Preparation and application methods of special selenium-enriched nutrient fertilizer for tetrastigma hemsleyanum

Abstract

The invention discloses preparation and application methods of a special selenium-enriched nutrient fertilizer for tetrastigma hemsleyanum. The preparation method uses waste stem leaves obtained in the process of artificial planting and processing of the tetrastigma hemsleyanum, sugar, seaweed, sea trash fish meal and whole wild tetrastigma hemsleyanum plants and water as raw materials, seal fermentation is performed to obtain a base liquid, and a specific ratio of alpha-naphthalene acetic acid, water-soluble chitosan, a selenium-rich nutrient solution and casein hydrolysate which are favorable for promoting the growth and development of the tetrastigma hemsleyanum are added into the base liquid, and therefore the special selenium-enriched nutrient fertilizer for the tetrastigma hemsleyanum is prepared; the nutrient fertilizer has a high selenium content, rich nutrients and no chemical fertilizers, contains specific symbiotic bacteria of roots of the whole wild tetrastigma hemsleyanumplants, is in line with the nutrient absorption and growth characteristics of the tetrastigma hemsleyanum, can promote growth of the tetrastigma hemsleyanum plants and greatly increase the yield and the content of medicinal active ingredients of the tetrastigma hemsleyanum, and makes the tetrastigma hemsleyanum rich in selenium, thereby realizing production and efficiency increase of the tetrastigma hemsleyanum; and the preparation and application methods disclosed by the invention are simple and practical, and have strong operability and low costs, thereby facilitating practical promotion andapplication.

Description

technical field [0001] The invention belongs to the field of biotechnology, in particular to a method for preparing and applying a special selenium-enriched nutrient fertilizer for trifoliate greens. Background technique [0002] Clover, also known as golden thread hanging gourd and snake monkshood, belongs to the herbaceous vine of Rhamnaceae Vitiaceae, and is a rare medicinal plant in my country. Wild clover is mainly distributed in Zhejiang, Jiangxi and other places. It is mainly used as medicine with spherical roots. The main active ingredients contain flavonoids, flavonoids, vitamins, amino acids and other ingredients. It is used to treat febrile convulsions, pneumonia, asthma, hepatitis, rheumatism, irregular menstruation, sore throat and other diseases. Modern pharmacological studies have proved that Clover has anti-virus, anti-inflammatory, analgesic, antipyretic, liver-protecting, anti-tumor effects, and has no side effects and no drug resistance. It is called "pla...

AI Technical Summary

Problems solved by technology

[0003] At present, the artificial planting technology of cloverleaf has been basically successful, but due to the growth characteristics of cloverleaf, the growth is extremely slow, and it can only be harvested in 3 to 5 years. The yield is low, and there are still many problems in the promotion of cultivation. The main manifestations are: First, a large amount of nitrogen and potassium fertilizers are used in the traditional planting process. Although the growth can be promoted to a certain extent in the early stage, as the cultivation years increase, secondary salinization and acidification of the soil caused by excessive fertilization will directly affect the growth rate of tubers. ; The second, continuous planting makes harmful substances in the soil gradually accumulate, causing the output of Clover to decrease year by year, active ingredients such as total flavonoid content, etc. show a downward trend, and the quality gradually declines; The planting enthusiasm of households has been greatly reduced, which seriously affects the rapid development of the Clover industry
