High production techniques for hybrid rice
High production techniques for hybrid rice
Mixed rice is a food crop of high yield and nutritional value and is an important source of food supplementation and development. Effective increases in rice production are important not only for ensuring national food security and food availability, but also for achieving sustainable development of plants and agriculture。
At present, there has been considerable progress in research on the use of hybrid rice technologies, based on technological innovations, technological transformations, counter-resilientness and quality in production, and the establishment of high-yield cultivation systems for hybrid rice. Effectively exploit and exploit the advantages of hybrid rice, using the dominant varieties as “paternals” by means of “paterns of excellence - mutations of varieties” and “mothers” of different varieties with corresponding nutritional characteristics, selectively produce new varieties of high-quality, resistant and productive rice, and develop new varieties of rice with higher yields, thereby increasing rice production。
Second, the full use of hybrid rice cultivation technologies. The cultivation of hybrid rice crops is a more complex process, the key to which is the adaptation and improvement of planting techniques, which should include field management, seeding management, harvesting management and hybrid management. These technologies play a key role in increasing crop yields, while also effectively saving costs。
Third is the rational use of fertilizers, timely application and better use of resources. Mixed rice is subject to higher requirements for fertilizer distribution owing to increased resistance and production at the monolithic and variety levels. To that end, proper fertilizer distribution strategies must be adopted to rationalize the use of fertilizers, ensure their full and effective use and effectively increase rice production。
Fourth is the development of a hybrid rice resistance theory system to improve disease resistance. A hybrid rice crop is generally more stable than a single rice crop when it is affected, but different
