In this ordinary March when the grass is growing and the orioles are flying, and the flowers are red and the willows are green, the blooming rape flower fields in Dongcheng Street, Nanchuan District, Chongqing City, welcome a group of unusual tourists.
From March 12th to 13th, the "National On - site Observation and Exchange Meeting on the Multifunctional Development and Utilization of Rape" jointly hosted by the National Agricultural Technology Extension Service Center and the Chongqing Municipal Agriculture and Rural Affairs Commission, and jointly organized by Southwest University, the People's Government of Nanchuan District, and the Chongqing Municipal Agricultural Technology Extension General Station was successfully held in Chongqing City.

Academician Guan Chunyun of the Chinese Academy of Engineering, Academician Wang Hanzhong of the Chinese Academy of Engineering and vice president of the Chinese Academy of Agricultural Sciences, leaders of the National Agricultural Technology Extension Service Center, experts from the Chinese Academy of Agricultural Sciences, as well as experts from the promotion departments of 18 rape - producing provinces and cities across the country, representatives of demonstration counties for the integration of rape fertilizer and pesticide reduction technology models, representatives of relevant scientific research and teaching units and enterprises, leaders in charge of rape production technology in local districts and counties, and media representatives, a total of more than 200 people participated in the meeting. Liu Zufeng, the chairman of Hubei Yishizhuang Agricultural Technology Co., Ltd., and agrochemical staff participated in this meeting as representatives of core enterprises for the green, high - quality, and efficient development of rape across the country.
On the morning of the 12th, the participants observed the rape production demonstration site in Dongcheng Street, Nanchuan District. The site was divided into 10 major areas, mainly displaying a number of contents such as standardized cultivation techniques for high - quality rape and multifunctional development and utilization.

Among them, Yishizhuang's special slow - release fertilizer for rape became a major highlight in the 3,000 - mu demonstration garden. Yishizhuang's special slow - release fertilizer for rape not only formed a series of comparative demonstration areas in the rape fertilizer reduction and efficiency - increasing technology model, including no fertilization, customary fertilization, applying 30 kg of special slow - release fertilizer for rape per mu, applying 40 kg of special slow - release fertilizer for rape per mu, applying 50 kg of special slow - release fertilizer for rape per mu, and applying 60 kg of special slow - release fertilizer for rape per mu.

Moreover, it was integrated into a number of technologies such as simplified high - yield cultivation, full - process mechanized production, reduction of chemical pesticides, research and development of new disease - resistant varieties and new technologies, and multifunctional utilization with the optimal local fertilization amount. With the technical support of the expert team, Yishizhuang's special slow - release fertilizer for rape, which has the three technical characteristics of "comprehensive nutrition, quality improvement and efficiency increase", "long - acting slow - release, synchronous supply and demand", and "one - time application, time - saving and labor - saving", has become an indispensable important link in the rape industry chain.
At the opening ceremony, Ding Zhongping, the secretary of the Nanchuan District Party Committee, and Li Xufeng, the secretary of the Party Committee of Southwest University, delivered speeches respectively. Liu Xin, the deputy director of the National Agricultural Technology Center, made an important speech. Academician Wang Hanzhong, the vice president of the Chinese Academy of Agricultural Sciences, and others gave special reports such as "The Multiple Functions and Development Strategy of Rape" and "The Nutritional Rape Industry and a Healthy China".
On the 13th, at the rape industry development seminar, representatives of some major production provinces, cities, and districts made typical speeches, summarized the current situation and development ideas of rape production, and reported on the integration and demonstration of the "double reduction" technology for rape. Representatives from Hubei, Jiangxi, Anhui, Chongqing, Sichuan and other places all said that Yishizhuang's special slow - release fertilizer for rape had achieved remarkable results in the "345" model of the green, high - yield and efficient technology for rape. The meeting also analyzed the multifunctional development and utilization of rape for oil, vegetables, flowers, fertilizers, and honey in various regions, as well as the main existing problems and solutions.

To thoroughly implement the spirit of this meeting, Yishizhuang Company will continue to take its advantageous fertilizer products as a breakthrough point, integrate upstream and downstream industries such as seeds, pesticides, agricultural machinery, multifunctional development and utilization, and large - scale operators. Relying on the relevant technologies of the expert team and the agricultural technology promotion department, it will cooperate to create new breakthroughs and a new pattern in the grain and oil industry.
