A special biological organic fertilizer for organic tea and preparation method thereof

Abstract

The invention discloses special bio-organic fertilizer for organic tea and a preparation method of the special bio-organic fertilizer, and solves the problem of lack of appropriate and special fertilizer for organic tea planting in Guizhou province. The special bio-organic fertilizer for organic tea comprises the following components in percentage by weight: 25-35 percent of distiller grains, 15-25 percent of Chinese herb residue, 30-40 percent of chicken manure, 4-6 percent of mineral substance powder, 0.01-0.03 percent of a microbial agent I, 10-20 percent of a conditioner and 0.1-5 percent of a microbial agent II. The invention further provides the preparation method of the special bio-organic fertilizer for organic tea. According to the invention, abundant organic waste resources of Guizhou province are utilized, various nutrients are provided for the growth of organic tea, the improvement on the soil structure and the fertilizer utilization rate is facilitated, and the yield and the quality can be increased remarkably; and meanwhile, the cyclic utilization of organic waste is realized, the fertilizer preparation cost is low, and favorable economic benefits and ecological environment benefits are achieved.

Description

technical field [0001] The invention relates to a special bio-organic fertilizer for organic tea and a preparation method thereof. The invention belongs to the technical field of fertilizers and preparation methods. Background technique [0002] In 2013, the total area of ​​tea gardens in Guizhou Province reached 6.11 million mu, accounting for 15.8% of the total area of ​​tea gardens in China, ranking first in the country. The province's tea gardens that have passed pollution-free, green, and organic certifications amount to 893,300 mu, including 163,500 mu of organic tea gardens, ranking second in the country. Guizhou Province has unique natural conditions for establishing organic tea gardens. Guizhou is the only tea producing area in the country with low latitude, high altitude, and little sunshine. It is the original place of tea trees and one of the ancient tea areas. The sandy soil with coal seams is deep and rich in selenium, zinc, potassium, strontium, germanium an...

Problems solved by technology

[0003] At present, there are two major technical problems in the nutrient management of organic tea gardens in Guizhou: one is the problem of the efficiency of organic fertilizers. The nutrient content of the fertilizer is low, there are many impurities, and the content is extremely unstable, so the nutrient content and effect of application cannot be guaranteed

The nutrient management of tea gardens is backward and the soil is compacted, resulting in low tea yield per unit area and unstable quality, which has become the main factor restricting the development of organic tea industry in Guizhou

The second is the problem of harmless organic fertilizers. Industrial production of organic fertilizers lacks simple and easy farmyard manure harmless treatment technology. Commercial organic fertilizer manufacturers also try to use organic materials from other sources to prepare organic fertilizers, but the fermentation method is mostly to add The method of mixing one-time fermentation in poultry manure cannot effectively utilize the nutrient characteristics of different materials, the material ratio is unreasonable, the composting time is long, the nutrient loss is large, and the organic fertilizer produced is low in fertilizer efficiency, which cannot meet the nutrient requirements of organic tea. need

According to statistics, the annual output of Maotai-flavored liquor lees in Maotai Town and Chishui River reaches 3 million tons, which is large and concentrated. If it is not handled in time, it will deteriorate, not only wasting precious resources, but also seriously polluting the surrounding environment.

Disadvantages of sorghum fermented waste distiller’s grains for fermentation materials are fermented fillers such as rice husks that are not easy to use, high water content (>65%) when the grains are produced, and rich in crude fiber substances, which require special bacteria for fiber substances agent
