Technical measures for promoting Flower and Fruit Protection of planting Shaddock

1. To promote flowering, in order to make fruit trees blossom early, one year before fruiting, the vegetative growth of the tree must be controlled, the growth center should be turned to reproductive growth, and flower bud differentiation must be promoted.

1. Control the vigorous growth of vertical roots, cultivate a large number of lateral and parallel roots, and promote flower bud differentiation.

2. Support, pull and drop the branches, increase the angle between branches and stems, weaken vegetative growth and promote flower bud differentiation.

3. Young trees with flourishing growth will cut the lateral branches in 1-2 circles from September to October.

4. In autumn, pay attention to drainage, water control, and cut off part of the root system, resulting in plant physiological drought, in order to promote flower bud differentiation.

Second, fruit protection

1. Increase tree nutrition, strengthen fertilizer and water management, retain leaves as much as possible, and prevent abnormal leaf fall.

2. Control the number of flowers and get rid of those malformed flowers and overdense flowers.

3. Regulate spring shoots and erase summer shoots. Too many spring shoots and excessive consumption of nutrients will aggravate fruit drop, and spring shoots should be regulated after budding. Mainly wipe off the strong spring shoots (vegetative branches) in the upper part of the crown, flower branches with more than 5 leaves, and late spring shoots; when the summer shoots sprout, wipe off the shoots many times until the fruit is set in mid-July.

4. Good prevention and control of diseases and insect pests: common diseases and insect pests include red and yellow spiders, leaf curl moths and resin diseases. 5. Spraying plant hormones, such as cytokinin, phytoxin, Jinyunda-120, etc.
