为科学评价不同控释肥料在江苏仪征市小麦上的应用效果,探求最适宜的肥料使用方法及肥料运筹,2014~2015年在小麦上开展了控释肥试验。试验得出,与常规区相比控释肥区氮肥施用平均节省2.07kg/亩,节约16.1%,三点总体平均后控释区比常规区增加17.68kg/亩,亩增加4.27%,控释肥在生产中比常规施肥有一定的增产效果。控释肥在产量构成因子穗数表现为促进基本苗分蘖数的发生,促进粒数增加,在效益上去除肥料及人工每亩10元成本,控释区省工节本增收13.6元。通过试验可见,控释肥具有省工、增产、增效、环保等多方面的作用。
In order to evaluate the application effects of different controlled release fertilizers on wheat in Yizheng City of Jiangsu Province, the optimal application of fertilizers and fertilizers were explored. From 2014 to 2015, a controlled release fertilizer experiment was conducted on wheat. The results showed that compared with the conventional area, the average nitrogen release rate of controlled release fertilizer area was 2.07kg / mu, saving 16.1%, the average post-control release area of three points increased by 17.68kg / mu compared with the conventional area, the increase of mu was 4.27% Fertilizer in the production than conventional fertilization have a certain effect. Controlled-release fertilizer in the yield factor spike number showed to promote the occurrence of basic seedling tillering number, and to promote the increase of the number of grain, the fertilizer and artificial removal of 10 yuan per mu cost, the controlled release section of the provincial income of 13.6 yuan. Can be seen through the test, controlled release fertilizer with labor, increase production, efficiency, environmental protection and many other roles.
