在大田条件下,研究了不同类型复合肥料对超级杂交中稻Y两优1号生长发育及产量的影响。结果表明,在等养分用量条件下,与撒可富复合肥(对照)相比,史丹利普通型复合肥有利于Y两优1号分蘖、叶绿素含量、干物质积累及有效穗和千粒重的增加,最终获得较高产量,为12.46t/hm2,比对照增加3.3%。在减少养分用量20%的条件下,史丹利缓释型复合肥处理产量为12.03t/hm2,与撒可富和普通复合肥处理差异不显著,表明史丹利缓释型复合肥适合当地超级杂交中稻生产,且有节肥作用。
Under field conditions, the effects of different types of compound fertilizers on the growth and yield of super hybrid rice Y Liangyou 1 were studied. The results showed that Stanley common compound fertilizer was beneficial to the tillering, chlorophyll content, dry matter accumulation, effective panicles and 1000-grain weight of Y Liangyou 1 compared with the safloxacin compound fertilizer (control) The final yield was higher at 12.46 t / hm2, an increase of 3.3% over the control. Under the condition of reducing nutrient content 20%, the yield of Shi Danli sustained-release compound fertilizer was 12.03t / hm2, which was not significantly different from that of saffron and common compound fertilizer, which indicated that Shi Danli sustained-release compound fertilizer was suitable for the production of local super- , And a fertilizer effect.
