Method for making biological organic fertilizer by using rice straws as main raw material

Abstract

The invention relates to a making technology of a biological organic fertilizer, which belongs to the field of crop straw deep processing, and in particular relates to a method for making the biological organic fertilizer by using rice straws as a main raw material. More specifically, rice straws are adopted as the main raw material; animal wastes and pond sludge are adopted as auxiliary materials; and the main raw material and the auxiliary materials are fermented by EM (Effective Microorganism) strain, which is enlarged in multiple stages, so as to obtain the biological organic fertilizer. The method for making the biological organic fertilizer by using rice straws as the main raw material, provided by the invention, has the advantages of wide raw material source, low price, simple product making process and high beneficial bacteria content in the formed product as well as has the characteristics of increasing soil organic matter, improving the soil structure, promoting the soil microbial activities, enhancing the soil fertility keeping and fertility supplying properties and the like; and the crop yield is also obviously increased, the crop quality is improved and the fertilizer input can be reduced in the product application; therefore, the production cost is reduced and the farmer income is increased.

Description

technical field [0001] The invention relates to a production technology of bio-organic fertilizer, which belongs to the field of deep processing of crop stalks, and in particular relates to a method for making bio-organic fertilizer with rice stalks as the main raw material. Background technique [0002] Rice is the main food crop in southern my country. The theory of large grain industry holds that: food crops are composed of fruit and straw, and the fruit eaten by humans is only 20% of the weight of the crop, and the remaining 80% of the straw is inedible; therefore, rice straw resources are very rich. At present, the utilization rate of rice straw is very low, and most of the treatment methods are returned to the field through incineration; although some are crushed and returned to the field, the utilization rate is quite low, and a lot of organic matter is lost, and it is returned to the later planting Bring a lot of trouble; Also have to pile up and let it rot, it will...

AI Technical Summary

Problems solved by technology

At present, the utilization rate of rice straw is very low, and most of the treatment methods are returned to the field through incineration; although some are crushed and returned to the field, the utilization rate is quite low, and a lot of organic matter is lost, and it is returned to the later planting It brings a lot of trouble; there are also piles left to rot, and it takes a long time for the rice to rot naturally without any technical measures

The process of burning rice straw is simple and easy, but the utilization rate of rice straw is relatively zero, and it will also cause a large number of social, economic and ecological problems such as air pollution, soil mineralization, and fire accidents.
