| 摘 要： | 以鲁棉研28为试材,在冀南地区研究了不同种植密度对棉花生长发育及产量品质的影响。结果表明：随密度增加,棉花株高、单株铃数、单铃重呈下降趋势,伏前桃比例增加而伏桃比例降低,单位面积铃数、皮棉产量先增加后降低;8.7万株/hm2时皮棉产量达到最大值,但在5.1万株/hm2到10.5万株/hm2之间皮棉产量差异不显著;密度对衣分和纤维品质影响不大;多雨年份,不同密度棉花株高、单铃重、衣分和皮棉产量均高于干旱年份,低密度成铃率高而高密度成铃率低。

| Abstract: | With SCRC 28 as material,the effects of different planting densities on the growth and development,yield and fiber quality of cotton were studied in south area of Hebei.The results were as follows.With the increase of density,the plant height,boll number per plant and boll weight decreased;the ratio of pre-summer bolls increased but the ratio of summer bolls decreased;the boll number per unit area and lint yield increased until the density reached 87 000 plants per hectare,but there were no significant diff... |
