近年来,南斯拉夫玉米杂交种Sc_(704)在我区的推广面积逐年扩大,1988年达到120万亩以上,已成为我区中晚熟玉米的主栽品种。 我区从1978年开始引进南斯拉夫玉米杂交种,共引进20个品种。其中单交种12个,双交种3个,三交种5个,连续三年进行区域试验和生产示范。1979年在10个区试点中,Sc_(704)在8个点超过对照,比对照增产21—54％,各点亩产均在千斤以上;1980年各点平均亩产1365.7斤,比对照增产14—42.3%;1981年各点平均亩产1611斤,比对照增产50.3％。该品种除增产显著外,适应性,抗
In recent years, Yugoslavia corn hybrids Sc_ (704) in our region to promote the area has expanded each year in 1988 to 120 million mu or more, has become the main varieties of late-maturing corn in our region. Since 1978, our district has introduced Yugoslavia corn hybrids and introduced a total of 20 varieties. Among them, 12 are single cross, 3 are double cross, and 5 are cross-breed. They carry out regional experiments and production demonstration for three consecutive years. In 1979, in 10 plots, Sc_ (704) surpassed the control at 8 points and increased 21-54% compared with the control. The average yield per mu was above 1 kg in 1980; the average yield per mu was 1365.7 kg in each point in 1980, 14 - 42.3%. In 1981, the average mu yield was 1,611 pounds, an increase of 50.3% over the control. In addition to the variety of significant yield, adaptability, resistance
