Accurate quantitative rice cultivation technology is a team led by Prof. Ling Qihong, a famous rice cultivation expert in China. Based on rice leaf age model and rice population quality cultivation and other theoretical and technological achievements, it is adapted to the new cultivation technology system proposed by modern rice cultivation trends. In recent years, it has been demonstrated and promoted in Jiangsu, Jiangxi, Hubei, Anhui, Yunnan, Guizhou, Liaoning, Heilongjiang and other provinces, and has achieved relatively good results. Recently, the Crop Management Department of the Ministry of Agriculture and the National Agricultural Technology Extension Service Center jointly held the National Rice Precise Quantitative Cultivation Technology Promotion Ceremony in Guiyang City, Guizhou Province.
At the launching ceremony, Xie Jianhua, deputy director of the National Agricultural Technology Extension Service Center, asked the provinces responsible for the creation of high yielding rice to establish precise rice cultivation techniques as the main push technology for high yielding rice, select some high-yielding demonstration counties, establish demonstration bases, and strengthen technology. Promotion. It is reported that the Ministry of Agriculture will set up a steering group of precision quantitative cultivation techniques for rice led by Prof. Ling Qihong as the consultant and Professor Zhang Hongcheng of the Yangzhou University. Technical implementation teams will also be set up around the country to formulate technical plans and do a good job of technical training and demonstration.
At the launching ceremony, Professor Ling Qihong made a special report on the technology. According to Professor Ling, from 2005 onwards, in different modes of cultivation such as japonica rice, single and double rice, and hand-planting and transplanting machines in Yunnan, Guizhou, Henan, Jiangxi, Guangxi, Sichuan, Anhui, Liaoning and Heilongjiang In the same variety and fertilization level, the yield is more than 10% higher than the current local cultivation methods, and it has played a comprehensive role in the provincial, provincial, provincial, and provincial laborers.
According to reports, high yield, high quality, high efficiency, ecology, and safety have become the basic goals for the development of rice production in China. The realization of this goal depends to a large extent on accurate quantitative cultivation of rice.
The first is that the high yield of rice requires precise quantitative cultivation. Although there are a variety of cultivation methods for low-yield, high-yield, high-yield, and high-yield rice, the precise quantitative cultivation techniques for rice must be applied to improve resource utilization and economic efficiency. According to the precise nitrogen application test conducted by Jiangsu, the nitrogen application level is about 20 kilograms per acre. With conventional experience of fertilization, the per mu yield is only 500-600 kilograms, while the use of accurate quantitative cultivation can increase the yield per kilogram to about 700 kilograms; if the target is determined With a yield of 600 kilograms per mu and accurate quantitative cultivation, the amount of nitrogen applied per mu can be reduced to about 16 kg.
The second is that high-quality rice production requires precise quantitative cultivation. Regardless of rice quality, whether it is the ratio of polished rice, chalkiness, or gel consistency, protein content, and various evaluation values ​​of cooking and eating are significantly affected by the cultivation techniques. For cultivation measures that have an important influence on the quality of rice, such as sowing dates and fertilizer and water transport operations, only quantification and formulation of technical standards based on the rules and requirements for the formation of good quality, and then the organization of production according to standardized technical regulations can produce high-quality rice that meets standards.
Third, efficient rice production requires precise quantitative cultivation. Precise quantitative rice cultivation techniques can determine the appropriate sowing date, seeding rate, fertilizer application time and amount, water irrigation time and amount, and spraying time of pesticides according to the basic nutrient status of the soil, the local temperature and light resources, and the reproductive characteristics of the varieties. Amount, etc., to achieve precise sowing, precision fertilization, precision irrigation, precise drug requirements. Due to the multiple precise quantification of environmental indicators for the growth of rice, dynamic indicators of population growth and development, and complementary cultivation techniques, people only need to perform quantitative physical and chemical inputs during necessary work hours, not only for cost-saving but also for labor saving, which is conducive to efficient production. The goal.
Fourth, the safe production of rice requires precise quantitative cultivation. The concept of safe rice production includes the self-safety of rice production, and the control of toxic and harmful substances in rice that are produced within the scope allowed by pollution-free, green or organic foods to ensure human health and safety. For example, accurate quantification of rice sowing time and seeding rate can not only avoid the shortage of early seedlings due to low temperature chilling, but also ensure the safe maturation of late rice growth. Accurate use of various fertilizers, pesticides, herbicides, and other chemical reagents in rice production can not only avoid the occurrence of rice fertilizer damage and phytotoxicity, but also can strictly control the content of toxic and harmful substances in rice within the safety standards. To achieve the clean production of rice.
Fifth, ecological agriculture needs precise quantitative cultivation. In recent years, the unreasonable increase in the level and intensity of chemical inputs in rice production in some areas has given rice fields a threat of pollution. Accurate and quantitative cultivation is targeted, straws are returned in full, fertilizer application time and dosage can be accurately quantified, soil nutrients can be well balanced, rice production and environment friendly, and natural coordination.
