The Ministry of Agriculture has listed the precise quantitative rice cultivation technology as the main technology for the creation of high-yielding technologies. This year, the demonstration and promotion area in Yunnan Province, which is located in the southwestern frontier, has reached 1.2 million mu, which is 20% higher than the planned area for promotion.

According to the person in charge of the Yunnan Provincial Department of Agriculture, this year's Yunnan Province suffered a catastrophic drought in one hundred years, and the large-scale demonstration and promotion of precise quantitative rice cultivation techniques will help realize the goal of not reducing production in the year of major disasters.

Precise quantitative rice cultivation technology is a rice production technology system that enables the entire process of rice production and the precise regulation of technical indicators. Since 2005, Yunnan Academy of Agricultural Sciences, Agricultural Technology Extension Station and Nanjing Agricultural University have cooperated to introduce precise quantitative cultivation techniques of rice for demonstration and promotion. The initial demonstration area for this technology in Yunnan was only 84 acres. In 2007, it promoted 7,099 acres. In 2008, it quickly increased to more than 70,000 acres, and in 2009 it expanded to 600,000 acres. This year, the agricultural sector originally planned to promote the application of precise quantitative rice cultivation techniques in 1 million mu of paddy fields, but the final promotion area reached 1.2 million mu.

Large-scale realization of cost-saving efficiency is an important reason for the rapid promotion of quantitative rice cultivation technology in Yunnan. According to the researchers, the average yield per mu in the experimental field of rice in Yunnan has increased by more than 10%. At the same time, this technology can increase the nitrogen use efficiency from 30% to 40%, reduce the amount of fertilizer applied, protect the ecological environment, and save 40% of irrigation water per acre through dry and wet irrigation management and thin water irrigation technology. %.

According to Yunnan Agricultural Technology Extension Station, since the introduction of quantitative rice cultivation techniques in Yunnan in 2005, Yunnan Province has held thousands of trainings. Nearly a thousand scientific and technical personnel and tens of thousands of households have been trained to master this technology.

A few days ago, in accordance with the deployment of the national professional and technical personnel knowledge update project, Yunnan Provincial Department of Human Resources and Social Security, the Department of Agriculture, and the Academy of Agricultural Sciences undertook the “National Advanced Training Course on Accurate Quantitative Cultivation Techniques for Rice” and introduced the exchanges to peers from all provinces and regions across the country. Yunnan's experience and achievements in promoting demonstration rice quantitative cultivation techniques.
