控释肥对水稻生长和土壤养分含量的影响
Effects of Controlled-Release Fertilizer on Soil Nutrient Content and Growth of Rice
,
摘要:

为了解控释肥对土壤理化性状及水稻产量的影响,开展了田间小区试验。试验设置4个处理,以普通肥料处理为对照,测定了土壤理化性状及水稻产量。结果表明:在水稻生长中后期,施用控释肥处理的土壤碱解氮、有效磷、速效钾含量以及叶片中叶绿素相对含量(SPAD值)均高于对照处理的;控释肥处理的水稻增产效果明显,在施用的总养分与对照处理等量或减少23.3%的情况下,增产率为30.8%~37.1%。施用控释肥对水稻生产有促进作用,其施用量可根据当地实际情况,与对照处理等养分总量或养分总量减少23.3%~35.0%施用。

Abstract:

In order to understand the effects of controlled-release fertilizer on soil physical and chemical properties and rice yield, a field plot experiment is carried out. Four treatments are set up in the experiment. The soil physical and chemical properties and rice yield are measured with common fertilizer treatment as the control. The results show that in the middle and late stages of rice growth, the content of soil alkali-hydrolyzed nitrogen, available phosphorus, available potassium and the relative chlorophyll content (SPAD value) of the leaves in the controlled-release fertilizer treatment are higher than those in the control treatment. The controlled-release fertilizer treatment has a significant increase in rice yield. When the total nutrient applied is equal to or 23.3% less than that of the control treatment, the yield increase rate is 30.8% to 37.1%. The application of controlled-release fertilizer has a promoting effect on rice production, and the application amount can be the same as the total amount of nutrients in the control treatment, or 23.3%-35.0% less than the total amount of nutrients applied according to the actual local conditions.
