摘要: 为探求“山”型配方施肥技术对水稻生长及产量的影响,验证“山”型配方施肥在早稻上的应用效果,开展了早稻“山”型配方施肥应用比较试验,试验设空白对照、习惯施肥、省厅推荐施肥、“山”型配方施肥等6 个处理,对各处理的分蘖情况、农艺性状、产量和经济效益进行了比较分析。结果表明,与习惯施肥、省厅推荐施肥相比,水稻“山”型配方施肥可减少无效分蘖,提高成穗率;增加株高,提高穗长;增加实粒数,提高结实率;增加千粒重。与习惯施肥、省厅推荐施肥相比,“山”型配方施肥稻谷产量增长4.62%~7.4%,纯收入增长850.5~1497.3元/hm2。

Abstract: To explore the influence of“Mountain”type fertilization on rice growth and yield, verify the application effect of“Mountain”type fertilization on rice, the authors carried out comparison test on early rice, including“Mountain”type fertilization, blank control, conventional fertilization, fertilization recommended by provincial authorities and so on, and analyzed the tillering, agronomic traits, yield and economic benefits. The results showed that compared with conventional fertilization and fertilization recommended by provincial authorities,“Mountain”type fertilization decreased ineffective tillers and increased spike rate; increased plant height and ear length; increased real grains and seed rate; increased grain weight. Compared with conventional fertilization and fertilizer recommended by provincial authorities,“Mountain”type fertilization increased rice yield by 4.62%-7.4%, and net income by 850.5-1497.3 yuan/hm2.
