摘　　要：为分析沼液对王草(Pennisetum sinese)生产性能和品质的影响,通过采用单因素设计,对雷州半岛越冬期王草进行处理,即施羊粪沼液(A1)、施尿素(A2)和不施肥(CK)。结果表明:1)两次刈割A1组处理下王草鲜干比分别为3.17和3.84,均显著低于其他处理组(P<0.05),A2组与CK组的差异不显著(P>0.05);同期处理下王草A1组的株高和增长率均显著高于A2组和CK(P<0.05),A2与CK差异不显著(P>0.05);同期处理下各处理间王草的茎叶比差异不显著(P>0.05);2)同期处理下A1组王草的粗蛋白和粗脂肪显著高于A2组和CK(P<0.05);A1组和A2组的粗纤维、粗灰分和无氮浸出物较CK显著降低(P<0.05),且A1组与A2组差异显著(P<0.05)。综上认为:羊粪沼液处理可有效改善越冬期王草的生产性能和品质。A single factor design was used to treat king grass(Pennisetum sinese)with different fertilizers,sheep manure biogas slurry(A1),urea(A2),and no fertilizer(CK),to study the effect of biogas slurry on the production performance and quality of king grass in Leizhou peninsula in winter.The results showed that the fresh/dry ratio of grass in the A1 and A2 groups was significantly improved.The fresh/dry ratio of group A1 was 3.17/3.84,which was significantly lower than that of the other treatments(P<0.05),but there was no significant difference between the A2 and CK groups(P>0.05).The plant height and growth rate of group A1 were higher than those of the A2 and CK groups(P<0.05).The stem/leaf ratio was not significantly different in the A1,A2,and CK groups(P>0.05).The crude protein(CP)and ether extract(EE)of group A1 were significantly higher than those of the A2 and CK groups(P<0.05).The content of crude ash(Ash),crude fibre(CF),and nitrogen free extract(NFE)showed a significantly decreasing trend in the A1 and A2 groups compared to that in the control group(P<0.05).In conclusion,the application of sheep manure biogas slurry can effectively increase the production performance and improve nutrition quality of overwinter king grass.
