| 摘 要： | 通过田间试验,初步研究了不同施肥方式对冷浸田早稻产量的影响。结果表明:当施肥方式为基肥∶蘖肥∶穗肥=7∶3∶0时,早稻的有效分蘖数、每穗总粒数、千粒重和产量均最高,且对氮、磷、钾肥的利用率也均高于其它施肥方式。

| Abstract: | The effects of different fertilization modes on the yield of early rice in cold waterlogged field were initially studied through field test.The results indicated that: when base fertilzer∶tillering fertilier∶spike fertilizer was 7∶3∶0,the early rice got the highest effective tillers,total grains per spike,1000-grain weight and grain yield,and the use rates of N,P and K fertilizer were also higher than those in other fertilization treatments. |
