A kind of application method of fruit tree foliar fertilizer

Abstract

The invention provides a method for effectively applying fruit trees foliar fertilizers, which comprises steps: high concentration foliar fertilizers are sprayed in dormant periods of fruit trees, are sprayed for the first time after blades mature, are sprayed for the second time after the blades mature, and are sprayed in old periods of the blades. The method for effectively applying the fruit trees foliar fertilizers spray different formulas of high concentration foliar fertilizers according to growth characteristics and nutritional requirements of the blades in fruit tree growth and development stages from the dormant periods of the fruit trees, after the blades mature to the old periods which are in mature periods of the blades of the fruit trees without blades. The method for effectively applying the fruit trees foliar fertilizers improves disease resistance, is extremely light in fruit tree physiology disease and rapid in fertilization effect, and has effects after being sprayed for 3-7 days.

Description

technical field [0001] The invention relates to a method for applying fruit tree foliage fertilizer, which belongs to the technical field of agriculture. Background technique [0002] my country is a big fruit producing country in the world. At the end of 2011, my country's fruit cultivation area was about 11 million hectares, accounting for 1 / 5 of the world's total fruit cultivation area; the national annual fruit production was about 94 million tons, accounting for about 15% of the world's total fruit production. The fruit industry has become one of the pillar industries of my country's rural economy, playing an important role in the adjustment of agricultural industries and increasing farmers' income. [0003] In order to promote the growth of fruit trees and increase the yield of fruit trees, it is necessary to manage the fertilization of fruit trees in different periods of fruit tree growth. At present, the fertilization methods of fruit trees are mainly ground fertili...

AI Technical Summary

Problems solved by technology

Ground fertilization mainly uses nitrogen, phosphorus and potassium fertilizers, but lacks the application of trace element (calcium, iron, zinc, boron, etc.) fertilizers, resulting in various physiological diseases of fruit trees such as small leaf disease, yellow leaf disease, and bitter pox due to the lack of trace elements. etc., seriously affected the growth and yield of fruit trees; spraying foliar fertilizers can supplement trace elements, but because the farmers' awareness level is not high, they cannot apply different formulations of foliar fertilizers according to the nutritional needs of fruit trees at different growth stages, resulting in trace elements. Elements cannot fully play their role and have the desired effect

[0004] The patent document whose patent number is 201310084480.X discloses a method of annual application of red Fuji apple foliar fertilizer, which is based on the red Fuji apple before germination, after germination, flowering period, new shoot flourishing period, fruit expansion period, fruit development period and The growth characteristics and nutrient demand characteristics of the seven red Fuji apples in the key stages of growth and development before the leaves fall. Spraying suitable foliar fertilizers can effectively improve the apple fruit setting rate, improve fruit quality, and increase fruit yield. However, the number of sprays is too high. It consumes a lot of manpower and material resources; the spraying process is complicated and difficult to master; and the method of the invention is mainly to apply foliar fertilizer in the young leaf period of the leaves. The absorption is limited and the effect is poor

[0005] The prior art has the following defects: (1) poor disease resistance of fruit trees and serious physiological diseases; (2) low fertilization efficiency and slow effect; (3) low yield of fruit trees and low rate of high-quality fruit; (4) foliar fertilizer Low absorption rate, prone to fertilizer damage
