【摘要】 在枣棉间作条件下设置135000、180000、225000、270000和315000株/hm25个棉花密度水平,研究不同处理对棉花干物质积累和产量性状的影响。结果表明:随着种植密度的增加棉花株高、果枝数、结铃数呈下降趋势,以密度225000株/hm2皮棉产量最高。结合生产实际,南疆枣棉间作条件下棉花适宜种植密度为225000～270000株/hm2。更多还原

【Abstract】 In this paper,the effect of different planting densities(135000、180000、225000、270000、315000 plant /hm2) on cotton dry matter accumulation and yield were studied in the pattern of jujube and cotton intercropping.The resultsindicated that: plant height,fruit branch number and boll number were all declined with the increase of planting density;Lint yield was the highest when plant density was 225000 plants/hm2.Connecting with the production practice,the author considered that the optimal planting density was 225000-270000 plants /hm2 in the pattern of jujube and cotton intercropping in southern Xinjiang cotton region.更多还原
