Microalgae nutrition repair liquid for relieving grassland desertification

Abstract

The invention discloses a microalgae nutrition repair liquid for relieving grassland desertification, which comprises a microalgae mixed liquid, the microalgae mixed liquid comprises seven active microalgae, and the added microalgae comprises the following components in parts by weight: 5-40 parts of hylothrix tadeeri, 5-40 parts of hylothrix wonderi, 10-50 parts of microcoleus vaginalis, 5-40 parts of pseudocladoidea, 10-50 parts of monofidus microfidus and 30-80 parts of chlorella pyrenoidosa, and the microalgae mixed liquid comprises the following components in parts by weight: 5-40 parts of hylothrix tadeeri, 5-40 parts of hylothrix wonderi, 10-50 parts of microcoleus vaginalis and 30-80 parts of chlorella pyrenoidosa. In addition, 10-50 parts of nitrogen-fixing anabaena or 20 parts of cotton algae are selected to be added. Aiming at the grassland desertification region, the nutrient restoration liquid can restore soil, supplement natural nitrogen, activate soil trace elements, improve plant stress resistance and prevent plant diseases and insect pests, the seven microalgae have good compatibility, the number of microalgae active cells in each 1mL of the nutrient restoration liquid can reach more than 106, and the nutrient restoration liquid has good application prospects. The storage life of the nutrient repair liquid reaches 18 months, the culture process is obtained through a large number of experiments, and the culture efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of desertification prevention and control, in particular to a microalgae nutrient repair solution for relieving grassland desertification. Background technique [0002] At present, two-thirds of the world's countries and regions face the threat of desertification, which seriously affects the living space and sustainable development of human beings. Desertification has become an ecological and environmental issue of global concern. In desertified areas, land is degraded, productivity declines, surface wind erosion and sandification, sand dunes move and bury farmland, roads, and houses, the ecology is fragile, the economic conditions are relatively backward, and prevention and control are very difficult. [0003] Improving the vegetation environment is an important means to prevent desertification, such as afforestation, grass breeding and grass cultivation. However, the soil in desertified areas is poor, the...

AI Technical Summary

Problems solved by technology

However, the soil in desertified areas is poor, and the nutrients that can provide vegetation are seriously lacking, the survival rate of vegetation is low, and the control effect is not good.

The application of chemical fertilizers can improve the survival rate of vegetation to a certain extent, but the negative impact of chemical fertilizers cannot be ignored: the raw materials for the production of chemical fertilizers contain heavy metals such as Zn, Cu, Co, and Cr, and these heavy metals are added to the plant following chemical fertilizers. soil, and cause the enrichment of heavy metal elements in the soil, which enter the plant through plant absorption and affect plant growth; chemical fertilizers will reduce the number and activity of soil microorganisms, thereby reducing the conversion of soil microorganisms to organic matter in the soil, the decomposition of minerals and Degradation of toxic substances; long-term application of chemical fertilizers will aggravate soil acidification, aggravate soil compaction, inhibit plant root development, and seriously reduce plant stress resistance
