A kind of microbial fertilizer with anti-heavy cropping effect and its preparation method and application

Abstract

The invention discloses a microbial fertilizer with anti-stubble stubble effect, which is composed of the following components: 70%-81% of an anti-stubble-stubble compound bacterial solution, 4.5%-8% of chitosan hydrolyzed liquid, mineral source fulvic acid / mineral source fulvic acid Potassium acid 4.5%~6.5%, wood vinegar liquid 10%~15.5%; the anti-stubble compound bacteria liquid is composed of ① Bacillus amyloliquefaciens bacteria liquid, ② Bacillus licheniformis bacteria liquid and ③ Brevibacillus lateralis bacteria liquid The weight ratio of ①, ② and ③ is (3~5):(1~2):(0.3~0.5). The preparation method is as follows: mixing the components. The application of the microbial fertilizer of the present invention in resisting the continuous cropping of peppers and cucumbers can inhibit the growth of root-knot nematodes, rapidly promote new roots, promote the absorption of water and nutrients by the roots, and promote the synthesis of chlorophyll when used for the resistance to repeated cropping of peppers. Improve yellowing; when used for resistance to continuous cucumber cropping, it can reduce the incidence of cucumber fusarium wilt, increase cucumber yield, and improve soil invertase, phosphatase, catalase, and urease activities, with significant effects.

Description

technical field [0001] The invention relates to a microbial fertilizer with the effect of resisting heavy cropping, a preparation method and application thereof, and belongs to the technical field of microbial fertilizers. Background technique [0002] Continuous cropping, also known as continuous cropping, refers to growing the same crop on the same land for many years. At present, melons, fruits and vegetables with high economic value and some Chinese herbal medicines all have the phenomenon of repeated cropping. Repeated cropping can easily lead to obstacles to repeated cropping, aggravation of crop diseases and insect pests, and serious reduction in yield and quality. The obstacle of repeated cropping is a soil-borne disease, mainly due to the imbalance of rhizosphere soil nutrition caused by years of heavy cropping, the lack of some nutrients, the change of soil physical and chemical properties, the decrease of soil enzyme activity, the imbalance of crop rhizosphere mi...

AI Technical Summary

Problems solved by technology

Heavy cropping obstacles mainly harm the roots of crops, causing the roots to be hindered from obtaining the nutrients needed for growth, affecting crop growth, resulting in reduced crop yield and quality

[0003] There is currently no good control measure for heavy cropping obstacles. Chemical control is the fastest control method, but long-term use of chemical pesticides in large quantities will lead to environmental pollution, and it is easy to produce pesticide resistance, reducing the control effect

In addition, some existing anti-cropping products mainly supplement chemical elements, especially medium and trace elements, or apply bio-organic fertilizers, anti-cropping bacteria agents, etc., which have a single function, slow effect, short control time, and poor control effect. Mainly based on basal application, it is inconvenient to apply during the growth period of crops, and the addition of chemical elements can easily cause environmental and soil problems, which may aggravate the occurrence of diseases
