Description

The preparation method of strawberry specific complex successive planting resistant agent
Technical field
The invention belongs to the preparation of mikrobe compound preparation, be meant a kind of preparation method of strawberry specific complex successive planting resistant agent especially.
Background technology
The strawberry berry is scarlet gorgeous, fragrant succulence, and sweet acid is good to eat, and is nutritious, is regarded as treasure in the fruit.The existing planting strawberry area in the whole nation is nearly 40,000 hectares at present, more than 20 ten thousand tons of output.Strawberry continuous cropping disease is the major issue that strawberry produces; Domestic and international research shows; The major cause that causes continuous cropping is due to the shortage and soil-borne disease of soil nutrient elements, and strawberry is 2 years general underproduction 10-15% of continuous cropping on the piece of same field, 3 years underproduction 20%-25% of continuous cropping; Continuous cropping underproduction more than 40% more than 4 years, severe patient even total crop failure.
In the strawberry cultivating process, particularly the continuous cropping plantation very easily causes the nutrient deficiency of soil, and replenishing coherent element rationally and effectively is important measures in the modern agriculture plantation.The strawberry disease is that main, common anthrax, gray mold, Powdery Mildew and root rot etc. are all propagated by bacterium and mould with soil-borne disease; Virus disease mainly contains various plants viruses such as strawberry mottle virus, strawberry light yellow edge virus, strawberry veinbanding virus, mainly by aphis propagation; The insect pest of strawberry is main has strawberry bud nematode, strawberry pratylenchus, red spider and aphid.
The method that present strawberry wants continuous cropping generally to adopt is exactly the chemical fumigation method.More than 15,000 yuan, only good for the year of issue only, stifling simultaneously is violent in toxicity with chemical substance to this method use cost mostly, and atmosphere and soil are all had serious destruction up to per hectare.Under the continuous condition of enlarged in strawberry industrialization market, the green non-pollution product demand is also enlarged day by day.The biological control that the strawberry continuous cropping is sick to the requirement of environmental protection and green food, all has very important significance to improving the strawberry competitiveness in the international market.
Along with the development of green food, green agriculture, bio-feritlizer begins to be used on a large scale on the modernized agricultural planting, and in bio-feritlizer, microbial fertilizer is few with its consumption, cost is low, action effect significantly forms and is first-selection.The potassium phosphorus composite fertilizer that colloid bacillus cereus with potassium decomposing effect and the bacillus megaterium with phosphate solubilization are processed is widely used a kind of microorganism live bacteria preparation in bio-feritlizer market in recent years.Microbial fertilizer is at culture fertility, and the raising chemical fertilizer utilization ratio purifies and rehabilitating soil, and reduce corps diseases and take place, the protection environment, and aspects such as raising crop products quality and food safety have all shown irreplaceable effect.
Streptomyces microflavus ( Streptomyces micrcflav) to be a strain have the antibiosis actinomycetes of antagonistic action to multiple pathogenic bacteria, the antibiotic fertilizer with this bacterial strain is produced not only can suppress the growth of multiple pathogenic bacteria, also has effects such as the crop of stimulation germinates, takes root.Actinomycetes fertilizer has been obtained good disease-resistant, effect of increasing production in use for many years.Producing antibiotic fertilizer with streptomyces microflavus at present has solid and two kinds of methods of liquid fermenting, and the solid fermentation production cycle is longer, unstable product quality; The liquid fermenting product exists with mycelial form, does not form spore, is unfavorable for preservation and storage on the one hand, and shelf life of products is short, and mycelial effect does not have spore good yet in application on the other hand.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of strawberry specific complex successive planting resistant agent, the method for utilizing liquid spawn and solid fermentation to combine, fermentative prodn streptomyces microflavus antibiotic fertilizer has guaranteed stable and a large amount of sporulation of quality product.Nutrient uptake feature according to strawberry adds trace element; And with the microbial-bacterial fertilizer with P and K decomposing function---biological phosphorus potash fertilizer is composite; Produce multi-functional control strawberry continuous cropping sick biotechnological formulation---strawberry specific complex successive planting resistant agent, this product both can solve by the microbial continuous cropping problem of soil-borne disease, can solve the continuous cropping problem that is caused by the soil nutritional deficiency again; Simultaneously owing to added the strain of phosphorus decomposing potassium solubilizing bacteria; Formed beneficial microbe colony at plant root, improved the micro-ecological environment of soil, also phosphorus potassium nutrition element is provided for the strawberry growth.
