通过测土配方施肥3414试验设计及磷肥用量试验研究,进一步探索江苏省响水县不同土壤类型的施肥参数,提出肥料效应函数模型及推荐施肥量,为响水县水稻推广测土配方施肥技术提供依据。为进一步研究江苏省响水县水稻主体推广品种土壤的施肥参数和施肥模型,完善测土配方施肥的应用指标体系,为响水县水稻推广测土配方施肥技术提供依据。2014年5-10月,在响水县的小尖镇、大有镇、陈家港镇进行2个点的3414和1个点的磷肥
Based on the experiment design of soil testing and compound fertilization 3414 and the experimental study on the amount of phosphate fertilizer, the fertilization parameters of different soil types in Xiangshui County of Jiangsu Province were further explored. The fertilizer effect function model and the recommended fertilization rate were put forward to provide the technology of soil testing and formula fertilization for rice in Xiangshui County in accordance with. In order to further study the fertilization parameters and fertilization model of paddy rice in Xiangshui County, Jiangsu Province, the application index system of soil testing and formula fertilization was perfected to provide basis for popularizing the technology of soil testing and formula fertilization by rice in Xiangshui County. From May to October 2014, 3414 and 1 point of 2-point phosphate fertilizer were applied in Xiaoshi town, Dadou town and Chenjiagang town of Xiangshui County
