Problems solved by technology

Spraying foliar fertilizer is an effective way to grow strong trees, resist diseases and increase yields. The method is simple and easy to use. The fertilizer is economical and the effect is obvious. However, due to the low level of farmers’ awareness, it is not possible to use zinc nutrients according to the different growth stages of fruit trees. The application of different concentrations of foliar fertilizers will cause the fertilizers to fail to fully exert their effects. Generally, when spraying low-concentration foliar fertilizers, the absorption of leaves is limited, and good results cannot be achieved.
[0005] The existing method for preventing and treating small leaf disease of fruit trees has the following defects: (1) the incidence rate of small leaf disease is high; (2) the efficiency is low and the effect is slow; (3) the leaf area of ​​fruit trees is small, the yield is low, and the commercial fruit rate is low; ( 4) Blind use of fertilizer, and fertilizer damage has occurred; (5) The method is complicated and the cost is high

Embodiment 1

[0040] Example 1 A method for supplementing fruit tree zinc fertilizer and preventing and controlling leaflet disease

[0041] In 2008, in the test base of Binhai Development Zone, Weifang City, 50 6-year-old red Fuji apples were selected for testing according to this implementation method, and two treatments were set up:

[0042] 1. Using the method of the present invention to prevent and treat lobular disease:

[0043] (1) Spraying high-concentration foliar fertilizer in late spring dormancy

[0044] Before the apple tree's spring dormancy ends, before the tree germinates, spray the foliage containing 1% urea, 2% zinc edetate, 0.5% iron edetate, and 0.01% sodium dodecyl benzene sulfonate For the fertilizer mixture, adjust the pH to 5 with citric acid and spray it twice in a row with an interval of 8 days.

[0045] (2) Spraying high-concentration foliar fertilizer for the first time during leaf maturity

[0057] Example 2 A method for supplementing fruit tree zinc fertilizer and preventing and controlling leaflet disease

[0058] In 2008, 60 five-year-old'Xiadan' peach trees were selected and bred in the experimental base of Binhai Development Zone, Weifang City, and tested according to the present invention. Two treatments were set up:

[0059] 1. Using the method of the present invention to prevent and treat lobular disease:

[0060] (1) Spraying high-concentration foliar fertilizer in late spring dormancy

[0061] Before the peach tree's spring dormancy ends and the tree germinates, spray a foliar fertilizer mixture containing 1% urea, 1.8% amino acid chelated zinc, 0.6% amino acid chelated iron, and 0.01% sodium dodecylbenzene sulfonate. Adjust the pH to 4.6 with citric acid, spray twice in a row with an interval of 7 days.

Abstract

The invention provides a method for supplementing zinc fertilizer to fruit trees and controlling the little leaf disease. The method comprises the following steps: high-concentration foliar fertilizer is sprayed in late spring dormancy, sprayed in a leaf mature period for the first time and sprayed in the leaf mature period for the second time. The high-concentration foliar fertilizer with different formulae is sprayed in fruit tree leaf slow growth or dormancy stages such as the late spring dormancy, the leaf mature period and senescence period and the like of the fruit trees, and the little leaf disease of the fruit trees is controlled. With adoption of the method, the little leaf disease control effect is obvious, the little leaf disease incidence rate after spraying in an orchard is smaller than 1%, and the method has especially obvious effect on control of the little leaf disease of the fruit trees in saline-alkali soil.

Description

Technical field [0001] The invention relates to a method for supplementing zinc fertilizer for fruit trees and preventing and controlling lobular disease, and belongs to the technical field of agriculture. Background technique [0002] Fruit tree leaflet disease is a physiological disease caused by the lack of zinc. It mainly damages the new shoots and leaves. In the early stage of the disease, the internodes of the new shoots are short, and the top leaflets are clustered or bald, easy to fall early, difficult to flower and hard to set, and low yield Or not. The organic matter formed by time synthesization in fruit trees cannot function normally due to zinc deficiency, which leads to chlorosis of leaves, hindered growth, and affects yield and fruit quality. Zinc deficiency is common in sandy land, alkaline soil, barren land and mountain orchard, especially in saline-alkali land. At this stage, the main methods of preventing and controlling lobular disease are as follows: [0003...
