A kind of low-temperature phosphate-dissolving Sinorhizobium and bacterial agent thereof

Abstract

The invention relates to a low-temperature phosphorus-dissolving Sinorhizobium sp. and its bacterial agent. The strain name is ATHC‑2, and the classification name is Sinorhizobium sp.. The depository unit is the General Microbiology Center of China Microbiological Culture Preservation Management Committee. The number is CGMCC No.10651, the preservation date is: March 20, 2015, and the preservation address is: No. 3, Yard No. 1, Beichen West Road, Chaoyang District, Beijing. The bacterial strain ATHC-2 of the present invention can withstand the influence of low temperature on its growth, and has strong phosphorus-dissolving activity. The impact of low temperature stress on soybean nodulation and nitrogen fixation in agricultural production can be alleviated by applying low temperature resistant rhizobia agents, improving soil fertility, reducing the use of chemical fertilizers, and improving the yield and quality of soybeans and other crops.

Description

technical field [0001] The invention belongs to the fields related to planting and fertilizers, and relates to a low-temperature phosphate-dissolving Sinorhizobium and its agent. Background technique [0002] my country's agricultural production has long adopted a development model of high input and high output, resulting in a heavy reliance on chemical fertilizers in agricultural production. Extensive use of chemical fertilizers not only increases the cost of agricultural production, but also tends to cause soil compaction, resulting in reduced crop yields. A large amount of unused nitrogen, phosphorus, potassium and other nutrients enter the ecological environment such as groundwater and rivers with rainfall, resulting in eutrophication of river water, ecological imbalance and environmental pollution, posing a threat to the sustainable development of agriculture. [0003] Biological nitrogen fixation can improve crop yield, fertilize the soil and maintain the balance of t...
