Organic biofertilizer with additive and preparation method thereof

Abstract

The invention discloses an organic biofertilizer with an additive and a preparation method thereof. The organic biofertilizer comprises the following ingredients: 40 percent of human manures, poultry manures and animal slurry, 30 percent of waste material slags and 30 percent of crop straws serving as raw materials; and one part of the additive (in an account which is 0.1 percent based on the total weight of the raw materials) is added, which comprises 50 percent of composite bacterial preparation NSC-7, 2 percent of bacillus subtilis, 2 percent of bacillus cereus, 30 percent of lactobacillus, 10 percent of polyaspartic acid, 3 percent of alpha-naphthylacetic acid and 3 percent of indolylacetic acid. The preparation method comprises the following steps of: mixing the raw materials and the additive, stacking in a cement tank, fermenting for 24 hours, adding the rest additive, stirring, and continuously stacking for 2 hours; and granulating and packaging by using the technology for granulating the organic fertilizer. The organic biofertilizer with the additive has the advantages of easy material acquirement, low cost, improvement of the soil, balanced nutrition of the soil, improvement of the quality of crops, yield increase, improvement of the gain for farmers, contribution to environmental protection, wide market prospect and positive effect on the development of enterprises and agriculture.

Description

[0001] Field [0002] The invention belongs to organic fertilizers, in particular to an organic biological fertilizer with additives and a manufacturing method thereof. technical background [0003] my country is a large agricultural country. Due to the large non-cultivable area (mainly mountains, hills and deserts), the arable area is greatly reduced. In addition to the large population, the per capita arable land ranks only 126th in the world, which is the world's average per capita. 40% of the arable land area, so a large amount of food crops are imported every year to meet domestic demand. With the growth of my country's population, the development of industry and the continuous expansion of urban scale, a large amount of cultivated land is occupied, which reduces the area of ​​cultivated land year by year. The area of ​​cultivated land in the country has dropped to 1.8 billion mu, which is less than 1.4 mu per capita. There are 664 cities and counties The per capita arable...

Problems solved by technology

At present, traditional chemical fertilizers such as: nitrate nitrogen fertilizer, ammonium nitrogen fertilizer, amide nitrogen fertilizer, cyanamide nitrogen fertilizer, etc., all have a certain effect on increasing production. Due to the fast volatility and low utilization rate of this kind of chemical fertilizer, if you want to increase production, you need to apply more , this invisibly increases the burden on farmers, and at the same time, a large number of long-term use also brings many side effects, such as: pollution to the environment, groundwater and rivers and lakes are polluted to varying degrees through the infiltration of rainwater

The large-scale use of chemical fertilizers, especially nitrogen fertilizers, not only affects the performance of fertilizers, but also causes imbalances in the ratio of nitrogen, phosphorus, potassium and trace elements in the soil, soil compaction, soil fertility decline, and serious waste

More than 60% of chemical fertilizers are lost without being absorbed by crops, resulting in eutrophication of water bodies, aggravating soil erosion and increasing energy consumption
