Abstract

The invention discloses a method for root rot resistance and growth promotion of rhodiola rosea through biological prevention and control. The method includes the following steps that a high-density bacterium suspension with the density of 10<9> cfu / mL-10<10> cfu / mL is prepared through bacillus subtilis; healthy branches of rhodiola rosea are cut into small sections for composting, the high-density bacterium suspension of bacillus subtilis is sprayed in the composting process, biological fertilizer capable of effectively restraining and killing rhodiola rosea root rot disease bacteria is obtained after fermentation, and the biological fertilizer is applied to root rot resistance and growth promotion of rhodiola rosea through biological prevention and control. According to the method, bacillus subtilis producing beta dextranase is plant probiotics playing a role in disease resistance and growth promotion of rhodiola rosea, bacillus subtilis is added to compost, the restraining and killing effects on rhodiola rosea root rot disease bacteria are remarkably improved, and the fresh root weight of rhodiola rosea is remarkably increased. Treatment is simple and convenient in the composting process, no wastewater is discharged, investment is small, energy consumption is low, operation is easy, industrial large-scale production is facilitated, and good economic benefits and wide application prospects are achieved.

Description

technical field [0001] The invention relates to the field of preparation of biological control fertilizers, in particular to a method for biological control of rhodiola root rot and growth promotion. Background technique [0002] Rhodiola rosea (scientific name: Rhodiola rosea L.) is a perennial herb with a height of 10-20 cm. The roots are thick, conical, fleshy, brownish-yellow, with many fibrous roots at the root neck, short, thick, cylindrical rhizomes, covered with many scale-like leaves arranged in tiles, growing in the alpine and pollution-free zone at an altitude of 1800-2500 meters , its growth environment is harsh, so it has strong vitality and special adaptability. Rhodiola rosea can be used as medicine, it can invigorate qi and clear the lungs, improve intelligence and nourish the heart. It is a traditional Chinese medicine with a wide range of functions, and it also has cosmetic effects. It can be used as skin care products and can also be eaten. Rhodiola root...
