Hawthorn must be managed carefully in autumn

Plastic surgery and trimming.

It is appropriate to adopt the natural evacuation hierarchical tree type, and the pruning principle is to attach equal importance to thinning, sparse branches, dense twigs, no overlap, crisscross and three-dimensional results. For overlapping, concurrent, crossover and competitive branches, select the poor ones, and cut off the disease and insect branches, dead branches and weak fruiting branches. The wound caused by pruning should timely use healing anti-decay film to protect wound healing tissue growth, prevent rot bacteria infection, prevent soil, Rain Water pollution, anti-freezing, prevent wound dry crack, in order to reduce nutrient consumption and improve flower quality and fruit setting rate.

Scientific management.

To prevent premature defoliation while doing a good job in the prevention and control of diseases and insect pests, drought should be properly irrigated and foliar sprayed with 600-fold liquid of new high-fat membrane, which can prevent leaf virus infection, prevent leaves from falling off prematurely, and affect the normal hanging of fruit and the improvement of quality next year.

Base fertilizer is applied in autumn.

After the soil is fully moist after rain, base fertilizer is applied, parallel ditches are opened at the dripping lines on both sides of the tree, organic fertilizer or bio-organic fertilizer is applied to 3 kg, and photosynthetic nutrient film fertilizer is sprayed on the foliage. It can help plants absorb a large amount of light fertilizer, light energy, light, compatible conventional fertilizers and nutrients to the limit of plant growth and development. One application is beneficial for the whole year.

Pest control.

Hawthorn fruit trees are vulnerable to powdery mildew, aphids, beetles and Lepidoptera larvae in autumn and early winter. To this end, spray a pest control agent in autumn, combined with foliar fertilizer, promoting flowers and so on. During the dormant period of fallen leaves, the whole garden was sprayed once to protect trees, thoroughly eliminating the source of overwintering diseases and insect pests. (Earth)
