果树体养分的输送和运转是这样进行的:土壤中的矿物质营养(通过施肥等措施提供)和水分是通过根系吸收,由木质部输送到植株所需的各个部分;而叶片经过光合作用制造的光合产物有机营养,是通过韧皮部(树立)向下送往根系,供根系生长。环割、环扎就是通过闭口环割一圈树皮,切断了叶片光合作用制造的养
Fruit tree nutrients are transported and run as follows: Mineral nutrition in the soil (provided by fertilization, etc.) and moisture are absorbed through the roots and transported by the xylem to various parts of the plant; the leaves are made by photosynthesis Organic photosynthetic products nutrition, through the phloem (set) down to the root system for root growth. Ring cutting, cerclage ring is cut through the ring bark, cut off the photosynthesis leaves
