Method for rice straw treatment by using grass carp culture

Abstract

The invention discloses a method for rice straw treatment by using grass carp culture, which belongs to the technical field of straw treatment. The method for rice straw treatment by using grass carp culture needs to take grass carp fry with fish feed for breeding. After breeding, grass carps are fed by grass carp feed prepared by rice straw. Then the amount of the feed is adjusted in different growth stages. Next the grass carp feed and rice straw are mixed to fed grass carp and the proportion of rice straw is constantly adjusted until grass carps can completely eat rice straw for a living. Survival grass carps are collected into rice straw field for breeding. The grass carps bred by the method eat rice straw as food. The breeding method, according to local conditions, local materials, carries out comprehensive utilization, which can not only solve the problem of insufficient fish feed, but also solve the difficult problem of rice straw returned, with comprehensive economic benefits.

Description

technical field [0001] The invention discloses a method for treating rice straw by using cultured grass carp, and belongs to the technical field of straw treatment. Background technique [0002] The annual output of crop straw in China is about 700 million tons, and it is one of the countries with abundant straw resources. For a long time, straw has not been effectively utilized as a resource, and a large amount of straw has been discarded and burned, which not only leads to a large waste of organic matter and nutrient resources, but also And it will cause serious environmental pollution. Production practice in my country for many years has proved that returning straw to the field can effectively increase the content of soil organic matter, improve soil and fertilize soil fertility. However, the ratio of C and N in the soil is high, so it is not easy to rot, and often due to excessive overturning and insufficient soil moisture, it will hinder cultivation and affect seedling...

Problems solved by technology

[0005] The technical problem mainly solved by the present invention: in view of the large amount of rice stalks in our country at present, in the mechanized return of rice stalks, the amount of rice stalks is large, the efficiency of returning to the field is slow, the rice stalks are not easy to degrade, and in the freshwater culture of grass carp, the source of bait is insufficient The problem is becoming more and more prominent, providing a method of cultivating and domesticating grass carp to obtain grass carp that can eat rice stalks, and putting them into rice straw fields to cultivate and process the stalks. Breeding, feeding grass carp feed prepared by rice straw after breeding, adjusting the amount of feed at different stages of growth, and then feeding grass carp feed mixed with rice straw, and continuously adjusting the ratio of rice straw until the grass carp is fed with rice straw. The grass carp that has survived is collected and put into the rice straw field for breeding. The grass carp obtained from the cultivation of the present invention feeds on edible rice straw. , and can solve the problem of rice straw returning to the field, and has comprehensive economic benefits
