Microbial fertilizer with continuous cropping resisting effect, preparation method and application thereof

Abstract

The invention discloses a microbial fertilizer with an anti-continuous cropping effect. The microbial fertilizer is prepared from the following components: 70-81% of an anti-continuous cropping compound bacteria solution, 4.5-8% of a chitosan hydrolysate, 4.5-6.5% of mineral source fulvic acid / mineral source potassium fulvate and 10-15.5% of wood vinegar, wherein the anti-continuous cropping compound bacteria solution is composed of a bacillus amyloliquefaciens bacteria liquid (1), a bacillus licheniformis bacteria liquid (2) and a brevibacillus laterosporus bacteria liquid (3), and the weight ratio of the bacillus amyloliquefaciens bacteria liquid (1) to the bacillus licheniformis bacteria liquid (2) to the brevibacillus laterosporus bacteria liquid (3) is (3-5):(1-2):(0.3-0.5). The preparation method comprises the step of mixing the components. According to the application of the microbial fertilizer to resistance of pepper and cucumber continuous cropping, when the microbial fertilizer is used for resistance of pepper continuous cropping, growth activity of root-knot nematode can be inhibited, new roots can be quickly promoted, absorption of roots to moisture and nutrients can be promoted, synthesis of chlorophyll can be promoted, and yellowing can be improved; and when the compound is used for resisting cucumber continuous cropping, the morbidity of cucumber fusarium wilt can be reduced, the cucumber yield is increased, the activities of soil sucrase, phosphatase, catalase and urease are improved, and the effect is remarkable.

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
