Microbiological enveloping compound fertilizer capable of improving nematode killing efficiency

Abstract

The invention provides a microbiological enveloping compound fertilizer capable of improving a nematode killing efficiency. The microbiological enveloping compound fertilizer consists of a three-layer structure, wherein the inner part of the three-layer structure is a compound fertilizer core layer, the middle of the three-layer structure is an oily enveloping substance, and the outer part of the three-layer structure is bacterium powder with an insect killing function, the weight ratio of the compound fertilizer core layer to the oily enveloping substances to the bacterium powder with the insect killing function is (300-600) to(1-5) to (1-10), the oily enveloping substances comprise liquid organic carbon of which the content of organic matters is more than 40%, and the number of effective viable bacteria of the bacterium powder with the insect killing function is larger than or equal to 5 hundred million/g. The microbiological enveloping compound fertilizer disclosed by the invention can realize the purpose of increasing the rate of crops for preventing and treating nematode.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, and relates to a microbial-coated compound fertilizer for improving nematode killing efficiency. Background technique [0002] Fertilizer is an accelerator to help plants grow, but the absorption rate of plants to fertilizer is limited, and its absorption and loss coexist. On the one hand, the lost fertilizer causes pollution of farmland, groundwater and waste of resources. On the other hand, crops die because they cannot absorb fertilizer efficiently. lead to a decline in yield and quality. Starting from the fertilizer itself, prolonging its own release rate so that plants can effectively absorb it to reduce pollution and promote growth is the goal that is constantly pursued in the field of fertilizer technology. [0003] At present, due to the extensive use of chemical fertilizers and pesticides, the unreasonable combination and application of organic fertilizers and biological fertiliz...

Problems solved by technology

This technical solution mixes organic matter with inorganic fertilizer, and its inorganic fertilizer can be nitrogen fertilizer, phosphorus fertilizer and potassium fertilizer, which makes organic matter possibly oxidized by substances in inorganic fertilizer (such as nitrate), resulting in poor fertilizer efficiency

[0005] CN105622240A discloses a water-retaining fertilizer for peanut planting, which is characterized in that the components of the raw materials are composed as follows in parts by weight: 8-10 parts of urea, 20-30 parts of tea leaves, 8-12 parts of iron slag, 3 parts of filler -5 parts, plant ash 5-7 parts, abamectin 0.6-0.8 parts, microbial agent 0.3-0.5 parts, potassium chloride 2-4 parts, magnesium sulfate 2-4 parts, zinc nitrate 3-5 parts, phosphoric acid 2-4 parts of manganese, 1-2 parts of ferrous sulfate, 0.8-1.2 parts of copper sulfate, 3-4 parts of boric acid, 2-3 parts of sodium tripolyphosphate, 1.2-1.4 parts of lysine, 3-5 parts of humic acid part, 3-5 parts of auxiliary agent, the microbial bacterial agent of this invention is the mixed bacterial agent of Bacillus thuringiensis, lactic acid bacteria and Trichoderma according to the composition of weight ratio 2:3:3, this invention is beneficial to improving soil structure and soil air permeability, improving Soil fertility and water retention capacity, the abamectin in the adhesive has remarkable insecticidal and insect-proof effects, and greatly reduces the harm of nematodes. The invention has a good short-term effect, but the slow-release effect is poor, and the technical solution uses Abamectin is a highly toxic insecticide, which is toxic to the human body
