摘要
本文作者在天祝县金强河甘肃农业大学天祝高山草原试验站进行了燕麦与豌豆混播的组合试验,其组合比例A处理各占单播量的50％、B处理各占单播量的35％+65％、C处理各占单播量的20％+80％.D处理为对照。试验结果表明,干草产量以A处理(790.8克/平方米),B(781.2克/平方米)、C(728.9克/平方米)>D(584.5克/平方米)。鲜干比以A为3.2:1,B为3.7:1,C为4.0:1,D为3.1:1。日平均生长量A为5.86公斤/亩,B为5.79公斤/亩,C为5.40公斤/亩,D为4.33公斤/亩。依各项测定指标的综合评定,筛选出A和B处理是高寒牧区较为适宜的混播组合。
The writers of the paper conducted the combinating experiment of mixture on oats with pea at the experimental station of the alpine grassland of Gansu agricultural university at Jin Qiang river area in Tianzhu county. The ratios of the combination were as fellows: treatment A was that oats and pea made 50％ of their single cultive amounts separately, B was oats 35％+pea 65％, C was oats 20％+pea 80％, D was the comparing treatment. The results of the experiment shewed that the yields of the hay of the different treatment were 790.8g/m2(A), 781.2g/m^2(B) and 728.9g/m^2>(C)584.5g/m^2(D), The ratios of fresh weight to hay weght were 3.2:1(A), 3.7: 1(B), 4.0:1(C), and 3.1:1(D). As to the daily average growth amount per MU. A was 5.86kg, B 5.79kg, C 5.40kg and D 4.33kg. Treatment A and B were more suitable combination of mixture in the cold postoral areas based on combinating evaluating to the various taroets measured.
