Microbial fertilizer special for tobaccos, and preparing method thereof

Abstract

The invention provides a novel microbial fertilizer special for tobaccos. The fertilizer comprises the following components in parts by weight: 5 to 25 parts of a complex microbial inoculant and 75 to 95 parts of a carrier, wherein the complex microbial inoculant contains 1.6 to 8 hundred million cfu/g of bacillus subtilis, 1.6 to 8 hundred million cfu/g of bacillus licheniformis, 0.4 to 2.0 hundred million cfu/g of trichoderma harzianum and 0.4 to 2.0 hundred million cfu/g of calicheamicin streptomyces hygroscopicus; the carrier is a powdered material which are made by performing microbe fermentation and decomposition on rape seed cakes, bean pulp cakes and sesame-seed cakes, and then performing drying and sieveing. The microbial fertilizer contains bacterial strains for antagonizing fungus pathogenic bacteria, bacterial strains for preventing and curing the breeding of soil pathogenic bacteria, bacterial strains for improving the soil environment and the like. The carrier is fermented three-cake fertilizer. The invention also provides a preparing method for the microbial fertilizer. The microbial fertilizer special for the tobaccos, provided by the invention, is powder, is capable of absorbing the water and preserving the moisture. The fertilizer is mainly used as the base fertilizer when fertilizing, the soil fertility can be improved, the nutrient absorption of crops is improved, the diseases of a plurality of crops can be prevented, and the quality and the yield of tobacco leaves can be effectively improved.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a special microbial fertilizer for tobacco and a preparation method thereof. Background technique [0002] Agriculture is the basic industry of the national economy, and the development of agriculture is related to the overall situation of the national economy. At the same time, agricultural production has a long cycle and is greatly affected by the objective environment. Therefore, the state attaches great importance to the development of agriculture, and the approval of units engaged in agricultural technology research, development, production and operation often has to go through a long process. Hunan Taigu Biotechnology Co., Ltd. has already started to engage in the research and development of related agricultural microorganisms before the official establishment of the Agricultural Microbiology Research Institute. [0003] Hunan is a large tobacco leaf producing provi...

Problems solved by technology

For a long time, due to the extensive use of chemical fertilizers, chemical pesticides and fungicides in agricultural production, the soil structure has been continuously damaged, soil organic matter has not been replenished, and the soil micro-ecological environment has lost balance, resulting in serious soil compaction and poor water retention capacity. Greatly reduced, soil pathogenic microorganisms reproduce in large numbers, especially the tobacco planting ind...
