Special disease-prevention and root growth-promotion powdery agricultural microbial agent for strawberries, and production technology thereof

Abstract

The invention provides a special disease-prevention and root growth-promotion powdery agricultural microbial agent for strawberries, and a production technology thereof. The agricultural microbial agent comprises the following components: a carrier which is vermiculite powder; microbial thalluses which are Bacillus licheniformis, Bacillus mucilaginosus, Bacillus cereus and Streptomyces microflavus; a protection agent which comprises glycerol, skimmed milk powder, chitosan, ascorbic acid, citric acid, composite amino acid and dextrin; and an adsorbent which is weathered coal dust, wherein the microbial thalluses are bacterial sludge obtained after centrifugation and precipitation of a fermentation solution. The production technology comprises the following steps: strain activation, shakingculture, fermentation culture, bacterial sludge production, ingredient addition and aseptic packaging. The above formula is specially designed for the strawberries against the easy powdery mildew invasion problem of the strawberries according to the growth characteristics of shallow root system and large blades of the strawberries; the agricultural microbial agent has the advantages of good livingbacterium symbiosis, good stability, and realization of green blades, powdery mildew resistance and obviously enhanced stress resistance of cultivated plants; and the production technology has the advantages of simplicity, low cost, and convenience in promotion and use.

Description

technical field [0001] The invention relates to the field of agricultural microbial inoculum, in particular to a special powdery agricultural microbial inoculum for disease prevention and root promotion of strawberries and a production process. Background technique [0002] Strawberry is a perennial evergreen herbaceous plant. Its berries are bright red, fragrant and juicy, sweet and sour, and are known as the "Queen of Fruits". Strawberries are rich in nutrients and are easily digested and absorbed by the human body. They contain very rich vitamins, especially vitamin C content. Every 100 grams of strawberries contain 60 mg of vitamin C. The carotene contained is an important substance for the synthesis of vitamin A. It has the function of improving eyesight and nourishing the liver. The pectin and dietary fiber contained in it can help digestion and smooth stool. It is a healthy food suitable for all ages, especially suitable for health preservation, and is deeply loved by...

Problems solved by technology

[0004] In the field of strawberry cultivation, people mainly use chemical pesticides to prevent and control the disease. However, studies have found that powdery mildew bacteria are prone to resistance to chemical pesticides, which not only seriously damages the natural enemy biological community, but also destroys the agricultural ecological environment, and it is difficult to achieve the expected results.
