摘要
采用普通玉米杂交种或其同型雄性不育杂交种与高油玉米相间种植的方式，以提高普通玉米杂交种的产油量。结果表明，在高油115与普通杂交种农大108、雄性不育豫玉22号、雄性不育农大3138相间种植比例为2：4、密度48000株／hm^2的条件下，普通玉米杂交种比高油玉米平均增产26．5%，比对照增产10．6%；雄性不育玉米杂交种比高油玉米增产25．2％，比对照增产31．6％；普通玉米杂交种、雄性不育杂交种和高油玉米的籽粒含油率平均为8．1％，8．1％和8．3％，而对照为4．2％～4．3％。
Intercropping of high-oil corn hybrids with either common corn hybrids or male-sterile corn hybrids was practiced to increase the oil output of the latter. The results showed that the reasonable intercropping ratio of Gaoyou 115 with common corn hybrid Nongda 108,male-sterile corn hybrid Yuyu 22,or male-sterile corn hybrid Nongda 3138 was 2 ： 4,and the suitable planting density was 48000 plants/ha. The grain yield of common corn hybrids increased averagely by 26.5% and 10.6% over high-oil corn hybrids and CK,respectively. The yield of male-sterile corn hybrids increased by 25.2% and 31.6%~ in average over high-oil corn hybrids and CK,respectively. Average oil content of common corn hybrids, male-sterile corn hybrids, and high-oil corn hybrids was 8.1%,8. 1%,and 8.3%,respectively,while that of the CK was 4.2%-4.3%.
