Pomegranate Tree Autumn Management Technology

Re-apply autumn fat, strong fruit tips in mid-September, to re-apply a strong fruit to promote shoot fertilizer. In the vicinity of the drip line, excavate a circular fertilization ditch 1.0-1.2 meters long and 0.3 meters deep and wide. Fertilize every grown-up result tree, and apply 100-200 kg of super-composted manure or composted compost and calcium superphosphate. 1.5-2.0 kg, urea 1.0-1.2 kg. The juvenile tree is halved and the young tree is halved again.

Irrigation water insulation, drought and fruit protection in the August-September period of drought in the early or late irrigation of the orchard, the results of the tree each time not less than 100-150 kg. And use weeds, artemisia stalks, vines, etc. for ground cover, insulation and drought protection.

The buds are nourished and cultivated, and the flowers are cut and promoted in late September. For trees with less fruit and less prosperous growth this year, the 2-3 branches will be cut with a sharp budding knife to cut the entire ring 1-3 times, deep to the xylem. Promote flower bud differentiation. After circumcision, spray 0.2% potassium dihydrogen phosphate and 0.3% urea every 20 days, add 30-40 mg/kg of 2,4-D solution, spray 3-4 times continuously, and prevent defoliation in winter and spring. .

The bulls were high, and the good varieties were changed. In early September, bulls were planted with high yields for trees under 20 years of age and normal growth. 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.

Forecasts and prevention of pests August-October, focusing on the prevention and control of anthrax, rust mites, spider mites and arrowheads. In the autumn shoots, spray 800 times Daisen ammonium solution 1-2 times to control anthrax; for spider mites, observe the new shoots of the year, when there are about 5 per piece, use 15% Xenox net emulsion 3000 times solution Spray 1 time; in mid-September, the peak tip of the arrowhead was used. When the hatching rate of the pups reached 50%, 40% of the emulsion was sprayed with 1200 times of the emulsion 1-2 times.
