Problems solved by technology

[0004] The purpose of the present invention is to address the characteristics of long-term large-scale and unreasonable application of chemical fertilizers, slow effect of organic fertilizers, serious shortage of application area and dosage, low efficiency of biological bacterial fertilizers, small application scale, no regional pertinence, and difficulty in marketing. To solve the problem of inconvenient mechanized application of fertilizers, we have developed a "full element" compound microbial fertilizer (granulation type) that combines the quick-acting properties of inorganic fertilizers, the long-acting properties of organic fertilizers and the synergistic properties of biological bacterial fertilizers.

Embodiment 1

[0037] 1. Decomposed cow dung common fertilizer and vegetable cakes are provided

[0038] Cow dung and rapeseed meal were purchased from the market.

[0039] 2. Production of functional bacterial agent

[0040] The rhizosphere growth-promoting Bacillus amyloliquefaciens (Bacillus amyloliquefaciens) SQR9 with the preservation number CGMCCNO.5808 was inoculated into the PDA culture medium for liquid fermentation production. The conditions for fermentation production were: the culture temperature range was 30-37°C, and the stirring speed was 170°C. ~180 rpm, spores are formed in the middle and late stages of fermentation, so that the amount of bacteria or spores in the fermentation broth is ≥1×10 9 pcs / ml; the preparation method of the PDA culture medium used is to peel 200g of potatoes, cut into small pieces and boil in water, boil for 30min, add 20g of ordinary sucrose to the filtrate after filtering, set the volume to 1000ml, and adjust the pH value Adjust to 7.0-7.6, steril...

[0049] 1. Field effect of "Quanyuan" compound microbial fertilizer on eggplant

[0050] A total of three controls were set up for one treatment, and the treatment was added with the "full element" compound microbial fertilizer (BOF) developed by the present invention, and an appropriate amount of chemical fertilizer was applied, and the control was no fertilization (CK 1 ) and the conventional amount of chemical fertilizer (CK 2 ) and inactivated "Quanyuan" compound microbial fertilizer (AOF) topdressing appropriate amount of chemical fertilizers, the test variety is black puss eggplant, except for the control without fertilization, other treatments and other nutrients. Each treatment has 3 plots, each plot is 8m long, 2.5m wide, and has an area of ​​20m 2 , apply 3kg (dry weight) "full element" compound microbial fertilizer per plot, routine management. Regularly measure the growth index of eggplant. The effects of different treatment...

Abstract

The invention provides a full-element compound microbial fertilizer and a preparation method and application thereof, and belongs to agricultural high-tech production technology. An organic fertilizer rich in Bacillus amyloliquefaciens SQR-9 (preservation number of CGMCC NO.5808) is added with 14.8% (dry weight) of ammonium sulfate to reach the total nutrient in the compound microbial fertilizer to 10%, and the mixture is granulated by a disc to obtain the fertilizer. The full-element compound microbial fertilizer (granulation type) contains total nutrients satisfying the relation of total nitrogen(TN) + total phosphorus (P2O5) + total potassium (K2O)= 0%, and after 6 months of storage, the number of functional bacteria is no less than 2*107 CFU / g of the dry weight of the fertilizer. The novel synergistic fertilizer has the quick result of fertilizer, long-acting property of organic fertilizer and synergistic function of biofertilizer, and has good growth promoting effect, low production cost and convenience for application, and can be applied to grain crops and vegetables, etc.

Description

technical field [0001] The invention belongs to the field of biological fertilizers, and relates to a "full element" compound microbial fertilizer and its preparation method and application. Background technique [0002] Some developed countries entered the stage of agricultural modernization in the 1920s, and my country entered the stage of agricultural modernization in the 1960s, adopting the conventional agricultural modernization development model of "high input, high output, and high pollution", which greatly improved the level of agricultural production. At the same time, it has also led to extreme consumption of resources, serious damage and pollution of the ecological environment. With the development of the chemical fertilizer industry and the increase in the application of agricultural chemical fertilizers, the output of crops has greatly increased. However, while chemical fertilizers have made great contributions to the development of agricultural production, they...
