对红花标记杂交棉鲁05 H9的不同种植密度、施肥方式进行大田小区试验，结果表明，在鲁西区域土质粘壤土、肥力中等条件下，鲁05H9种植密度3．6万株/hm2且缓控释肥用量750 kg/hm2时能够获得最高纯收益；缓控释肥与常规施肥处理籽棉、皮棉产量均差异不显著，纤维品质有所提高，这符合棉花简化栽培的要求。

Different planting densities and fertilization modes of red -flower marked hybrid cotton Lu 05 H9 were studied in Luxi area .The results showed that , under clay soil and medium soil fertility conditions , Lu 05 H9 had the highest net income when the planting density was 36 000 per hectare and the fertilizer appli-cation amount was 750 kg/hm2 .The seed and lint cotton yields of slow controlled release fertilization had no significant difference to that of conventional fertilization , but the fiber quality improved .This planting pattern conformed to the demand of simplified cultivation of cotton .
