沼渣在棉花上的施用效果初探

Effects of Biogas Dregs to Cotton

通过田间试验，初步探讨了沼渣在山西省临猗县棉花上的肥效。结果表明：棉花基施沼渣、猪粪能够改善棉花的生物学性状，主要表现为叶片增厚增大、光合作用增强、脱铃率降低、铃重和衣分增加，为提高产量打下了基础。基施沼渣3．0万kg／hm^2，比对照增产27.4％-27．9％；基施沼渣1．5万kg/hm^2，比对照增产6．8％-10．4％。

The field experiments were conducted on the effects of biogas dregs to yield and quality of cotton in Linyi county of Shanxi province. Results indicated that biology characters of cotton were improved by using biogas dregs and leaves thickness was increased, and photosynthesis of cotton was also improved. Compared with the traditional treatments,30 000 and 15 000 kg/hm^2, application of biogas dregs can increase yield of cotton by 27.4%-27.9% and 6.8%-10.4% respectively.
