Problems solved by technology

[0002] At this stage, root-knot nematode disease is spreading rapidly due to soil compaction and acidification, and the disease is getting worse year by year. In some vegetable planting areas, the incidence rate reaches 100%, the yield loss is 30-50%, and the serious loss reaches 80%.

Embodiment 1

[0026] This implementation is used for the water-soluble fertilizer of nematode prevention and control, and content is all by weight, is made up of following raw material: Paecilomyces lilacinus fermented liquid 45%, γ-PGA fermented liquid 26%, alanine 10%, chitosan 1.5% , potassium alginate 7%, chelated element calcium magnesium 3%, thickener sodium carboxymethyl cellulose 0.5%, desalinated water 7%.

[0027] Wherein the gamma-PGA fermented liquid contains gamma-PGA with a mass fraction of 2.5%. The strain used in the present invention is Bacillus subtilis.

[0028] Wherein the effective conidia content in Paecilomyces lilacinus fermented liquid is 3 billion / gram. The strain used in the present invention is Paecilomyces lilacinus, which was isolated from tomato nematode-infected plants by the research and development team of Hubei Phosphate Group.

[0029] The above-mentioned method for preparing water-soluble fertilizer for preventing and controlling nematodes comprises th...

Embodiment 2

[0033] The steps are the same as in Example 1, only the mass fraction of potassium alginate is 8%.

Embodiment 3

[0035] The steps are the same as in Example 1, only the mass fraction of potassium alginate is 9%.

Abstract

The invention discloses an amino acid water-soluble fertilizer. The water-soluble fertilizer is prepared from paecilomyces lilacinus fermentation liquor, polyglutamic acid fermentation liquor, micromolecular amino acid, chitosan oligosaccharide, potassium alginate, chelated medium elements and a thickening agent. The product has the advantages that the fermentation liquor is directly used, so thatthe centrifuging or filtering process is avoided, and the cost is reduced; paecilomyces lilacinus is relatively good in nematode control effect, safe and free of pollution. The potash fertilizer increases the toughness of crop roots and can effectively prevent nematode infection; the micromolecular amino acid can be directly absorbed and utilized by the root system to promote rapid growth of thecrop root system or rapid recovery of the damaged root system; chitosan oligosaccharide is matched with organic matters, so that the influence of root-knot nematodes on crops can be reduced, and combined infection of bacteria or fungi on plant root systems is reduced. The microbial agent and the water-soluble fertilizer raw material can be mutually dissolved after being mixed, the solution is in astable colloid state, and conidia of the microbial agent can stably survive and keep biological activity for a long time.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to an amino acid water-soluble fertilizer for protecting roots and preventing nematodes and a preparation method thereof. Background technique [0002] At this stage, root-knot nematode disease is spreading rapidly due to soil compaction and acidification, and the disease is getting worse year by year. In some vegetable planting areas, the incidence rate reaches 100%, and the output loss is 30-50%, and the serious loss reaches 80%. The annual loss of vegetables alone in my country is as high as 20 billion yuan, which causes great losses to the country. The control of nematode disease has always been dominated by chemical pesticides, which are now banned by the state due to their high toxicity and high residues. Biological control methods have become the only way to prevent and control nematode diseases. [0003] Paecilomyces.lilacinus is an endoparasitic fungus and ...
