摘  要：
在桑科草原设置施肥和补播处理,分析不同经济类群生物量、营养成分及载畜量的差异,以探讨不同培育措施在短期内对桑科草原载畜能力的影响。结果表明:培育措施对不同测算标准下的草地载畜量均有极显著的影响(P<0.01),施肥和补播处理对干物质(DM),总载畜量(246.81和239.80羊单位/hm~2)和可消化粗蛋白(DCP)总载畜量(133.50和124.89羊单位/hm~2)有较好的促进作用,分别比对照(CK)增长了33%、30%、20%和12%;对代谢能(ME)载畜量(210.83和213.22羊单位/hm~2)的促进作用较小,仅比CK增长了0.2%和1%。处理当年,补播对禾本科草类DM和DCP载畜量的增加最有利,施肥对生长季后期DCP载畜量的促进作用较明显。

摘  要：
In order to investigate the short-term effects of different cultural treatments on the carrying capacity of Sangkok,as well as analyze the theoretical differences of carrying capacity based on various standards,the biomass,nutritional indigent and carrying capacity of different economic groups under fertilizing and reseeding treatments in this area were studied.Results showed that the carrying capacity based on different measurement standards under fertilizing and reseeding was significantly different(P<0.01).The DM carrying capacity(246.81 and 239.80 sheep unit/hm~2)and DCP carrying capacity(133.50 and 124.89 sheep unit/hm~2)were promoted under fertilizing and reseeding treatments,with each increased by 33%,30%,20% and 12% compared with CK,respectively;the slightly promoted ME carrying capacity(210.83 and 213.22 sheep unit/hm~2)increased by 0.2%and 1%compared with CK,respectively.In the first year of treatment,the DM and DCP carrying capacity of Gramineae grasses under reseeding was increased greatly,and DCP carrying capacity under fertilizing in the later stage of growth season was improved obviously.To achieve the dual balance between production and ecology,it is recommended that the grazing in June be set based on DM carrying capacity,and that in July,August and September based on DCP carrying capacity.
