Before germination to flowering: In order to prevent the deficiencies of zinc leaflets from the bud to the flowering and improve the stress resistance of the tree, spray 2000 ~ 3000 times of suspended zinc oxide solution; to prevent and treat the iron deficiency of peach leaves, spraying should be applied. EDDHA iron chelate 2000 to 3000 times solution.
Flowering period: In order to promote the flowering of peach trees and improve the fruit setting rate, the method of spraying sodium octaborate or potassium octaborate is preferred. The concentration is diluted to 800-1000 times solution, and the flowering period is sprayed 2 or 3 times.
Young fruit period: In order to reduce physiological fruit drop, prevent top rot, iron head, chapped fruit and other physiological diseases, increase fruit hardness, can be sprayed with sodium borates or potassium octaborates 1000 times solution, with sugar alcohol chelating calcium chelate Fertilizer 2000 times solution 2 or 3 times.
Fruit enlargement period and fruit coloring period: In order to promote the enlargement and coloring of peach fruit and improve the hardness and sweetness of the fruit, it is better to spray 1,000 times solution of calcium alcohol chelating sugar alcohol.
After Harvesting: Timely supplement of tree nutrients, delaying leaf senescence, enriching shoots and storage nutrients, guaranteeing germination and flower bud differentiation in the coming year; preventing lobular disease, improving resistance of trees, spraying 2000 to 3000 times of suspended zinc oxide Solution.
