Embodiment 1

[0018] Embodiment one, the preparation of compound bacterial fertilizer:

[0019] 1) Selection of strains:

[0020] Pythium Oligandrum (Pythium Oligandrum), purchased from the Czech Biopharmaceuticals International Co., Ltd. to obtain finished preparations;

[0021] Trichoderma harzianum (Trichoderma.sp) China Agricultural Microorganism Culture Collection Management Center, strain number: ACCC30423.

[0022] 2) Trichoderma fermentation:

[0023] Biological study of Trichoderma harzianum by culture fermentation. Specific steps: cut 200g of peeled potatoes into small pieces for slope and preservation, add 1000ml of water and boil for 30min, filter out the potato pieces, make up the filtrate to 1000ml, add 20g of sucrose, 14g of agar; solid fermentation: 30% of bran, 70% of rice straw powder, K H 2 PO 4 :0.5%,(NH 4 ) 2 SO 4 :0.5%, CaCl 2 : 0.2%; material: water = 1: 2.2; culture and fermentation process at 22 ℃ for 48 hours, using mechanical stirring fermenter for fermen...

Embodiment 2

[0030] Example 2: Application effect of compound microbial fertilizer on strawberry in greenhouse

[0031] Due to the high multiple cropping index of strawberry protected cultivation, the difficulty of stubble fall, the closed environment and high humidity, the continuous cropping obstacles of strawberry production are very serious, especially the incidence of soil-borne diseases such as root rot and Verticillium wilt is high.

[0032] Ji Shi: the area of ​​the test greenhouse and the control greenhouse are both 300m 2 , the planting period is 5 years, and the incidence of soil-borne diseases is relatively serious in previous years. 2 7,000 plants were planted, and 1,500 kg of decomposed high-quality farmyard manure, 35 kg of nitrogen, phosphorus, and potassium compound fertilizer (1:1:0.5) and 40 kg of superphosphate were applied to the control shed per 667 m2. Processing greenhouse every 667m 2 Apply 1500kg of decomposed high-quality farmyard manure, 35kg of nitrogen, phos...

Abstract

The invention relates to a composite microbial bacterial fertilizer with functions of disease prevention, growth promotion and yield increase used in the crop cultivation process and application thereof. The composite microbial bacterial fertilizer comprises a fungicidal composition consisting of two microbial fungicidal strains such as pythium oligandrum and trichoderma harzianum, wherein the spore number ratio of the pythium oligandrum to trichoderma harzianum is (1:4)-(1:2). Based on the biological control principle of preparing bacteria through bacteria and the drug-fertilizer dual-effect idea, the pythium oligandrum and trichoderma harzianum with high-efficiency hyperparasitism effect on the soil-borne pathogen and a bio-fertilizer containing humic acid, amino acids and the like are proportioned and mixed, the composite microbial bacterial fertilizer with the disease-resistant and nutritive effects is developed, the functions of inhibiting and killing bacteria and increasing crop nutrition are integrated, the fertilizer is conveniently used, the manual cost is saved, and the yield and effect are increased; and moreover, the fertilizer has obvious prevention and control effects on strawberry soil-bore diseases.

Description

technical field [0001] The invention relates to a compound microbial bacterial fertilizer which is used in the special cultivation process of crops and has the functions of disease prevention, growth promotion and production increase and its application. Background technique [0002] Soil-borne diseases, viral diseases and nematode diseases are the three major intractable diseases in current crop production. In particular, soil-borne diseases cause huge yield losses to the production of economic crops such as vegetables and fruits every year, and the long-term continuous cropping of crops has caused soil-borne diseases to show a trend of increasing year by year. For soil-borne diseases, soil fumigation with chemical drugs is generally used to kill the pathogenic bacteria and achieve the purpose of disease control. Years of continuous drug treatment not only destroys the soil aggregate structure and causes soil compaction, but also its disease prevention effect is not satisf...
