Biological organic fertilizer with disease preventing function and preparation method thereof

Abstract

The invention discloses a biological organic fertilizer with disease preventing function and a preparation method thereof. The biological organic fertilizer with the disease preventing function contains thermophilic bacterium, actinomyces, streptomyces, adsorption carrier and fermentation carrier, wherein the weight ratio of the bacteria is 0.8-1.2:0.8-1.2:0.8-1.2, and the adsorption weight ratio of the mixed bacteria solution of the bacteria to the adsorption carrier is 1:1.25-1.75. The preparation method comprises the following steps of: performing seed culture and fermentation tank culture on the thermophilic bacterium, the actinomyces and the streptomyces respectively, mixing the bacteria according to a proportion, performing carrier adsorption to obtain a composite bactericide, and drying the composite bactericide at a low temperature till the water content is below 30 percent; and inoculating the obtained composite bactericide to the fermentation carrier to perform mixed fermentation, wherein the weight ratio of the composite bactericide to the fermentation carrier is 1: 3,000-1: 5,000. The biological organic fertilizer provided by the invention has the characteristics of broad pesticidal spectrum, short breeding cycle and disease preventing function.

Description

technical field [0001] The invention discloses a biological organic fertilizer with disease prevention function and a preparation method thereof, belonging to the field of microbial fermentation. Background technique [0002] Long-term application of chemical fertilizers will seriously damage the soil. If you want to restore the soil to its original physical and chemical properties and increase the beneficial bacteria and organic matter in the soil, you need a fertilizer with good fertilizer efficiency and spectrum anti-pest effects. Bio-organic fertilizer is a fertilizer prepared by microbial fermentation. It has less pollution and can increase the yield of crops. It is an indispensable fertilizer for the production of green food. [0003] The applicant is Ma Yuxin, the patent number is 200710059835, and the name is the preparation method and application of bio-organic fertilizer for preventing and controlling nematode damage. The disclosed method needs to carry out high-te...

Problems solved by technology

[0003] The applicant is Ma Yuxin, the patent number is 200710059835, and the name is the preparation method and application of bio-organic fertilizer for preventing and controlling nematode damage. The disclosed method needs to carry out high-temperature fermentation of bio-organic materials, and then carry out secondary fermentation. The cycle is long and the fermentation temperature is 30-35 ℃, easy to be contaminated by bacteria

Moreover, the prevention of pests and diseases is relatively simple, and it is only used to prevent and control the harm of nematodes, and the insecticidal spectrum is narrow.

[0004] The applicant is Zuo Shuzhen, the application number is 200510012308, the name is a kind of bio-organic fertilizer and its preparation method. A kind of bio-organic fertilizer is disclosed. Human and livestock feces, urine, Chinese herbal medicine residue, waste fungus culture medium, etc. are used as side materials. The preparation process requires anaerobic fermentation for 3-6 months (inoculated with thermophilic fungal microorganisms), and then aerobic fermentation for 5-14 days. , the fermentation temperature should be controlled below 55°C, this method also requires secondary fermentation, and the cycle is long: this will inevitably lead to incomplete harmlessness, not only can not have the effect of preventing diseases and insect pests, but also prone to miscellaneous bacteria pollution and harm crops.
