dc.description.abstract | Based on the current situation that the annual amount of agricultural straw in China is more than one billion tons, this research paper deeply discusses the problems of agricultural straw in China, and then uses the concept of circular economy to seek solutions, so as to seek the recycling of rice straw residues in agricultural rice production process. In this paper, we not only use the rubbing and brooming rice straw as the seedling substrate , but also use the modular straw substrate board to replace the complex seedling soil preparation process, so as to reduce the labor demand and operation cost of the rice seedling process. The paper uses the core material of this research-- rubbing and brooming rice straw, which has good acid retention and acid control physical and chemical performance and provide a more long-term acidic environment than the traditional seedling soil to provide the conditions for the growth and development of rice seedlings, and this acidic environment can also inhibit rice seedling blight in the northeast cold region in terms of plant pathology.
In the latter part of the study, the rubbing and brooming rice straw was introduced into the standard operating procedure of rice seedling raising, and the analysis showed that the operation cost of rice straw substrate used in rice seedling raising was lower than that of traditional seedling raising soil. If SD agricultural company can continue to expand the advantages of straw raw materials, deepen the advantages of patent process, and make the advantages of the basic scale market according to the SWOT analysis results, and solve the problem of rice industry demand, and obtain the national policy award on circular economy, so as to set up the agricultural circular economy demonstration park, then the complete agricultural circular economy can be realized. | en_US |
