棉花不同密度对铃重和衣分的影响

Impacts of Boll Weight and Bell Shell Weight and Lint Percentage Cotton During Different Density

以湘杂棉8号为品种,通过6种不同密度处理试验,研究棉花不同时期不同密度对铃重、铃壳重和衣分的影响。试验表明:棉花单铃重随着密度的增加而逐渐降低,以21000株/hm2单铃重最高,在同一密度处理中,棉花单铃重:中期>前期>后期;棉花的铃壳重随着密度的增加而逐渐降低,在同一密度下,铃壳重都有随着时间的不断推移而逐渐增加的趋势;不同密度处理,各衣分差异不显著,在各个处理的不同生长时期,衣分率先逐渐增加后降低。

The experiment took Xiang za 8 as the same variety, through six treatments of different density, impacts of boll weight and bell shell weight of cotton during different period and different density were studied. The treatment indicated that boll weight of cotton decreased as the density increased, it is the highest boll weight under 12 thousands per hm^2, Dealing with the same density in all, the cotton boll weight alone： medium - term, early, late. Bell shell weight of cotton decreased as the density increased, At the same density, the bell shell weight were constant over time and gradually increase over; The lint percentage were no significant differences under different density, lint percentage increased to reduce in various different growth period.
