摘要
[目的]探求丹粳17号合理的密度和施肥量。[方法]设计4种插秧密度3种施肥量,采用随机区组设计进行田间试验,对不同密度、不同施肥量对产量及其性状的效应进行分析。[结果]密度对产量、穴成穗数和穗粒数具有显著影响,随着密度的增加穴成穗数增加,穗粒数减少,但产量不一定增加,产量受穗数和穗粒数的共同作用。施肥量则主要影响结实率,从而影响产量。随着施肥量的增加,结实率降低,产量降低。密度和施肥在产量、成穗率、株高、结实率和穴成穗数上表现出较明显的互作效应。[结论]实际生产中可以针对特定的密度采用相适应的施肥量。
[ Objective] The aim was to find out suitable transplanting density and fertilization for Danjing 17. [ Method] The effects of transplanting density and fertilization on yield and other agronomic traits were comparatively analyzed by taking randomized block design among disposals of 4 transplanting densities and 3 kinds of fertilization. [ Result] The results showed that ： significant effects of transplanting density were found on yield, panicles per hole and grains per panicle. With increase of transplanting density, panicles per hole increased, grains per panicle decreased, but yield changed uncertainly, for which was influenced by panicles per hole as well as grains per panicle. The significant effects of fertilization were mainly on seed-setting rate and yield. With increase of fertilization, seed-setting rate and yield both increased. Interaction effects between transplanting density and fertilization were showed obviously on yield, spike rate, plant height, seed-setting rate and panicles per hole. [ Conclusion] Transplanting density should be matched to fertilization.
