Microorganism compound fungicide, soil repairing agent and preparing method and application of fungicide

Abstract

The invention provides a microorganism compound fungicide, a soil repairing agent and a preparing method and application of the fungicide. The microorganism compound fungicide comprises bacillus licheniformis, bacillus mucilaginosus, yeast, nitrogen-fixing bacteria and microorganism growth aids. After the compound fungicide is reasonably combined with organic matter, a porous carrier and surfactin, the soil repairing agent for preventing and treating soil continuous cropping diseases is formed; the lost nutrients of a continuous cropping land can be compensated for, bacteria restraining and resisting substances can be generated through the metabolism effect of the microorganisms, and the soil physiochemical performance and soil structure of the continuous cropping land are comprehensivelyimproved from different aspects. The soil repairing is conducted on the soil continuous cropping land through various approaches, and the repairing effect is improved.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a microbial composite bacterial agent, a soil remediation agent, a preparation method and an application. Background technique [0002] The crops of the same species or the same family are planted in the same field for three or more consecutive seasons, which is called double cropping. Heavy cropping (continuous cropping) land is actually a land with severe toxins, viruses and viral diseases. Many crops, such as legumes, melons, vegetables, strawberries and some Chinese herbal medicines, etc., are caused by plant root pathogens due to heavy cropping, resulting in plant wilt, leaf blight, viral diseases and other hazards, seriously affecting crop growth. [0003] The causes of heavy cropping include the following: [0004] 1. Nutritional imbalance. Each crop has its favorite fixed nutrients. If it is continuously cropped for a long time, these nutrients it likes must b...

AI Technical Summary

Problems solved by technology

Each crop has a favorite fixed nutrient, and if it is continuously cropped for a long time, the nutrient it likes must be insufficient, resulting in growth disorders

[0005] 2. Self-poisoning and deterioration of the microenvironment

Crops have absorption and excretion. Harmful substances excreted by crop roots, such as organic acids (or residual roots that have not been removed), cause self-poisoning, and the soil itself cannot be decomposed, and will accumulate in the soil due to continuous cropping, resulting in poor crop growth.

[0006] 3. The flora is out of balance, and the pathogenic bacteria increase. The pathogenic bacteria and pests (especially nematodes) that are easy to infect the crops remain in the soil and accumulate due to continuous cropping, resulting in aggravated diseases

When the seedlings are cultivated under heavy cropping, due to the weak resistance of the seedlings, these pathogenic bacteria can easily invade the plants, resulting in the continuous occurrence of various diseases and endangering the health of the plants.

[0010] 2. Undernutrition

The nutritional requirements of the same plant are fixed, continuous planting will make the nutrient elements in the soil deficient, the crop nutrition will be unbalanced, and it will be difficult to grow normally

Careful growers may have discovered that the amount of fertilizer input into heavy cropping fields will increase year by year, and the simple fertilizer cost has already increased the economic burden of farmers!

[0011] 3. Seriously poisoned

[0012] 4. Soil problems

[0017] However, the above-mentioned measures all have the defect of single effect, and the effect of soil restoration is not good.
