摘要
在江汉平原对丰两优2号、丰两优香1号、两优168、国丰1号、荃优801、皖稻107等6个水稻品种施用尿素100kg/hm 2作穗肥,调查供试品种的农艺性状、产量和经济效益的变化,结果表明:追施穗肥后水稻全生育期、株高、穗长、剑叶长、剑叶干重均显著增加;追施穗肥会显著增加每穗粒数和粒重,但存在品种差异,丰两优香1号、国丰1号、丰两优2号、两优168追肥后产量增加,荃优801、皖稻107追穗肥后未能增产;追施穗肥的效益也存在品种差异,丰两优香1号、国丰1号、丰两优2号和两优168追穗肥可增加水稻效益,两优168增幅最高(17.0%),荃优801、皖稻107追肥后经济效益未能增加。
Urea 100kg/hm 2 is used as panicle fertilizer to the six rice varieties of Fengliangyou 2,Fengliangyouxiang 1,Liangyou 168,Guofeng 1,Quanyou 801 and Wandao 107 in the Jianghan Plain,the changes of agronomic traits,yield and economic benefits of the cultivars are investigated.The results show that:in the whole growth period,plant height,ear length,flag leaf length and dry weight of the flag leaf of the rice increase significantly after the application of panicle fertilizer;the number of grains per panicle and grain weight significantly increase,but there rea differences in varieties.The yields of Fengliangyouxiang 1,Guofeng 1,Fengliangyou 2 and Liangyou 168 increase after the topdressing,the increase of Liangyou 168 is the highest(17.0%)and Quanyou 801 and Wandao 107 do not increase in yield after fertilizer application;there are also differences in the benefits of applying panicle fertilizer.Fengliangyouxiang 1,Guofeng 1,Fengliangyou 2 and Liangyou 168 can increase the efficiency,and the increase of Liangyou 168 is the highest(17.0%).The economic benefits of Yanyou 801 and Wandao 107 do not increase after applying panicle fertilizer.
