Apply basic fertilizer Appropriate amount of organic fertilizer after fruit harvesting in autumn is conducive to the accumulation of nutrients in the tree. Fertilization method: dig a circular fertilization trench with a depth of 30-50 cm and a width of about 40 cm at the outer edge of the canopy, or dig a radial fertilization hole with a depth of 30 cm and a width of 20 cm at the outer edge of the fruit tree around the fruit tree with the main trunk of the fruit tree as the center. , Dig trenches on the same day, fertilize on the same day; the amount of fertilization depends on the tree vigor, tree age, soil fertility and output of the year, and the general fertilizer is catty. Plastic pruning Reasonable pruning can improve the light transmission conditions of the tree, increase the utilization of light energy, and achieve the effects of accelerating young tree growth, early fruiting, prolonging fruit period, reducing pests and diseases, improving fruit quality and extending tree life. The shape of the pomegranate tree is more random, generally equipped with 4 to 7 main branches evenly, 1 main branch with 2 to 3 side branches. Young trees that are growing vigorously should be lightly cut and long-released, focusing on cultivating the backbone branches to achieve the purpose of early formation and early fruiting; strong branching force in the full fruit stage, easy to canopy, strong trees should be more sparse and less cut, weak trees should be appropriately short Cut off the branches. Deeply clear the garden Most diseases and insect pests overwinter in the soil in the form of bacteria, oospores or larvae and pupae. Therefore, deep turning of the orchard in winter can smother or expose insects, pupae, and germs, allowing birds to peck or freeze to death. In order to eliminate the overwintering pests in the pomegranate orchard, regardless of the size of the pomegranate or the size of the pomegranate tree, a thorough deep pruning should be carried out before winter, and the litter, weeds and various pruned branches under the fruit tree should be carried out. Especially the diseased and pest branches, dry branches, dead buds and dead fruits, all of which are removed from the garden and burned together can reduce the incidence of diseases in the second year. After clearing the garden, turn over 20 cm deep to destroy the habitat of pests and the overwintering environment, and expose the overwintering bacteria and pests in the soil to freeze to death under low temperature. Pest control occurs At this time, the main control is pomegranate hemp and peach borer. The lesions that occur on the peel of pomegranate are collectively called "pepper disease", which is a comprehensive disease. The prevention and treatment of this disease is effective with 25% Segram EC. For the last generation of peach borer control method: use 25% chlorbenzuron No. 3 2000 times + 600 times agricultural resistance 120 + excellent fruit calcium 800 times + new high lipid film. While taking medicine, remember to remove pests and fruits. Disclaimer: Some articles on this website are transferred from the Internet.
