On April 19th, the Yunnan Crop Association invited relevant experts to conduct on - site yield - measurement and acceptance of the hundred - mu demonstration plot of the "Maturity and Application of High - Efficiency Slow - Release Special Fertilizer for Rape" project hosted by Hubei Yishizhuang Agricultural Technology Co., Ltd. More than 30 experts from both inside and outside the province, including Researcher Hu Qiong from the Oil Crops Research Institute of the Chinese Academy of Agricultural Sciences, Researcher Zhang Min from the Nanjing Institute of Agricultural Mechanization of the Ministry of Agriculture and Rural Affairs, Researcher Hou Shumin from the Crop Research Institute of the Anhui Academy of Agricultural Sciences, and Researcher Li Genze, the director of the Cash Crops Research Institute of the Yunnan Academy of Agricultural Sciences, participated. The regional manager representative of Hubei Yishizhuang Agricultural Technology Co., Ltd. in Yunnan Province attended the meeting and assisted the experts in yield - measurement.
On - site, the expert group first observed the new variety display area and related experimental areas, and then successively went deep into the demonstration area of the "Maturity and Application of High - Efficiency Slow - Release Special Fertilizer for Rape" project in Xingduolu Village, Luoxiong Sub - district, Luoping County to conduct on - site yield - measurement and acceptance of the special slow - release fertilizer for rape. The application area of this demonstration area is 107 mu. It adopts new high - heterosis hybrid rape varieties, unified full - process mechanization, and integrates key technologies such as reducing the use of chemical fertilizers and pesticides, returning all previous - crop straw to the field, and green prevention and control. The crops grow vigorously and evenly, with plump pods, achieving the goals of light - simplified cultivation, increasing production and income, and presenting a relatively complete model field for large - scale rape cultivation to local growers.

On April 20th, based on the observation and yield - measurement inspection, the expert group held the "On - site Observation and Seminar on the Full - Process Mechanized Production of Reducing the Use of Chemical Fertilizers and Pesticides in Rape". Relevant leaders and experts delivered important speeches. Sun Miao, the regional manager of Hubei Yishizhuang in Yunnan, on behalf of the company, gave a detailed introduction to the development of the "Maturity and Application of High - Efficiency Slow - Release Special Fertilizer for Rape" project at the meeting. He said that judging from the growth situation throughout the growth period and the results of yield - measurement and acceptance, the special slow - release fertilizer for rape has achieved the desired effect. Next, the company will continue to cooperate with Yunnan rape experts to improve the dosage and fertilization procedures of the special fertilizer, striving to achieve precision and accuracy, and promoting the "green and efficient" development of the rape industry in Yunnan.
