chinois. 以超级杂交稻培杂泰丰和超级常规稻玉香油占为材料，在大田条件下，研究机械同步深施肥不同施肥量对直播水稻群体质量和产量的影响。结果表明，在0～1 500kg/hm2范围内，施肥可以显著增加培杂泰丰和玉香油占的收获产量、单位面积穗数和每穗实粒数；可以显著增加水稻株高和叶面积指数，提高叶片SPAD，增加干物质积累总量，从而明显改善水稻群体质量。

Effects of deeply mechanized fertilizer application on the quality and grain yield of direct seedling rice were studied using super hybrid rice Peizataifeng and super inbred rice Yuxiangyouzhan as samples in field trials. The results showed that grain yields were increased significantly when the increase of rice special fertilizer rate ranged from 0 to 1 500 kg/hm2. The number of effective panicle per m2 and solid grain per panicle were increased. More application of rice special fertilizer would increase plant height, index of leaf area, SPAD in sword leaf at late stage, and total dry mass weight of rice. The results indicated that deeply mechanized fertilizer application can improve quality of rice significantly.
