Yield Measurement and Acceptance of the Rape Maturity Project: Prominent Achievements in Wuxue and Jingmen

After going through the severe cold, the smiles are as golden as the fields. Now that the flourishing season has passed, it's time for a bountiful harvest. I seem to be able to smell the fragrance of rapeseeds. From May 7th to 8th, 2022, the Hubei Rape Office organized relevant experts to conduct on - site inspection and yield measurement of the three demonstration areas in Dafasi Town, Wuxue City, Yuchuan Town, Wuxue City, and Shayang County, Jingmen City for the project "Rape High - Efficiency Slow - Release Special Fertilizer Maturity and Application" under the National Key Research and Development Program. Leaders and experts from the Hubei Rape Office, Huazhong Agricultural University, the Oil Crops Research Institute of the Chinese Academy of Agricultural Sciences, and local agricultural departments came to guide. Liu Zufeng, the chairman of Hubei Yishizhuang Agricultural Technology Co., Ltd., and technical personnel assisted the experts in yield measurement on - site.

The application area of the demonstration point in Dafasi Town, Wuxue City is 400 mu, the application area of the demonstration point in Yuchuan Town, Wuxue City is 3,000 mu, and the application area of the demonstration point in Shayang County, Jingmen City is 7,000 mu. All of them apply 40 - 50 kg/mu of the "special slow - release fertilizer for rape" (with N - P2O5 - K2O content of 25 - 7 - 8 and medium and trace elements such as calcium, magnesium, boron, and zinc) developed by Huazhong Agricultural University and produced by Hubei Yishizhuang Agricultural Technology Co., Ltd. in one - time. Moreover, the demonstration fields also integrate high - quality varieties, no - tillage and aerial seeding with straw returning to the field and other light - simplified and efficient production modes, adopt unified management of key technologies for green and efficient rape planting, and conduct full - process mechanized production.

Representative demonstration fields were selected in the demonstration areas for yield measurement. The average density was measured on - site, and indicators such as the average number of effective siliques per plant and the number of grains per silique were measured to standardize the measurement results. According to the yield measurement results, the demonstration areas in Dafasi Town, Wuxue City, Yuchuan Town, Wuxue City, and Shayang County, Jingmen City have achieved the goals of light - simplified cultivation, increasing production and income, and reducing fertilizer application and increasing efficiency. The expert group unanimously believed that the implementation of the project "Rape High - Efficiency Slow - Release Special Fertilizer Maturity and Application" under the National Key Research and Development Program has effectively promoted the reduction of industrial fertilizer application and increase of efficiency in local rape production, and suggested strengthening the promotion efforts.

It is understood that the experimental demonstration points of the project "Rape High - Efficiency Slow - Release Special Fertilizer Maturity and Application" under the National Key Research and Development Program from 2021 to 2022 are spread all over the main winter rape production areas in provinces such as Hubei, Hunan, Jiangxi, Sichuan, Chongqing, and Yunnan. Currently, the yield measurement and acceptance work in various places is being carried out intensively and orderly. Follow - up reports on the yield measurement results will also be carried out in real - time. Please stay tuned!
