Embodiment 1

[0034] 1. Sources of decomposed pig manure common fertilizer and rapeseed meal compost: qualified pig manure organic fertilizer (Changsha Lvfengyuan Bio-Organic Fertilizer Co., Ltd. "Volvo" brand) and rapeseed meal compost (Chongqing Yuyan Organic Fertilizer Co., Ltd.) products Obtained by market purchase.

[0035]2. Production of functional bacterial agent: inoculate the rhizosphere growth-promoting Bacillus amyloliquefaciens (Bacillus amyloliquifaciens) T-5 with the preservation number CGMCCNO.8547 into the PDA culture medium, and carry out liquid fermentation production. The temperature range is 28-37°C, the stirring speed is 180 rpm, and spores are formed in the middle and late stages of fermentation, so that the total amount of active bacteria and spores in the fermentation broth is ≥1×10 9 CFU / mL; The PDA culture medium used is prepared as follows: Peel 200g of potatoes and cut them into small pieces, put them in 500mL of water, heat and boil for 30min, add 20g of sucros...

[0044] 1. Application effect of multiple bio-organic fertilizers on tomato

[0045] 3 treatments are arranged altogether, wherein contrast treatment 3, handle and add " multivariate bio-organic fertilizer " (TR) top dressing of the present invention develops and apply appropriate amount of chemical fertilizers, contrast is the chemical fertilizers (CK2, urea: Hunan Yihua Chemical Co., Ltd., Zijiang brand; compound fertilizer: Hubei Zhongfu Chemical Group Co., Ltd., Xinxinfu brand. All applied according to the amount recommended by the manufacturer.), the test variety is Xiangtomato No. 3, except for the control without fertilization , and the nutrients of other treatments were adjusted to be consistent. Each handles 3 plots, each plot area is 16 square meters, the width of the ditch is 1.2m, the row spacing is 50cm, the plant spacing is 50cm, 52 strains per plot, and each plot uses 4kg (dry weight) "multivariate bio-organic fertilizer", c...

Abstract

The invention provides multielement biologic organic fertilizer which comprises monoammonium phosphate, potassium sulphate, ammonium sulfate and an organic fertilizer body. The organic fertilizer is obtained by mixing rotten pig manure compost, rapeseed meal compost and hydrolyzed starch bacillus bacterial strains and then conducting solid fermentation on the mixture. The invention further provides preparing method and application of the multielement biologic organic fertilizer. According to the multielement biologic organic fertilizer, the total nutrient can reach over 10%, and the number of active microbial strains is equal to or larger than 2*10<7> CFU / g (dry weight of the fertilizer) within 6 months of storage of the fertilizer. It is verified by field fertilizer efficiency that the novel fertilizer is very good in effect, the product cost of the compound microbial fertilizer is greatly lowered through the production technology, the technology is simple, the fertilizer efficiency is remarkable, and the fertilizer can be applied and popularized in a large area.

Description

technical field [0001] The invention relates to the field of agricultural biotechnology, in particular to a multi-component biological organic fertilizer and a preparation method thereof. Background technique [0002] At present, my country consumes nearly 60 million tons of chemical fertilizers of nutrient resources every year, accounting for about 30% of the world's total consumption of chemical fertilizers. The utilization rate of chemical nitrogen fertilizers is only 30%, and the loss rate is as high as 60%, which greatly consumes non-renewable resources used for chemical fertilizer production. In my country, due to the long-term excessive application of chemical fertilizers, and the lack of scientific fertilization, especially chemical nitrogen fertilizers; and organic fertilizers due to their slow effectiveness, the amount of application and the application area are seriously insufficient; the resources of efficient microbial strains in bio-organic fertilizers are lacki...
