控释肥对水稻产量和效益的影响

Effects of Controlled Release Fertilizer on the Yield and Benefit of Rice

为探究控释肥对水稻产量和效益的影响,以桐梓县为试验地点,探讨了施用控释肥和常规施肥对水稻生长状况、产量和经济效益的影响。研究结果表明,不同施肥方式对水稻的生长和产量具有显著影响。在生长指标方面,不同施肥处理组在株高、穗长和分蘖数上均呈现提高趋势,其中C组效果最佳,提高幅度分别为6.39%,4.61%和5.91%,表明控释肥有利于促进水稻生长发育,增加分蘖和穗长,提高产量;在产量和经济指标方面,C组在各项指标上均表现最佳,相较对照组提高了9.55%,15.24%,35.92%,22.04%和22.92%。

In order to explore the effects of controlled release fertilizer on rice yield and benefit,Tongzi County was taken as the test site to study the effects of controlled release fertilizer and conventional fertilizer application on rice growth,yield and economic bene-fit.The results showed that different fertilization methods had significant effects on the growth and yield of rice.In terms of growth indexes,plant height,panicle length and tillering number of different fertilization treatment groups showed an increasing trend,among which group C had the best effect,with increases of 6.39%,4.61%and 5.91%,respectively,indicating that controlled release fertilizer was beneficial to promote rice growth and development,increase tillering and panicle length,and increase yield.In terms of yield and economic indicators,group C had the best performance in each index,which increased by 9.55%,15.24%,35.92%,22.04%and 22.92%compared with the control group.
