Key points of cultivation techniques of super-early red peach
1. Tree shape and density: open field cultivation can adopt three main branches happy shape or free spindle shape, suitable density 3 m × 4 m or 2 m × 4 m, greenhouse cultivation tree shape can adopt trunk free shape or inverted "human" shape, suitable density 2 m × 1 m.
2. Control the amount of fruit retained: the fruit setting rate of this variety is high, and fruit thinning must be carried out. Fruit thinning begins 10-15 days after flowering, leaving 3-4 fruits on long fruit branches and 1 fruit on short fruit branches, which is generally controlled at 12000-15000 per 667m2.
3. Fertilization by stages: 2-3 cubic meters of organic fertilizer per 667 square meters before sprouting, 30 kg of diammonium phosphate during fruit expansion, 40 kg of three-element compound fertilizer after fruit picking, and 2-3 cubic meters of organic fertilizer after defoliation. Foliar fertilization is sprayed once a week from fruit expansion to maturity.
4. Summer pruning: cut off fruitless branches, erect strong branches, leafless fruit branches and weak branches in time after fruit setting; remove strong and long branches outside the crown during the young fruit growing period; remove dense branches and old and weak branches in time in order to improve the light conditions of the tree after fruit picking.
5. control of diseases and insect pests: focus on the control of peach aphids and bacterial perforation. Peach trees were sprayed with 3-5 Baumedo stone sulfur mixture before sprouting to control overwintering diseases and pests, 1500-fold solution of 10% aphids were sprayed before anthesis and once after Xiehua to control aphids, and bacterial perforation could be sprayed with 80-1000 times of methyl topiramate at the initial stage of the disease.
