Preparation method of liquid fertilizer for preventing and treating banana wilt

Abstract

The invention discloses a preparation method of a liquid fertilizer for preventing and treating banana wilt.The preparation method comprises the following steps that 1, lactic acid bacteria accounting for 0.1%-0.5% of the weight of molasses-alcohol concentrated waste liquid and saccharomycetes accounting for 0.01%-0.05% of the weight of the molasses-alcohol concentrated waste liquid are added into the molasses-alcohol concentrated waste liquid, the materials are mixed to be uniform, and after natural fermentation is performed for 3 months, molasses-alcohol fermentation liquid is obtained; 2, 5-30 parts by weight of cassava extracting liquid, 2-20 parts by weight of nitrogen-phosphorus-potassium fertilizer, 0.1-5 parts by weight of medium trace elements and 5-40 parts by weight of the molasses-alcohol fermentation liquid prepared in the step 1 are put into a reactor, water is added to supplement the total parts by weight to 100, then beneficial bacteria are added, the materials are stirred to be uniform to enable the density of the beneficial bacteria to be 0.5-2 hundred million per milliliter, and the liquid fertilizer is obtained.The liquid fertilizer prepared through the method contains allelopathy inhibiting substances of fusarium oxysporum and has the positive effect on prevention and treatment of the banana wilt.

Description

technical field [0001] The invention relates to a method for making fertilizer. More particularly, the present invention relates to a kind of preparation method of the liquid fertilizer that is used for controlling banana wilt. Background technique [0002] Banana is an important economic crop in the tropical and subtropical regions of southern my country, but the occurrence of banana wilt has seriously affected the healthy development of the industry. Banana Fusarium wilt is a devastating disease and is an international phytosanitary target, caused by the infection of Fusarium oxysporum Cuban-specialized. Pathogenic bacteria survive in the soil for several years, generally reducing yield by more than 20%, and severe fields may even fail to harvest. Banana Fusarium wilt is a soil-borne vascular disease, and diseased banana seedlings and diseased soil are the primary source of infection. Factors such as high temperature and rainy, acidic soil, sandy loam, low fertility, he...

AI Technical Summary

Problems solved by technology

The above methods have a certain effect on the prevention and treatment of Fusarium wilt of banana, but they also have great limitations.

The use of chemical pesticides will make the soil micro-ecological balance more unbalanced, and the types and quantities of soil flora will decrease, resulting in insufficient microbial activity in the soil, resulting in soil compaction and lower nutrient absorption and utilization; at the same time, chemical pesticides are also easy to pollute the soil, which is harmful to food. Safety is also a hidden danger

Microbial control has always been the focus of industry research, and now the main problem is that beneficial bacteria colonize and play a role in the soil after use has not been resolved

After the use of beneficial bacteria, most of them are inhibited by indigenous bacteria and cannot colonize. In addition, the organic matter content in the soil is too low, and it is even more difficult for foreign bacteria to survive
