Precise and Quantitative Cultivation for High Yield in Rice

It is the developmental orientation of rice culturing science and technology and the creative development of rice cultivation to explore advanced and suitable precise and quantitative rice cultivation which also meets the five comprehensive requirements, i.e. high yield, fine quality, high efficiency, ecology and security. The authors stated clearly rice leaf age model, rice high-yielding population quality index, general approach to form high-yielding and good quality rice population and quantitative standards for diagnose by stage. The precise quantification of rice cultivation techniques was made in terms of sowing date, sturdy seedling nurturing, rational transplanting seedling number, hill space in row and between-row space, fertilization and water management. Practice proves that rice precise and quantitative cultivation theory and technique system have a wide directing effect and applicable value.
