摘要:

为探明柯杈肥与功能肥对杂交稻生长发育及产量的影响,开展裂-裂区试验,其中,主区为普通复合肥(F1)和柯杈肥(F2);裂副区为喷清水(P1)和喷植物生长调节剂(即功能肥)(P2);再裂区为6个杂交稻品种。结果表明:柯杈肥与功能肥复配使用能有效促进分蘖早生快发和叶面积指数增加。在6个品种中,隆两优1813在F2P2处理下的产量最高,达12 512.04 kg·hm-2。对6个品种来说,均以F2P2处理的产量最高,且显著(P<0.05)高于F1P1处理,增产幅度在30.02%~70.48%。总的来看,柯杈肥与功能肥复配使用通过提高各品种的有效穗数、结实率、千粒重有效促进了水稻产量的提升。

Abstract:

To investigate the effects of branch fertilizer and functional fertilizer on the growth, development and yield of hybrid rice, the split-split plot design was used in the experiment. The main plots were common compound fertilizer (F1) and branch fertilizer (F2). The split area was divided as spraying water (P1) and spraying plant growth regulator (functional fertilizer) (P2). The re-splitting area was 6 hybrid rice varieties. The results showed that the co-application of branch fertilizer and functional fertilizer could effectively promote the early growth and tillering and increase the leaf area index. Among the 6 varieties, Longliangyou1813 exhibited the highest yield (12 512.04 kg·hm-2) under the F2P2 treatment. For all the 6 varieties, the highest yield was all found under the F2P2 treatment, which was significantly (P<0.05) higher than that under the F1P1 treatment by 30.02%-70.48%. In general, the co-application of branch fertilizer and functional fertilizer enhanced the rice yiled by increasing the effective panicle number, seed setting rate and 1 000-grain weight.
