Description

Method for preparing bio-organic fertilizer by using ampullaria gigas powder

Technical Field

The invention relates to the technical field of biological organic fertilizers, in particular to a method for preparing a biological organic fertilizer by using ampullaria gigas powder.

Background

The utilization rate of chemical fertilizers in China is not high, and the utilization rate of nitrogen fertilizers in the season is only 35%. According to the data of food and agricultural organizations in the united nations, the fertilizer consumption in China from 1980 to 2002 is increased by 61%, and the grain yield is only increased by 31%. The low fertilizer utilization rate is always a problem in agricultural fertilization in China. The disadvantages brought by applying the fertilizer for a long time are as follows: (1) heavy metals and toxic elements are increased; (2) the microbial activity is reduced, and substances are difficult to convert and degrade; (3) nutrient imbalance, nitrate accumulation; (4) acidification is aggravated and pH changes too much.

The total quantity of agricultural resources which are relied on by agricultural development in China is in the forefront of the world, but the per-capita occupation is greatly lower than the average level in the world, and is increasingly reduced, and the prospect is worried, for example, the total cultivated land area in China is 15 hundred million mu, but the per-capita cultivated land area is less than 1.2 mu, which is only equivalent to 1/3 of the average level in the world; the total amount of water resources is 2.8 trillion m when the whole year is cultivated in less than 2700m, which is 1/4 which is the same as the whole world.

Therefore, cultivated land and water resources are in shortage in China; while agricultural culture is the foundation and core of traditional Chinese culture, for a long time, due to policy guidance and survival pressure, farmers keep sustainable fertility of the land by adding farmyard manure, plant ash and the like, and at present, the high yield of agricultural production is maintained by a method of applying a large amount of inorganic fertilizer, which only means the progress of land skimming skills, but actually the farmers do not care about the productivity of the land, and the relation between the farmers and the nature is more and more tense. There is a need to develop a fertilizer that can replace inorganic fertilizers.

Therefore, the bio-organic fertilizer is gradually valued by people; the biological organic fertilizer is a fertilizer which is prepared by compounding specific functional microorganisms and organic materials mainly prepared from animal and plant residues (such as livestock and poultry manure, crop straws and the like) or shells and subjected to harmless treatment and decomposition. Compared with the common organic fertilizer, the technical content of the production of the biological organic fertilizer is relatively high, except that the biological microbial inoculum for promoting the decomposition and decomposition of organic materials is added in the decomposition process to realize the purposes of directional decomposition, deodorization and the like, and microorganisms with specific functions are added in the product to improve the action effect of the product. In 2010, more than 120 production enterprises obtaining product registration certificates in Ministry of agriculture achieve 200 million tons per year, and have a certain production scale; to date, the scale of production has changed day by day.

For example, Pomacea canaliculata has strong environmental-adaptive viability and can quickly reproduce, so that the Pomacea canaliculata can be rapidly diffused in rivers, lakes and fields; the food intake is large, the variety of food is large, the growth of grain crops, vegetables and aquatic crops can be damaged, and the food becomes harmful animals in places such as Guangdong, Guangxi, Fujian, Yunnan, Zhejiang, Shanghai, Jiangsu and the like. Particularly in paddy fields, the propagation is fast, great harm is caused to paddy rice, and how to effectively utilize the ampullaria gigas is a continuous improvement on the prior art.

Clock XX, Guest City Wuxuan county, sugarcane farmers, planting sugarcane at home for 20 mu; beginning to apply the bio-organic fertilizer to plant sugarcane in beginning spring of 2015, and applying fertilizers twice in the whole growth period of the sugarcane, namely base fertilizers and additional fertilizers; the total amount of the fertilizer applied in the two times is half of that of the fertilizer applied without the biological organic fertilizer; the price of the fertilizer rises year after year, so that the planting cost of farmers is greatly increased; the bio-organic fertilizer has low price, so that the planting cost of farmers is greatly reduced; the sugarcane has good growth vigor, thick and strong rootstocks, no diseases such as sugarcane pineapple disease, sugarcane smut, brown stripe disease, shift disease and the like, and no lodging phenomenon of the sugarcane; the sugarcane is harvested to the end of 2015, the total harvested sugarcane is 160.8 tons, and the total harvested sugarcane in 2014 is 112.8 tons, and the increment is 48 tons; the yield improvement amount is more than 42.6 percent, and the income is increased by 25248 yuan compared with 2014 according to the local current year that the price of the sugarcane is 526 yuan/ton; brings great economic benefit to farmers.

Wer XX, 10 mu of oyster mushroom is planted in Wuxuan county in guest city, and farmers plant mushrooms in 2015, apply the bio-organic fertilizer for 2 times, and have good mushroom growth vigor compared with 2014; the mushroom yield is high, large and uniform; the amount of mushrooms harvested in 2015 in the same year is 38545.8 jin, while the amount of peanuts in 2014 in 30282.3 jin, and the yield is increased to 8263.5 jin in 2015 compared with that in 2014; brings great economic benefit for farmers.

According to the method, 10 mu of corn is planted in the season XX, people in the Guest city, Wuxuan county, farmers at home, the corn is planted in 2015, the bio-organic fertilizer is applied for 2 times, and compared with 2014, the corn grows well and leaves are green; the corn has large fruiting amount, large, full and uniform; the corn quantity harvested in the same year in 2015 is 32566.6 jin, the peanut quantity in 2014 is 28632.3 jin, and the yield is increased to 3934.3 jin in 2015 compared with 2014; brings great economic benefit for farmers.
