为探索棉花合理种植方式和种植密度，进行了稀穴密株种植试验。结果表明：采用稀穴密株种植棉花，不仅可减少劳动力，而且在适宜的密度下可显著提高棉花产量。在种植方式为3株/穴时，棉花的株高比对照增加6.97%，极显著高于对照；在花铃期以前，稀穴密株处理的光合速率都明显高于对照，花铃期以后，稀穴密株种植群体的光合速率下降较快；3株/穴时棉花的单株成铃数比对照增加52.38%，籽棉产量增加25.90%。

The experiment of dense-planting at thin-hole for cotton was carried out to explore reasonable planting method and planting density. The results showed that,using the technology of dense-planting at thin-hole,not only could reduce the labor force,but also could significantly increase cotton production in the appropriate density.When the planting density was 3 plants/acupoint,the cotton plant height increased 6.97% than CK.The photosynthetic rate was significantly higher than CK before the flowering stage,the photosynthetic rate of the plants of dense-planting at thin-hole decreased rapidly after the flowering stage.The number of boll per plant of 3 plants/acupoint cotton increased 52.38%than CK,seed yield increased by 25.90%.
