Helping Xinyang Rape Reduce Fertilizer Use by 25%: Whats Your Edge?

On April 12th, the "Field Observation Meeting on Technologies for Reducing the Application of Chemical Fertilizers and Pesticides in Winter Rape in Henan Region" co - hosted by Xinyang Agricultural College and the Institute of Industrial Crops of Henan Academy of Agricultural Sciences, and co - organized by the Guangshan County Agricultural Bureau and Hubei Yishizhuang Agricultural Technology Co., Ltd. was successfully held in Guangshan County, Henan Province. The meeting invited more than 80 people, including relevant experts of the "Two Reductions in Rape" project of the National Key Research and Development Program, post scientists and backbones of the rape industry technology system, rape breeding experts, agricultural technology extension personnel, and heads of new agricultural business entities.

At the beginning of the meeting, local leaders and representatives of project experts delivered important speeches, briefly summarizing the significance of the "Two Reductions in Rape" project and its impact on local agricultural development. Teacher Xiao Rongying from Xinyang Agricultural College, one of the local project technical leaders, gave a detailed introduction to the current progress.

She emphasized that rape cultivation in Xinyang mainly adopts the rotation of paddy fields and dry land, and there is great room for the development of the planting area. However, problems such as unstable rape prices, large application of chemical fertilizers and pesticides, low nutrient utilization rate, and backward planting technologies in production have greatly reduced farmers' enthusiasm for planting. In response to the above problems, the project technical leaders carried out key technology research and verification through experiments such as the gradient test of the application amount of special slow - release fertilizers for rape (30 kg, 40 kg, 50 kg, and 60 kg per mu), the coordinated and synergistic regulation test of medium and trace elements, the test of straw returning to the field for suppressing weeds with dense planting, the green prevention and control test of diseases, insects and weeds, and the test of screening high - efficiency rape nutrient varieties. The mature key technologies suitable for the rotation system of paddy fields and dry land of winter rape in the Henan region were integrated to form a set of rational comprehensive technical models for reducing the application of chemical fertilizers and pesticides and their efficient utilization.

With the strong support of the local government and entrepreneurs, the multifunctional development and utilization of rape were carried out. On the basis of oil use, functions such as flower use, vegetable use, and honey use were further developed, driving the development of rural tourism and promoting industrial poverty alleviation in Guangshan County.

After the field observation, the "Training Meeting on Technologies for Reducing the Application of Chemical Fertilizers and Pesticides in Rape" was held in the conference room. At the meeting, relevant authoritative experts trained on the whole - process cultivation management and green prevention and control technologies of rape. Liao Tingting, an agrochemical technician from Hubei Yishizhuang, shared the company's work on "Research and Development and Application of Special Slow - Release Fertilizers for Rape" on behalf of the company. She mainly gave a detailed interpretation from aspects such as research and development ideas, product characteristics, and application situations in various places. Combining with the functional characteristics, she recommended the fertilizer application amount and the best fertilization position under different conditions. The reasonable ratio of nitrogen, phosphorus and potassium in Yishizhuang's special slow - release fertilizer for rape, the supplementation of essential medium and trace elements, the reasonable addition of organic matter, the application of slow - release and controlled - release technologies, and the characteristics suitable for mechanized application attracted the attention of the large - scale growers present. The field - measured effect of achieving yield increase and efficiency improvement while reducing fertilizer use by 25% was unanimously recognized by the participating experts.

The successful convening of this meeting implemented the purpose of the integration of technologies for reducing the application of chemical fertilizers and pesticides in winter rape. It is a small step in promoting the improvement of the quality and efficiency of rape production, and a big step for the company on the path of scientific and technological innovation. Hubei Yishizhuang Agricultural Technology Co., Ltd. will continue to cooperate with other key technologies to strive for the high - yield, high - efficiency, green and sustainable development of rape.
