摘要
研究了雁门关农牧交错带不同一年生牧草及饲料作物混播草地的产草量。结果表明,燕麦Avenasa-tivacv.Lena与豌豆Pisumsativum1∶1比例的混播组合产草量和粗蛋白产量最高,分别达48 525和1 981 kg/hm2。燕麦与豌豆混播时,行距以30 cm为宜,粗蛋白产量隔行播种明显高于同行。饲用玉米Zeamays与拉巴豆Dolichos lablab混播以及高丹草Sorghumvulgare×S.sudanense与拉巴豆混播均比饲用玉米和高丹草单播产草量高。在平川、盆地地区此种植模式能取得较高的青饲料产量,而燕麦与豌豆混播种植模式适于在山地以及丘陵地区种植。
The yield of the annual forage and feed crops mixture grassland in agro-pastoral transitional zone of Yanmenguan region in Shanxi was studied. The results showed that the mixture with 50% common vetch ＋ 50% oat was the best among the different mixtures, the yields of grass and crude protein reached 48 525 kg/hm^2 and 1 981 kg/hm^2, the suilable row spacing was 30 cm, the crude prorein of interlacing sowing significanlly was higher than the same row sowing. While the grass yields of mixtures with 50% corn ＋ 50% lablab or 50% sorghum hybrid sudangrass＋ 50% labia were higher than the single sown of corn or sorghum hybrid sudangrass. The models could get higher grass yield in flat ground and basin region, and the mixture model of oat and vetch was suitable adopted in mountain and hilly region.
