| 摘 要： | 研究了水稻缓释肥对崇明县直播水稻成穗率、产量及产量构成的影响。结果表明:施用水稻缓释肥后,直播水稻成穗率较常规施肥处理有明显增加;在等氮条件下,产量显著高于目前大面积采用的常规施肥处理;减氮30%,水稻产量与常规施肥处理相仿。

| Abstract: | Field-plot experiments with direct-seed rice were carried out in Chongming County to study the effects of slow-release fertilizer on the percentage of ear-bearing tiller,yield and yield components of rice.The results showed that compared with the conventional fertilizer treatment,application of slow-release fertilizer obviously increased the percentage of ear-bearing tiller of direct-seed rice,significantly improved the rice yield under the same amount of N fertilizer applied,and reached nearly the same rice yield even when the N fertilizer rate was reduced by 30%. |
