摘要
研究内蒙古农牧交错带不同施肥处理对粮饲兼用玉米品质及产量的影响,对该区域生态农业建设具有重要的意义。试验于2006年在内蒙古呼和浩特市园艺中心试验地进行,设6种不同施肥处理方式,种植作物为玉米(承3359),观测了全生育期不同处理下玉米的粗脂肪、粗蛋白和粗纤维,并进行鲜、干质量及产量的测定。结果表明:有机肥与无机肥配施处理能够提高玉米的粗脂肪含量,完熟时叶、茎、穗分别较不施肥处理提高了19.0%,15.6%,17.4%。有机肥与无机肥配施处理能够提高玉米的粗蛋白含量,完熟时叶、茎、穗分别较不施肥处理提高了16.1%,16.3%,17.8%。有机肥与无机肥配施处理降低了玉米的粗纤维含量,完熟时叶、茎、穗分别较不施肥处理降低18.7%,7.4%,18.4%。有机肥与无机肥配施能够增加玉米秸秆和果穗的产量,收获后玉米的秸秆和果穗的产量分别较不施肥提高了9.1%,16.2%。因此,牛粪+氮肥+磷肥配施可作为农牧交错带提高作物产量和品质的有力措施,同时为农牧复合地带农业和牧业的相互依存发展提供了依据。
The study on the grain forage quality and yield of maize under different fertilization treatments in the farming-pastoral Inner Mongolia.It has great significance of ecological agriculture Construction in this region.We set six different fertilization treatments and carried out in 2006 in Huhhot garden center,Inner Mongolia.We observed crude fat,crude protein,crude fiber,fresh weight,dry weight and yield of maize（Cheng 3359）during the whole growth period in different treatments.The results showed that：Crude fat of maize can be improved in organic and inorganic fertilization treatment,leaf,stem and ear increased 19.0%,15.6%,17.4% by no fertilization treatment in repining time.Crude protein of maize can be improved in organic and inorganic fertilization treatment,leaf,stem and ear increased 16.1%,16.3%,17.8% by no fertilization treatment in repining time.Crude fiber of maize can be decreased in organic and inorganic fertilization treatment,leaf,stem and ear decreased 18.7%,7.4%,18.4% by no fertilization treatment in repining time.Yield of maize straw and fruit ear can be improved in organic and inorganic fertilization treatment,yield of maize straw and fruit ear increased 9.1%,16.2% by no fertilization treatment after harvest.Therefore,cow dung ＋ nitrogen ＋ phosphorus will be a effective measurement to improve crop yield and quality in farming-pastoral region.It can also provide a basis for interdependent development between agriculture and animal husbandry in farming-pastoral region.
