Embodiment 1

[0035] Stir fresh animal manure evenly as an organic fertilizer, and the water content of the organic fertilizer is controlled at 55%; mix the prepared organic fertilizer with organic bacteria and bran according to the mass ratio of 80:8:5 and stir evenly, and accumulate After 2 days of fermentation, the organic strains were multiplied to make strain fertilizer; then the strain fertilizer and organic fertilizer were mixed according to the mass ratio of 7:40 and stirred evenly. During this process, when the temperature rose to 50°C Finally, stir it once, pile up and ferment for 12 days to make organic bacterial fertilizer. In November of that year, 500kg / mu of organic fertilizer was spread on the orchard, and then shallowly plowed by 10cm to improve the microenvironment of the soil.

[0036] Ferrous sulfate, chelating agent and water are weighed according to the ratio of 4:1:160 according to the mass ratio, wherein the chelating agent is disodium edetate powder, first ferrous s...

Embodiment 2

[0038] Stir fresh animal manure evenly as organic fertilizer, and the water content of the organic fertilizer is controlled at 60%; mix the prepared organic fertilizer with organic bacteria and bran according to the mass ratio of 70:8:5 and stir evenly, pile up After 2 days of fermentation, the organic strains were multiplied to make the strain fertilizer; then the strain fertilizer and the organic fertilizer were mixed according to the mass ratio of 7:43 and stirred evenly. During this process, when the temperature rose to 60°C Finally, stir it once, pile up and ferment for 10 days to make organic bacterial fertilizer. In November of that year, 550kg / mu of organic fertilizer was spread on the orchard, and then shallowly plowed by 12.5cm to improve the microenvironment of the soil.

[0039] Ferrous sulfate, chelating agent and water are weighed according to the ratio of 4:1:170 according to the mass ratio, wherein the chelating agent is disodium edetate powder, first ferrous s...

Embodiment 3

[0041] Stir fresh animal manure evenly as organic fertilizer, and the water content of the organic fertilizer is controlled at 50%; mix the prepared organic fertilizer with organic bacteria and bran according to the mass ratio of 75:8:5 and stir evenly, stack After 2 days of fermentation, the organic strains were multiplied to make the strain fertilizer; then the strain fertilizer and the organic fertilizer were mixed according to the mass ratio of 7:45 and stirred evenly. During this process, when the temperature rose to 45°C Finally, stir it once, pile up and ferment for 11 days to make organic bacterial fertilizer. In November of that year, 600kg / mu of organic fertilizer was spread on the orchard, and then shallowly plowed by 15cm to improve the microenvironment of the soil.

[0042] Ferrous sulfate, chelating agent and water are weighed according to the ratio of 4:1:150 according to the mass ratio, wherein the chelating agent is disodium edetate powder, first ferrous sulfa...

Abstract

The invention discloses a method for preventing and controlling yellows of a kiwi fruit tree. By applying organic bacterial fertilizer and chelated ion fertilizer to the kiwi fruit tree, the content of organisms in soil is increased, the microbial population such as lactic acid bacteria and the like is expanded, and the iron supply condition of soil is improved so as to correct and cure the yellows of the kiwi fruit tree and produce high-quality kiwi fruits.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a method for preventing and treating kiwifruit tree yellowing disease. Background technique [0002] The yellowing of kiwifruit is mainly caused by iron deficiency or low content of available iron ions in the soil; insufficient application of organic fertilizers and iron fertilizers, and effective iron ions are fixed; partial application of nitrogen fertilizers, excessive use of ammonium bicarbonate in nitrogen fertilizers; improper fertilization types and fertilization methods and other reasons. Chlorosis can cause kiwifruit root rot, underdeveloped root system, and weakened absorption capacity. The existing method of preventing and treating yellowing disease is to adopt ferrous sulfate solution to spray the leaf surface, stem injection or root system immersion and other methods, and the effects are not ideal. Contents of the invention [0003] The object of ...
