Biological strain prepared from rice straw and rice husk serving as main raw materials

Abstract

The invention relates to a biological strain. Rice straw and rice husk are used as main raw materials, corn powder and chitin are used as auxiliary materials to prepare a culture medium; soybean milkand brown sugar are used as a nutritional solution, and EM bacteria is used as a bacterial source to prepare a bacterial solution; and the culture medium is fermented into the biological strain by using the bacterial solution. In the implementation process of the invention, the rice straw and the rice husk are used as the main raw materials, the corn powder and the chitin are used as the auxiliarymaterials, and the soybean milk and the brown sugar are used for preparing the nutritional solution, so that the prepared culture medium is rich in nutrition; the culture medium preparing from the rice straw and the rice husk is loose in structure, so that when the EM strain is proliferated, the EM strain can be multiplied at multiple levels in a short time, the fermentation effect is 3 to 5 times of that of the traditional method, and the strain is vigorous in growth and high in vitality. By adding the chitin in the implementation process, the formed biological strain not only has the efficacy of the biological strain, but also has the advantages and functions of the chitin.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a biological strain prepared from rice straw and chaff as main raw materials. Background technique [0002] Rice is the main food crop in southern my country. The theory of the big 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 take a long time to make the rice rot naturally without any technical measures. The process of burning...

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.
