Bio-fertilizer for preventing and controlling root rot and preparation method thereof

Abstract

The invention belongs to the technical field of fertilizer production, and particularly relates to a bio-fertilizer for preventing and controlling root rot and a preparation method thereof. The bio-fertilizer for preventing and controlling root rot comprises the following raw materials: 150-240 parts of potassium humate, 50-150 parts of algae-derived kinetin, 30-70 parts of honeysuckle, 200-300 parts of ammonium polyphosphate, 5-20 parts of an earthworm powder, 10-25 parts of water-soluble bacillus subtilis, and 10-25 parts of bacillus licheniformis. The bio-fertilizer has the effects of rooting, strengthening seedlings and resisting root rot, stress and lodging.

Description

technical field [0001] The invention belongs to the technical field of fertilizer production, and in particular relates to a biological fertilizer for preventing and controlling root rot and a preparation method thereof. Background technique [0002] Root rot is a common disease in fruit tree production. The disease is caused by pests and pathogens. First, lesions appear from individual branch roots and fibrous roots, and gradually expand to the main root. As time goes by, the roots rot As the degree intensifies, the function of the roots to absorb water and nutrients gradually weakens, and the nutrients on the ground are insufficient. Once the fruit tree suffers from the disease, the side branches will die, the growth will be weak, and the whole plant will die in severe cases. Because root rot occurs in the lower part of the orchard, it is difficult to be found and diagnosed, which brings great difficulty to production and prevention. In addition, in recent years, some fru...

Problems solved by technology

Because root rot occurs in the lower part of the orchard, it is difficult to be found and diagnosed, which brings great difficulty to production control

In addition, in recent years, some fruit farmers have not fertilized scientifically and rationally enough, resulting in too much phosphorus in the soil being absorbed and utilized by fruit trees. It also has a certain antagonistic effect on nitrogen, which aggravates soil compaction and damages permeability, resulting in The disease resistance of fruit trees has been greatly reduced

In addition, some fruit farmers overuse ammonium bicarbonate, which can easily cause root burning, and unfermented and decomposed human and animal manure, straw, etc., which also aggravate the occurrence of root rot. This phenomenon has seriously affected the normal operation of the current fruit tree industry. develop

[0003] At present, agriculture mainly relies on irrigation and application of pesticides to diseased fruit trees to prevent and control root rot. The pesticides used generally include thiophanate-methyl, biclonal, dithyramine, copper sulfate, lime sulfur and "120 pesticides". etc., but in actual use, these pesticides either have a poor therapeutic effect (according to statistics, the therapeutic effect is less than 75%), or they recur severely in the later stage, and even cause serious phytotoxicity inadvertently (such as the application of copper sulfate, dithyramine, etc.) cause a large number of fruit trees to lose their leaves), destroy the soil structure and cause other diseases, etc.

In summary, the existing pesticide products can not effectively control the occurrence of fruit tree root rot
