Yangda Rice cultivation technology reaches international advanced level

It was learned from Yangda Agricultural College that the “Research and Application of Cultivation Techniques for High Yield and Water Nutrient Utilization of Rice” recently passed the appraisal organized by the Department of Education of Jiangsu Province. It is understood that this achievement has not only won a number of national patents, but also has reached the international advanced level.

According to Professor Yang Jianchang, the person in charge of the project, since 1997, despite the increasing input of fertilizers, rice production in China has been faltering. How to further tap the rice production potential, achieve simultaneous increase in production and the efficiency of water and fertilizer resources, has become a major issue for rice production in China. In order to significantly increase food production, in recent years, crop super high yield research and demonstrations have been carried out throughout the country, and some super high yield records have been obtained. However, these records are only obtained in small areas or in specific years or in climate and geography, and are mostly high. The price of fertilizer, water, labor, etc. Based on this, the research group has, since 2000, established a cultivation technology system for high-yielding and high-efficiency utilization of rice nutrients through a decade of efforts.

Since 2006, the project has been demonstrated and applied in Jiangsu Province. Since 2007, it has been expanded to demonstration and promotion in Shanghai and Anhui Provinces. According to statistics, from 2006 to 2009, the cumulative effective demonstration area was 2.05 million hectares. Compared with the local high-yielding cultivation, the output after applying this technology increased by 7.0%, the nitrogen fertilizer utilization efficiency increased by 17.1%, and the irrigation water utilization efficiency increased by 39.7. %, the accumulative income increase was 2.325 billion yuan. It is estimated that by 2012, the area of ​​promotion in provinces (cities) such as Jiangsu, Zhejiang, Fujian, Chongqing, and Shanghai will reach 6 million hectares.
