The precise quantitative cultivation of rice is based on the rice leaf age model and population quality theory and technology. According to the leaf age process, the rice growth process and organ construction diagnosis are quantified, and the population quality and its dynamic index are quantified according to the high yield formation law. According to the principle and method of quantitative measures of regulation measures, the whole process of cultivation technical indicators is quantified, and then these three parts are systematically integrated to create a rice digital production technology system that can make the whole process of rice growth and various control technical indicators accurate. Including precision sowing and cultivating strong seedlings, precise control of basic seedlings, precise operation of fertilizers, precise quantitative irrigation, precise control of pests and diseases, using this technology, rice yields 10% more than conventional transplanted rice, 10% fertilizer saving, water saving 15 %, the pesticide dosage is reduced by 20%, and the mu yield is increased by 100 yuan, which is suitable for popularization and application in the main rice producing areas.
1, precise sowing and breeding
When planting rice, choose the right time to sow, through the fertility bed dry breeding, plastic tray moist breeding, double-membrane breeding and other breeding methods, to cultivate standardized leaf stalks that adapt to different planting methods.
2. Precise control of basic seedlings
According to the quality of seedlings, the occurrence of tillers and the characteristics of ear formation, the basic seedling formula was accurately calculated according to the basic seedling formula, so that the plant spacing of the seedlings was rationally configured.
3. Accurate operation of fertilizer
According to the basic soil fertility, target yield, and fertilizer utilization rate, the Stanford difference method is used to accurately calculate the total nitrogen requirement. At the same time, according to the mass of the population, the stem and fertilizer can be rationally managed, and the application of NPK can be balanced.
4, accurate quantitative irrigation
According to the characteristics of water absorption and utilization and soil water potential in different growth stages of rice, the dry and wet alternate irrigation mode was adopted in the whole growth period.
5, precise prevention and control of pests and diseases
Through the selection of disease-resistant varieties, suitable sowing, agronomic measures such as the regulation of fertilizers in the field, and chemical control measures, we can accurately control pests and diseases.
