摘要
为探寻湖南慈利县水稻适宜的施肥模式,以水稻品种隆两优华占为试验材料,设置了常规施肥、减氮10%增钾5%、减氮10%增钾10%、减氮10%增钾15%、减氮15%增钾5%、减氮15%增钾10%、减氮15%增钾15%等7个处理,比较了不同处理的水稻产量、品质及种植经济效益.结果表明:减氮增钾对水稻产量和品质影响显著,其中减氮10%增钾10%处理、减氮10%增加15%处理的水稻产量、品质及种植经济效益最高.
Abstract
In order to explore the suitable fertilization mode of rice in Cili County,the rice variety Longliangyouhuazan was used as the experimental material.Seven treatments,including conventional fertilization,10%reduction in nitrogen and 5%increase in potas-sium,10%reduction in nitrogen and 10%increase in potassium,10%reduction in nitrogen and 15%increase in potassium,15%re-duction in nitrogen and 15%increase in potassium,15%reduction in nitrogen and 15%increase in potassium,were set up.The yield,quality and planting economic benefit of rice under different treatments were compared.The results showed that reducing nitrogen and increasing potassium had significant effects on rice yield and quality,among which the rice yield,quality and planting economic benefits were the highest under the treatment of reducing nitrogen and increasing potassium by 10%and reducing nitrogen by 10%and increasing nitrogen by 15%.
