Fruit tree yellowing disease preventing and treating method and special comprehensive preparation

Abstract

The invention belongs to a fruit tree yellowing disease preventing and treating comprehensive preparation in fruit tree fertilizers. The preparation comprises (1) a foliage spray micro element fertilizer comprising the following components in percentage by weight: 18-22% of sequestration iron, 13-17% of magnesium, 13-17% of boron, 18-22% of zinc, 9-11% of silicon, 9-11% of selenium, 9-11% of kalium, 0.02% of endogenous hormone and 0.02% of gibberellin, total being 100%, and adding 500-700 times of water for foliage spray; (2) a root-irrigation conditioner comprising the following components in percentage by weight: 11-14% of sequestration iron, 45-55% of citric acid, 2-3% of soil conditioner, 30-40% of nitrogen, phosphorus and potash fertilizers which are same in amount, and trace of protease, total being 100%; and adding 40-60 times of water for the root-irrigation; and (3) a stem-coating nutritional agent comprising the following components in percentage by weight: 18-22% of sequestration iron, 0.1-0.3% of humic acid, 0.1-0.3% of fulvic acid, trace of aspartic acid and threonine and the balance of soft water penetrating agent, total being 100%; and adding 10-20 times of water for stem-coating. After kiwi fruit flowers, before a fruit expanding period (the first-ten and middle ten days of June), the foliage spray micro element fertilizer (the sequestration iron and multiple micro element nutrient solution) can be sprayed on leaves, meanwhile the conditioner (multiple nutrients and enzyme compounds and endogenous root-generating healing agents) is performed. A leaf fast green comprehensive preventing and treating preparation is coated on stems for the serious fruits. Triple effect is united as one, and the purpose of curing the yellowing disease is achieved.

Description

technical field [0001] The invention belongs to the technical field of pesticide manufacture, in particular to a preparation for preventing and treating fruit tree yellowing disease. Background technique [0002] my country's fruit area ranks first in the world. Among them, the emerging kiwifruit industry is 1.5 million mu, with an annual output of 1.1 million tons. Shaanxi Province's kiwifruit is 960,000 mu and 860,000 tons, ranking first in the world in both output and area. Due to yellowing, rotten roots are very common, accounting for about 20% of the cultivated area, about 300,000 mu or more. Including peaches, cherries, apricots, apples, citrus and other fruit trees, about 9 million acres of yellowing disease occurred, and the direct economic loss was 200 kilograms per mu, about 200 million kilograms. The annual loss due to yellowing disease was 400 million yuan. At present, various pesticides are not ideal for the prevention and treatment of fruit tree yellowing dise...
