The highest yield per mu is 813.58 kilograms!This demonstration base in Jiangsu Province leads the way in increasing grain production and efficiency with new varieties and new technologies.

At the end of autumn and the beginning of winter, it is the harvest season of late-maturing rice. Over the past few days, golden rice waves have surged in Qingfeng Village, Touqiao Town, Guangling District, Yangzhou City, at the Yangzhou Promotion Demonstration Base of Jiangsu Province’s Modern Agriculture (Rice and Wheat) Industrial Technology System. Agricultural machinery shuttles across the fields, and the air is filled with the smell of harvest. Yangzi Evening News/Ziniu News reporters witnessed the harvesting and yield testing process of various high-quality rice varieties in the province at the base. On November 14, the reporter learned some of the measured yield data from the Jiangsu Lixiahe Agricultural Science Research Institute. The highest Wuyujing crop was 377, with a yield per mu of 813.58 kilograms.

Share the joy of harvest

According to reports, the Jiangsu Modern Agriculture (Rice and Wheat) Industrial Technology System Promotion Demonstration Base has implemented new rice and wheat varieties and high-yield cultivation, precision fertilization, resistance identification, and green prevention and control new technology test demonstrations in the past two years, and selected suitable products along the river and in the countryside. The new rice and wheat varieties and new technologies that can be promoted in the Xiahe area have played a leading role in driving farmers to save costs, increase income and become rich, and to ensure national food security.

A bumper harvest is expected in the experimental fields

Teacher Zhu Jinlei, a technician at the base, told reporters that the core test demonstration base of the Yangzhou Promotion Demonstration Base Project is 503 acres, and the demonstration site construction is 688 acres. This year, the base has mainly completed a comparative test on the screening of new high-quality late-maturing medium-japonica rice varieties, a demonstration of the effect of ear fertilizer application for machine-transplanted rice, a green rice disease prevention and control test, a test on the identification of resistance to rice blast and rice smut, and bio-chemical pesticides Experiments on preventing and controlling rice blast and rice smut, etc. The demonstration variety of rice “machine-transplanted rice special ear fertilizer application effect” is Ningxiangjing No. 9. When applied with special ear fertilizer for rice, compared with conventional compound fertilizer with the same nitrogen content, the base internode is significantly shortened and the lodging resistance is improved, and the actual harvest is achieved. The yield reached 800 kg/mu, an increase of more than 10%. In terms of new high-quality rice varieties, the demonstration rice varieties include Wuyujing 377, Yingxiang No. 1, Yangxiangyu No. 1, Taixiangjing 1402, Wuxiangjing 196, and Nephrite Zhong Among the 16 new varieties including Ke, Wuyujing 377 has an actual yield of 813.58 kg/mu.

Beautiful rice fields

Researcher Liu Yongfeng, director of the base, said that the base uses biological pesticides to prevent major diseases at the ear stage of rice, reducing the amount of chemical pesticides by more than 30%. The control effect on rice blast and rice smut is more than 85%, which is better than chemical agents. After seed dressing treatment with biopesticides, the prevention and control effect of rice bakanae disease reaches 85%. In addition, relying on the rice disease prevention and control innovation team of the Plant Protection Institute of the Jiangsu Academy of Agricultural Sciences, we conduct resistance identification tests on rice blast and rice smut every year, providing valuable advice for subsequent variety approvals. Last year, a total of 450 rice varieties were identified for rice blast resistance, and this year the number of rice materials increased to 1,144. The team continues to use biological control and chemical collaborative prevention and control technologies to prevent and control diseases at the ear stage, improving the level of green prevention and control of major rice diseases.

golden rice waves

The reporter learned that recently, researcher Sun Hongwu, deputy president of the Jiangsu Academy of Agricultural Sciences, researcher Xu Ming, director of the Jiangsu Provincial Seed Nanfan Nanjian Station, researcher Li Aihong, director of the Jiangsu Lixiahe Agricultural Science Institute, and professor Li Yunhe of Henan University, etc. Experts inspected the base construction on site. Sun Hongwu, deputy director of the Jiangsu Academy of Agricultural Sciences, pointed out that the construction of the Yangzhou rice and wheat base has achieved initial results, and it is necessary to continue to strengthen technology introduction and demonstration, create a green, high-yielding and efficient demonstration model of rice and wheat, and provide sustainable technical support for high-quality green production of rice and wheat.Yangzi Evening News/Ziniu News reporter Chen Yong
