shape, cut off at the height of 70cm to 80cm of the trunk, and then cultivate and distribute 3 main branches evenly, on which the lateral main branches and branches should be drawn to form a natural round head crown year by year. The pruning of young trees is mainly light short pruning, combined with proper branch thinning. During the period of vigorous growth of branches, coring can be appropriately removed to weaken the growth potential, stimulate the germination of 2-3 lateral buds under the cut, promote branching and increase growth. Every winter, cut off the withered branches, shade branches, over-dense branches, overgrown branches and disease and insect branches inside the crown to improve the ventilation and light transmission conditions inside the crown and prevent the occurrence of diseases and insect pests. The main diseases of wampee are anthracnose and soot. Anthracnose can be sprayed with 800-1000 times of chlorothalonil or 800 times of carbendazim, and soot should mainly control aphids and shell insects. To control shell insects, 1:20 turpentine mixture or 40% dimethoate 800 times solution plus 90% trichlorfon 800 times liquid can be used to control aphids, 50% trichlorfon 500 times liquid or 40% dimethoate 800 times liquid can be used to control aphids. 80% dichlorvos emulsion 1000 times or 50% omethoate 1000 times can be used to control leaf moths.
