摘　　要：针对将乐县水稻生产过程中因缺镁引起稻株叶片黄化、减产等问题,开展不同镁肥施用量试验,探索镁肥对水稻中浙优8号农艺性状及产量的影响。结果表明:施用硫酸镁肥能明显减少中浙优8号因缺镁引发的黄叶症状,显著增加水稻有效穗数和每穗粒数,进而显著提高稻谷产量。生产上建议在缺镁或镁养分含量较低的水田适量施用硫酸镁肥,每667m2施用量6~16 kg能提高稻谷产量,增加收益。Magnesium deficiency causes leaf etiolation and yield depression for rice.The test of different amount of magnesium fertilizer application was conducted,and the effect on agronomic traits and yield of Zhongzhe 8 were investigated.Results showed that magnesium sulfate fertilizer relieved leaf etiolation induced by magnesium deficiency,increased effective panicle number,spikeletes number and grain production.Magnesium fertilizer is recommended application in field land that magnesium content is lower,magnesium fertilizer 6 to 16 kg per 667m2 could increase yield and benefits.
