An annual fertilization method for adult plum trees

Abstract

The invention discloses an annual fertilization method for adult plum trees, which comprises the following steps: (1) base fertilizer: base fertilizer is applied from the end of autumn to the beginning of winter after fruit picking, and the fertilization amount accounts for 60%-65% of the whole year; (2) flower-strengthening fertilizer : Before flowering, apply 17 kg of compound fertilizer and 17 kg of boron and zinc fertilizers per mu, accounting for 5%‑10% of the annual rate; (3) Stabilizing fruit fertilizer: apply 17 kg of water-soluble compound fertilizer per mu after the hard core stage of young fruit 34 kg and 17 kg of potash fertilizer, 0.5-1kg of water-soluble compound fertilizer and 0.5 kg of potash fertilizer are applied to each plant, and the amount of fertilization accounts for 15%-20% of the whole year; Potassium compound fertilizer 17-34 kg, 0.5-1kg high-potassium compound fertilizer per plant, the amount of fertilizer application accounts for 5%-10% of the year. The method of the invention makes the fertilization management of the adult plum tree more scientific, reasonable, economical and effective, achieves high quality, high yield and stable yield year after year, and greatly improves economic benefits.

Description

technical field [0001] The invention belongs to the technical field of fruit tree planting, and in particular relates to an annual fertilization method for adult plum trees. Background technique [0002] Fertilizer is the food of fruit trees and an important technical measure in the production and management of fruit trees. Whether the type, quantity and time of fertilization in orchards is reasonable or not directly affects the growth, yield, fruit quality and economic benefits of fruit trees. Different fruit trees have different characteristics of fertilizer requirements and different fertilization methods. How to scientifically fertilize according to the growth and development of fruit trees is the basis for improving the quality and efficiency of orchards. [0003] Prunus is a plant of the genus Prunus in the subfamily of Rosaceae, which is widely cultivated in the world, among which Chinese plum is the largest species in cultivated species. The plum is moderately sweet...

Problems solved by technology

However, at present, most of the plums in production are processed, and there are few varieties of fresh plums, and the cultivation and management of plum trees are extensive, especially the lack of fertilization technology. In production, there are low organic matter in the soil and excessive use of chemical fertilizers; improper combination of macronutrients and trace elements, Insufficient and excessive fertilization coexist, leading to soil nutrient imbalance, deficiency and excess coexist; improper fertilization time, resulting in fertilizer effect shifting or late defertilization; improper fertilization method, single fertilization method, inappropriate fertilization depth and other problems lead to low fertilizer utilization rate in orchards , the waste of fertilizer is astonishing, resulting in low yield and poor quality
