Problems solved by technology

There have been a lot of reports at home and abroad on the biological control of soil-borne pathogens using antagonistic bacteria. Many strains are not ideal in field production. One of the reasons is that the antagonistic microorganisms directly introduced into foreign soil cannot colonize well in the soil and become dominant. population

preparation example Construction

[0014] Preparation of fermented organic fertilizer: Collect various organic matter and crush them and then extract them. Take the extract and mix it with PDA medium to determine its antibacterial effect on several soil-borne pathogenic bacteria, and screen the organic matter first. The effect of organic matter on plant growth was determined in a pot experiment, and the organic matter was determined to be chicken manure, edible fungus waste, bean straw powder, cottonseed cake, bean cake and shell powder. The proportion of chicken manure, edible fungus waste, bean straw powder, cottonseed cake and bean cake is 20-30%, 40-50%, 5-10%, 2-5%, 2-5%, and the water content is about 60%. Mix and stack in the cement pool, carry out aerobic fermentation, turn over the pile every 3 to 5 days, finish the fermentation in 20 to 30 days, and air dry to become fermented organic fertilizer.

[0016] Example: Effect of Biological Soil Additives on Potted Cucumber Fusarium Wilt

[0017] Cucumbers are planted in nutrient pots, sown with diseased soil in multi-year continuous cropping sheds, and the addition amount of biological soil additives is 1% (W / W), 2%, 3%, and 5%, respectively, and mixed with diseased soil, so as not to add The diseased soil of the plant was used as the control, and 12 pots were treated for each treatment, and three repetitions were performed. Investigate cucumber emergence 10 days after sowing, investigate plant growth (plant height, underground fresh weight, and aboveground fresh weight) 30 days after sowing, investigate the incidence of cucumber Fusarium 30 days after inoculation, and investigate the effects of different treatments on the content of Fusarium wilt in the soil.

Abstract

The present invention belongs to the technical field of crop organic biological fertilizer, in order to solve the increasingly seriously continuous cropping obstacle of vegetable planting, lighten the occurrence of disease and improve the output and the quality of the vegetable, biological soil additive which can prevent the disease and as well as increase the production is confected, comprising two microorganisms, nonmetal mineral, fermented organic fertilizer, industrial waste residue and mineral microelement. The components comprise the weight proportion as follow: 10 percent of trichoderma functional microbial agent, 2 percent of VA arbuscular mycorrhizal fungi, 6 percent of inorganic nonmetal mineral zeolite, 69 percent of fermented organic fertilizer, 4 percent of shell powder, 7 percent of calcium superphosphate and 2 percent urea. The present invention is widely applied to the vegetable planting at the protected field with seriously continuous cropping and successive cropping and has the functions of improving the soil, promoting the crop nutrient absorption, increasing the output and preventing the disease.

Description

technical field [0001] The invention relates to a soil additive containing two kinds of microorganisms and an organic-inorganic mixture. The invention belongs to the technical field of crop organic biological fertilizer. Background technique [0002] The patent of the invention is a kind of biological soil additive that prevents diseases and increases production in order to solve the increasingly serious continuous cropping obstacles in protected vegetable cultivation, reduce the occurrence of diseases, and improve the yield and quality of vegetables. Slow down the occurrence of continuous cropping obstacles by improving soil nutrients to promote nutrient absorption, inhibiting soil-borne diseases, decomposing or transforming self-toxic substances, and inducing resistant substances. [0003] Due to the development of facility agriculture, the original farming system collapsed, and the specialization of vegetable production and planting habits led to the aggravation of obsta...
