摘要
为探究新型植物生长调节剂能百旺2.0在水稻上的应用效果,以Y两优911为材料,以喷施清水为对照,分析能百旺2.0在不同施氮量条件下对水稻产量、品质、干物质积累和肥料利用率的影响。结果表明:喷施能百旺2.0显著提高了水稻千粒质量,显著降低了水稻茎鞘、叶的干物质质量,提高了籽粒干物质质量,显著提高了氮肥偏生产力、氮肥农学利用率、氮肥回收利用率和氮肥生理利用率。综合分析,叶面喷施能百旺2.0可促进水稻干物质向籽粒部位积累,有利于产量和品质的提高,同时可提高肥料利用率。
In order to explore the application effect of new plant growth regulator Nengbaiwang 2.0 on rice,Y Liangyou 911 was used as material and spraying clear water as control.The effects of Nengbaiwang 2.0 on rice yield,quality,dry matter accumulation and fertilizer use efficiency under different nitrogen application rates were analyzed.The results showed that spraying Nengbaiwang 2.0 significantly increased the 1000-grain weight of rice,significantly decreased the dry matter mass of rice stem,sheath and leaf,and increased the grain dry matter mass.Nitrogen partial productivity,nitrogen agronomic use efficiency,nitrogen recovery efficiency and physiological use efficiency of nitrogen fertilizer were significantly improved.Comprehensive analysis showed that foliar spraying Nengbaiwang 2.0 could promote the accumulation of dry matter to the grain,improve the yield and quality,and improve the fertilizer use efficiency at the same time.
