Expert Yield Measurement of Yishizhuang: Labor - Saving and High - Yield Rapeseed

From May 12th to May 13th, 2018, Wang Jijun, the director of the Oil Crops Department of the National Agricultural Technology Extension Service Center, Zhang Wenli, the deputy director of the Agricultural Research Center of the Ministry of Agriculture, Cai Junsong, the director of the Rapeseed Office of Hubei Province, Lu Mingxing, the deputy director, Yang Chaoxin, the deputy director of the Science, Education and Technology Department of the province, Zhang Xuekun, the deputy director of the Oil Crops Research Institute of the Chinese Academy of Agricultural Sciences, and Lu Jianwei, a professor from Huazhong Agricultural University and a member of the National Rapeseed Industry Technology System, and other came to Jiangling County and Shishou City in Jingzhou City, Hubei Province, to conduct on - site yield measurement and acceptance of the core demonstration area of the "345" model for green, high - yield and high - efficiency rapeseed technology. Liu Zufeng, the chairman of Hubei Yishizhuang Agricultural Technology Co., Ltd., and the agrochemical staff, as the R & D and production enterprise of special fertilizers for rapeseed in the demonstration area, participated in this yield measurement and acceptance activity.

On the afternoon of May 12th, the expert group came to Wanxin Village, Majiazhai Township, Jiangling County, Jingzhou City. The rapeseed planting area in this core demonstration area reached 106 mu, with the variety Huayouza No. 9. Direct seeding was adopted, and 45 kg of 40% Yishizhuang special slow - release fertilizer for rapeseed was applied per mu, with unified field management. After on - site yield measurement by the expert group, the average actual yield of rapeseed in this demonstration area was 284.85 kg (wet weight) per mu. The measured water content was 25.7% and the impurity content was 4%. Calculated according to the standard water and impurity of 11%, the actual yield per mu was 225.0 kg. Calculated based on the current market price of 5 yuan/kg, after deducting the cost of 310 yuan, the average net profit per mu could reach about 800 yuan.

The editor found in the field that a rapeseed field next to the demonstration area had serious lodging, forming a strong contrast with the demonstration field. Through communication with Boss Zhang, the demonstration household, it was learned that this field adopted their customary fertilization plan in previous years, showing that the plants generally lodged, and the siliques were overly green and late - maturing, bringing great inconvenience to the later harvesting and having a certain impact on the yield.

On the morning of May 13th, the expert group came to Nankou Town, Shishou City, Jingzhou City, to conduct on - site yield measurement of the core demonstration area of the "345" model for green, high - yield and high - efficiency rapeseed technology. The rapeseed planting area in this demonstration area was 500 mu, with the variety Huayouza No. 13. Direct seeding was uniformly carried out, and 30 kg of 40% Yishizhuang special slow - release fertilizer for rapeseed was applied per mu, with unified field management. After on - site yield measurement, the average actual yield of rapeseed in this demonstration area was 307.43 kg (wet weight) per mu. The measured water and impurity content was 33.7%. Calculated according to the standard water and impurity of 11%, the actual yield per mu was 229.02 kg. Calculated based on the current market price of 5 yuan/kg, after deducting the cost of 282 yuan, the average net profit per mu could reach about 860 yuan.

The "345" model for green, high - yield and high - efficiency rapeseed technology is based on high yield, with the goals of greenness and high efficiency. According to the requirements of the integration of agricultural machinery and agronomy, it adopts the high - yield cultivation technical route of direct seeding and close planting, and integrates and applies the green, high - yield and high - efficiency production methods of new seeds, fertilizers and pesticides. According to the on - site yield measurement data of the two core demonstration areas in Jingzhou City, Hubei Province, the increase in rapeseed yield and efficiency is obvious. It can be seen that Yishizhuang's special slow - controlled - release fertilizer for rapeseed has achieved the goals of balanced nutrition and precise fertilization in rapeseed growth.
