Abstract

The invention relates to a tobacco planting soil improving agent and a preparation method thereof, and belongs to the technical field of soil improvement. The method comprises the following steps: using soybean nodules as a matrix, crushing and collecting a rhizobia suspension, by combining the rhizobia suspension with a lichen extract, coating the rhizobia with the lichen extract, effectively coating and effectively fixing nitrogen in the soil, and improving the fertility of the tobacco planting soil and providing favorable conditions for soil improvement. The lichen extract is used as a mainbody of the improving agent to be sprayed on the improved soil to allow nutrients to be loaded to the soil surface layer, thereby promoting the plants to rapidly absorb the nutrients in the lichen extract; the nodules and rhizobia formed by plants can use the free nitrogen in the air to synthesize ammonia, thereby promoting the plant rhizosphere development, increasing soil biomass quantity, andimproving soil fertility.

Description

technical field [0001] The invention relates to a tobacco planting soil improver and a preparation method thereof, belonging to the technical field of soil improvement. Background technique [0002] Tobacco, Nicotiana genus Solanaceae, first originated in America and was introduced to China around the 16th century. Tobacco, as a special foliar economic crop with high economic value, plays an important role in my country's national economy. my country's smoking areas are distributed in 24 provinces (autonomous regions and municipalities) including Yunnan, Guizhou, Sichuan, Hunan, and Henan. According to statistics, in 2014, there were 110 prefectures and cities, 527 counties (cities), 4952 townships, 39092 villages, 1.66 million households planted tobacco leaves, the tobacco planting area was 18.37 million mu, and 46.5 million tons of tobacco leaves were purchased. Tobacco farmers earn about 60 billion yuan from tobacco sales, with an average income of 36,200 yuan per house...
