In the daily management of pomegranate trees, fertilization and pruning should be the two aspects that can most affect the flowering and fruiting of pomegranate trees. Here I mainly talk about these two aspects.
Fertilization: firstly, fertilize in spring, and the dormancy period of pomegranate trees ends in spring. During this period, vegetative growth was dominant, and nitrogen fertilizer was dominant. Fruit farmers can choose urea or ammonium bicarbonate for fertilization. If urea fertilizer is used, it is about 25 kilograms per mu of orchard, and if ammonium bicarbonate is used, it is about 50 kilograms per mu of orchard. If it is a pomegranate tree planted at home, use some rotten cake fertilizer.
Fertilization in summer is the key period for the reproductive growth of pomegranate trees. At this time, attention should be paid to the coordinated use of nitrogen, phosphorus and potassium fertilizers. In autumn, pomegranate trees consume a lot of nutrients. At this time, the organic fertilizer can be topdressing with appropriate amount of urea. Potassium dihydrogen phosphate fertilizer can also be sprayed appropriately.
Shaping and pruning: open up the light source, cultivate strong tree potential and improve the dormancy quality of fruit trees in winter. Pomegranate should have sufficient light throughout its growing period. Prune and clean the garden in time after fruit picking (late autumn). After defoliation, prune and remove long branches, pests, overlapping branches, weak branches, inner branches and parallel branches, and spray the whole tree with "general tree protection"+stone sulfur mixture or magnesium arsenic. Prevent freezing injury, eliminate the source of overwintering diseases and pests, apply more nitrogen, phosphorus and potassium fertilizers, and pour frozen water to promote the rejuvenation of trees and recharge their batteries. For the larger wound (diameter 1 cm or more) caused by pruning, it should be immediately sealed with oily "healing antiseptic film" to make it heal quickly.
