Biogas liquid fertilizer with function of increasing sugar contents of sweet potatoes

Abstract

The invention belongs to the field of technologies for cultivating sweet potatoes, and particularly discloses a biogas liquid fertilizer with a function of increasing sugar contents of sweet potatoes.The biogas liquid fertilizer comprises, by weight, 110-120 parts of livestock poultry biogas liquid, 18-20 parts of folium mori juice, 1.2-1.4 parts of streptomyces albovinaceus, 5.2-5.8 parts of citric acid chelated copper, 2.1-2.5 parts of citric acid chelated manganese, 0.6-0.8 part of algal polysaccharides and 4.4-4.8 parts of wood vinegar. The biogas liquid fertilizer has the advantages thatthe biogas liquid fertilizer can be applied to sweet potato planting lands, accordingly, soil in the sweet potato planting lands can be effectively activated, the content of microorganisms in the soil can be increased, the water and air permeability of the soil can be improved, quick and robust growth of rhizomes and synthesis and accumulation of nutrient substances of tubers can be promoted, particularly, synthesis and accumulation of sugar can be effectively promoted, and taste of the sweet potatoes can be greatly improved; the content of chlorophyll in the sweet potatoes can be effectivelyincreased, the photosynthesis efficiency of the sweet potatoes can be improved, the metabolic capacity of sweet potato plants can be improved, accordingly, growth and development of the tubers can beeffectively promoted, and the yield of the tubers can be increased.

Description

technical field [0001] The invention belongs to the technical field of sweet potato cultivation, in particular to a biogas slurry fertilizer for increasing the sugar content of sweet potatoes. Background technique [0002] With the rapid development of my country's intensive livestock and poultry breeding industry, the discharge of livestock and poultry biogas slurry has increased. It is rich in high-concentration organic pollutants and N, P and other components, and the pollution load is very high. If it is not properly treated, it will cause pollution. The surrounding soil, surface water and groundwater bring harm and become a source of pollution that cannot be ignored; how to effectively treat and comprehensively utilize livestock and poultry biogas slurry to achieve reduction, resource utilization and harmlessness is the key to ensuring my country's livestock The poultry farming industry continues to flourish and needs to be solved urgently; livestock and poultry biogas sl...

[0002] With the rapid development of my country's intensive livestock and poultry breeding industry, the discharge of livestock and poultry biogas slurry has increased. It is rich in high-concentration organic pollutants and N, P and other components, and the pollution load is very high. If it is not properly treated, it will cause pollution. The surrounding soil, surface water and groundwater bring harm and become a source of pollution that cannot be ignored; how to effectively treat and comprehensively utilize livestock and poultry biogas slurry to achieve reduction, resource utilization and harmlessness is the key to ensuring my country's livestock The poultry farming industry continues to flourish and needs to be solved urgently; livestock and poultry biogas slurry contains a large amount of organic matter, nitrogen, phosphorus, potassium and trace elements and other nutrients needed for crop growth, and can be used as a valuable agricultural resource to participate in crop planting In the process, but direct application is not conducive to direct absorption by crops. In addition, it is easy to block soil pores, reduce soil water permeability and air permeability, deteriorate soil quality and even cause crop yield reduction

[0003] Sweet potatoes are often eaten in people's daily life, and are widely planted in various parts of our country, but the sweet potatoes sold in the market often have low sweetness and low sugar content, resulting in poor taste of sweet potatoes, which makes the sales of sweet potatoes Therefore, the use of livestock and poultry biogas slurry in sweet potato production to increase the sugar content of sweet potato and improve its taste will not only effectively improve the utilization rate of livestock and poultry biogas slurry, reduce environmental pollution, but also promote the rapid development of the sweet potato industry. development and increase the economic benefits of growers
