Abstract:

The effects of Penshibao and Shiermei on economic traits and yield of rice were studied in this paper, using early rice variety of Zhongjiazao 17 and late rice Yongyou 538 as materials. The results showed that spraying foliar fertilizer had a significant effects on yield of early rice and late rice, compared to the control, the yield of early rice was increased by 7.92%~25.90%, and the yield of late rice was increased by 5.31%~12.06%. Spraying Shiermei at heading stage has better effect on yield, and the optimum dosage was 25 g/667 m2.

Key words: rice, foliar fertilizer, heading stage, yield

摘要：

以早稻中嘉早17和连作晚稻甬优538为材料，研究了施用叶面肥“喷施宝”和“施尔美”对早、晚稻经济性状和产量的影响。结果表明，早、晚稻在穗期喷施叶面肥均有明显的增产效果，早稻喷施叶面肥较未喷施对照增产7.92%~25.90%，晚稻喷施叶面肥较未喷施对照增产5.31%~12.06%；2种叶面肥以喷施“施尔美”的增产效果更好，用量宜控制在25 g/667 m2。
