Abstract:

The rice “three controls” fertilization technology is a new type of fertilization technology with the main content of fertilizer control, seedling control, and disease control （referred to as “three controls”）. After the technology was introduced in Jiangxi, the application period of tillering fertilizer and ear-grain fertilizer was often inconsistent with the local traditional fertilization habits during the trial and demonstration process, resulting in poor weeding effect, increased production costs, and difficulty in controlling rice quality. In response to this situation, we have carried out research on key techniques and reinnovated the rice “three controls” cost-saving and efficiency-increasing technologies suitable for application in Jiangxi. Compared with traditional fertilization habits, this technology could increase rice yield by 408.0 kg/hm 2, save costs by 258.0 yuan/hm2, and ultimately save costs and increase efficiency by 1 287.0 yuan/hm2.

Key words: “three controls” fertilization technology, lodging resistance, reduce pests and diseases, cost-saving and efficiency-enhancing

摘要：

水稻“三控”施肥技术是以控肥、控苗、控病虫（简称“三控”）为主要内容的一种新型施肥技术。引进江西后,在试验示范过程中常出现分蘖肥、穗粒肥施用时期与当地传统施肥习惯不一致的情况,造成除草效果不佳、生产成本提高及稻米品质难控制等一些问题。针对此情况,开展了其关键技术的研究攻关,再创新了适合江西推广应用的水稻“三控”节本增效技术。与传统施肥习惯相比,该技术可实现水稻增产408.0 kg/hm2、节省成本258.0元/hm2,最终节本增效1 287.0元/hm2。
