Medical fertilizer and application thereof

Abstract

The invention relates to medical fertilizer. The medical fertilizer is prepared from the following components in parts by weight: 10 to 78 parts of rice vinegar, 0 to 6 parts of calcium superphosphate, 0 to 9 parts of monobasic potassium phosphate, 0 to 8 parts of ferric sulfate, 0 to 39 parts of rice wine and 20 to 77 parts of compound bacteria, wherein the compound bacteria are prepared from the following components: 8 percent to 12 percent of bacillus subtilis, 10 percent to 20 percent of pediococcus pentosaceus, 8 percent to 12 percent of aspergillus niger, 3 percent to 8 percent of bacillus mucilaginosus, 3 percent to 8 percent of rhizopus oryzae, 1 percent to 5 percent of pichia farinose, 1 percent to 5 percent of sphingobacterium multivorum and 40 percent to 60 percent of ferment bacterium expanded liquid. According to the medical fertilizer, a living space of pathogenic bacteria is inhibited through utilizing microbial bacteria and various substances capable of inhibiting the pathogenic bacteria are secreted, and the effect of preventing and controlling diseases is realized; the compound bacteria have very good compatibility with the rice vinegar and other components, so that the disease prevention and control effects of the medical fertilizer can be improved. The medical fertilizer provided by the invention has better effects on prevention and control of the diseases including grey mold, white blight, soft rot, powdery mildew, bacterial spot, canker, venturia inaequalis, brown rot, scab and the like of crops.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a medicinal fertilizer and its application. Background technique [0002] Our country is a large agricultural country, which requires a large amount of chemical pesticides to prevent and control crop diseases and insect pests every year. Although chemical pesticides play a great role in increasing crop yield and quality, many problems have appeared in long-term use, such as pesticide residues, resistance of pathogenic bacteria or pests, etc., resulting in The control effect is poor and the control difficulty is increased. [0003] At present, most of the medicinal fertilizers at home and abroad are chemical pesticides added to the fertilizer. Although it has the effect of preventing diseases and insect pests, it has certain toxicity and is not friendly to the environment. In addition, some biopesticides have also been developed.

[0002] Our country is a large agricultural country, which requires a large amount of chemical pesticides to prevent and control crop diseases and insect pests every year. Although chemical pesticides play a great role in increasing crop yield and quality, many problems have appeared in long-term use, such as pesticide residues, resistance of pathogenic bacteria or pests, etc., resulting in The control effect is poor and the control difficulty is increased

[0003] At present, most of the medicinal fertilizers at home and abroad are chemical pesticides added to the fertilizer. Although it has the effect of preventing diseases and insect pests, it has certain toxicity and is not friendly to the environment.

In addition, some biopesticides have also been developed. Biopesticides refer to preparations that use living organisms or their metabolites to kill or inhibit agricultural pests. Judging from the current use effects, these biopesticides have low residues. The effects of resisting crop diseases and insect pests and regulating crop growth are not satisfactory
