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.
