Pomegranate Tree Autumn Management
First, re-application of autumn fertilizer, strong fruit tips
Before mid-September, it is necessary to revive a fruit-promoting fertilizer. Near the dripping line, dig 100-120 cm long, 30 cm deep and 30 cm wide fertilized fertilized fertilization. Each adult tree will be grown and 100 to 200 kg of superfluous manure or compost will be composted and superphosphate 1.5. - 2 kg, urea 1-1.2 kg. When the juvenile tree is reduced by half, the young tree is halved again.
Second, irrigation insulation, drought protection
In August-September, if a drought occurs in the orchard, it can be flooded and covered with weeds, wormwood, vines, etc. to preserve the drought and protect the fruit.
Third, sparse bud shoots, ring cut flowers
In late September, trees with less fruiting growth and less prosperous growth in the year were cut with a sharp budding knife and cut 1-3 full-circles on 2-3 branches to reach the xylem and promote flower bud differentiation. After circumcision, spray 0.2% potassium dihydrogen phosphate and 0.3% urea every 20 days, add 30-40ppm 2,4-D solution, spray 3-4 times continuously, and prevent defoliation in winter and spring. .
Four, long high contact, replace the good
At the beginning of September, the high-yielding trees that are under 20 years of age and that have grown normally are subject to high-yielding varieties. Using the method of "single (double) buds", the buds were evenly grafted on the erect and oblique branches with a diameter of about 2 cm in the middle and top of the canopy. After they survived, they piled down in April of the following year.
V. Forecasting and prevention of pests
From October to October, it focuses on the prevention and treatment of anthrax, rust mites, spider mites and arrowheads. In the autumn shoots, spray 800 times Daisen ammonium solution 1-2 times to control anthrax; to spider mites, observe the new shoots of the year, when there are about 5 heads, use 15% chlorbenzamide 3,000 times Liquid spray to kill 1 time; in mid-September for the sharp-early period, when the hatching rate of the young reaches 50%, spray 40% cullet EC 1200 times 1-2 times.
