摘要
选取广东普宁地区主要水稻品种——合美占作为试验对象,研究有机肥替代化肥减量对水稻农艺性状、产量、叶片SPAD以及经济效益的影响.试验结果表明,H1、H2有机肥替代处理分别较H0增产3.8%、8.3%,随着有机肥替代量的增加,水稻叶片SPAD值以及经济效益逐渐增加,并在20%有机肥组时达到最高峰,之后呈现下降趋势.表明有机肥可以替代部分化肥,提高水稻产量和品质,实现化肥减量增效的目的.
Abstract
Hemeizhan,the main rice variety in Puning area of Guangdong Province,was selected as an experimental object to study the effects of organic fertilizer replacement on rice agronomic traits,yield,leaf SPAD and economic benefits.The experimental re-sults showed that H1 and H2 were 3.8%and 8.3%higher than H0,respectively.With the increase of organic fertilizer replacement amount,SPAD value and economic benefit of rice leaves gradually increased,and reached the highest peak in 20%organic fertilizer group,and then showed a downward trend.The results showed that organic fertilizer could replace part of chemical fertilizer,im-prove rice yield and quality,and achieve the purpose of reducing fertilizer amount and increasing efficiency.
