Rice plant transplanting side deep fertilization technology has great action in Jilin

In order to thoroughly implement the concept of green development of agriculture proposed by the central government and promote the goal of zero growth of pesticides and fertilizers, on May 18, Jilin Province Agricultural Mechanization Management Center organized a demonstration demonstration of deep-fertilization technology in rice transplanting in Meihekou City. In the Shengfeng Agricultural Mechanization Production Cooperative of Yongsheng Village, Shancheng Town, Meihekou City, the “Jilin Province Paddy Field Fertilizer High-efficiency Mechanization Experimental Demonstration Demonstration Field, Agricultural and Rural Ministry Rice Field Transplanting Synchronous Side Deep Fertilization Technology Experimental Demonstration Field” was established to lead and The demonstration promoted the popularization and rapid development of rice production and fertilizer technology in the province.

Since the history of rice fertilization, traditional artificial fertilization methods have been adopted, especially in the northeast of high-quality rice producing areas. The amount of chemical fertilizer is large, and the base fertilizer is generally artificially sprinkled on the surface, and then turned (spin) In the soil, the water is filled with the shovel and then transplanted, and the mash is a "traditional" method of artificially raising the water directly. This type of fertilization has followed thousands of years. Not only is the fertilizer utilization rate low, the fertilizer is wasted, the labor is high, the cost is high, and the water source pollution is serious, which has become a bottleneck restricting the improvement of rice quality and quality and safety.

Synchronous side deep fertilization mechanization technology of rice transplanting rice is a new technology and new method to effectively reduce the amount of chemical fertilizer used and improve the utilization rate of chemical fertilizers under the premise of ensuring rice yield. This technology combines the basic fertilizer and manure used in the traditional rice planting twice, and combines them into one. The rice transplanter with the side deep fertilization device is used to transplant the rice at the same time. The fertilizer is quantitatively, positioned, and evenly applied to the mud at the side of the seedlings 3 to 5 cm and 5 cm deep, and covered with mud. This method of fertilization can significantly improve the utilization rate of chemical fertilizers, reduce the amount of chemical fertilizers and non-point source pollution, and continuously control the release of nutrients through slow release fertilizer for 60 days, ensuring the nutrient supply of rice in each stage before the application of panicle fertilizer. Effectively reduce the cost of base and manure fertilization and the amount of fertilizer, and improve the quality and quality of rice. Jiufu, Yanmar, Ameike, Chunmiao 4 kinds of original original self-contained side-deep fertilization transplanter and 6 sets of Hunan Longzhou side deep fertilization device installed on Yanmar and Kubota transplanting machine were carried out. Live job demonstration.
