我县陶村大队主任刘彦恒棉花科研小组,1978年搞了4.2亩棉花高产试验田,平均亩产皮棉324.4斤,其中稀棵密茎开心型棉花亩产皮棉355.6斤。这种棉花在田间的特点是:看个体,主茎低、油条高,株株都象聚宝盆;看群体,株数少(每亩3,000株)、茎数多(每亩8,000多茎),稀棵密茎“圪塔”多。稀棵密茎开心型棉花有5大优点:一是个体健 Liu County, Taoxing County team director Liu Yanheng cotton research team, in 1978 engaged in 4.2 acres of cotton yield test field, the average mu produce 324.4 kg of lint, of which thin stems happy stem type cotton per mu lint 355.6 kg. The characteristics of this cotton in the field are: look at the individual, the main stem is low, the dough is high, the strains are like cornucopia; see groups, the number of plants (3,000 per acre), stems and more (8,000 acres per acre) Dense stem “圪 tower” and more. Slightly thin stem happy cotton has five major advantages: First, individual health
