| 摘 要： | 2002—2003年连续两年在冀西北半干旱高寒区的两种不同类型的土壤中，对13个玉米品种和4个莜麦品种进行产量和消化能比较研究。结果表明，反交冀丰58在滩地种植产量最高，其次为冀丰503，其最高鲜重产量分别为60000 kg/hm2和56000 kg/hm2，相应干重产量分别为10500 kg/hm2 和9250 kg/hm2。9244莜麦在滩地种植其产量高于其它3个莜麦品种，鲜重产量最高达32852 kg/hm2，相应干重产量为8377 kg/hm2。玉米和莜麦两种作物混合比较，在滩地种植的反交冀丰58玉米的消化能处于第一位。在降水一定的年份，同样的栽培条件下，滩地的储水量大，耗水量小，玉米和莜麦在滩地的水分利用率均高于沙地，这也是两种作物滩地产量高于沙地产量的原因。

| Abstract: | Between 2002 and 2003, yield and digestible energy of 13 Maize varieties and 4 oat varieties used as Forage Grass were compared in Different Soil in JI Northwest Dryland. The result showed that Yield of FANGJIAOJIFENG58 was highest, the second was JIFENG503. their highest yield were 60000 kg/hm2 and 56000 kg/hm2. Dry yield were 10500 kg/hm2 and 9250 kg/hm2. Wet yield of oat 9244 and dry yield were 32852 kg/hm2and 8377 kg/hm2 in bottomland, which were highest among 4 varieties. Digestible energy of FANGJIAOJIFENG58 was highest among all those varieties. In a certain year, in the same planting condition, bottomland can save more water, and used up less, which is another reason for highest yield in bottomland. |
