Fertilizing method for peach trees

Abstract

The invention discloses a fertilizing method for peach trees. The fertilizing method comprises the following steps: base fertilizer is applied 15-30 days before leaves of the peach trees fall, and the base fertilizer comprises decomposed livestock manure, microbial fertilizer, medium-nitrogen, high-phosphorus and low-potassium water-soluble fertilizer and a microbial agent A; 7-15 days before flowering of the peach trees, 0.3-0.5 kg of urea is applied to each plant, high-concentration humic acid liquid fertilizer is applied, and 20-50 kg of the high-concentration humic acid liquid fertilizer is applied per mu; in the fruit setting period of the peach trees, medium-nitrogen calcium magnesium fertilizer, a microbial agent B and liquid level calcium fertilizer are applied; in the fruit expanding period, leaf fertilizer is sprayed to the peach trees twice, and water-soluble fertilizer is applied to the roots while the leaf fertilizer is sprayed; and the fertilizer is supplemented after fruit picking, and 0.3-0.5 kg of compound fertilizer and 0.2-0.3 kg of urea are applied to each plant. By the adoption of the method, soil in an orchard is effectively improved, biological control over diseases is achieved through the microbial agents, the number of times of pesticide application in the whole year can be reduced by 1-2 times, environmental pollution is reduced, the yield and the high-quality fruit rate are remarkably increased, the comprehensive quality is improved, the application amount of the chemical fertilizer is reduced by 40%, and the operation benefits of the orchard are improved.

Description

technical field [0001] The invention relates to the technical field of peach tree planting, in particular to a method for fertilizing peach trees. Background technique [0002] Peach (scientific name: Amygdalus persica L.): Rosaceae, peach. Deciduous small tree; leaves are narrowly elliptic to lanceolate, 15 cm long, 4 cm wide, apex grows and slenderly pointed, margin has fine teeth, dark green shiny, leaf base has nectaries; bark dark gray, Cracks appear with age; flowers are solitary, from light to deep pink or red, sometimes white, with short stalks, 4 cm in diameter, blooming in early spring; subspherical drupes, with hairy surfaces, edible flesh, orange-yellow pan Red, 7.5 cm in diameter, with deeply pitted and grooved core containing white seeds. [0003] Peach is originally produced in my country and is distributed all over the country. The main economic cultivation areas are in North China and East China provinces. The more concentrated areas are Beijing Haidian Di...

Problems solved by technology

[0005] However, the existing fertilization methods generally have the problems of heavy application of chemical fertilizers and light application of organic fertilizers, and the imbalance of phosphorus, potassium and medium and trace elements caused by partial application of nitrogen fertilizers is also very serious.

Improper management of nutrients has also caused many ecological problems related to peach production. For example, after excessive fertilization, soil nutrients are lost with runoff or infiltrated with water, polluting groundwater sources, and long-term partial application of fertilizers causes imbalance of mineral elements in peach trees. And antagonistic disease, affecting the normal growth and fruit quality of peach trees, etc.
