| 摘 要： | 不同杂交玉米组合、不同群体密度试验于1996－1997年进行，在不同密度下各组合的产量和穗粒性状差异不显著，密度对半紧凑型玉米的叶面积和干物重及净同化率等性状的调节作用比紧凑型玉米掖单12号要大些，根据广东的情况，从各方面性状综合考虑，半紧凑型玉米以4.5×104～6.0×104株／hm2为宜，而紧凑型玉米掖单12号以7.5×104株／hm2左右为宜，

| Abstract: | Different plant types of hybrid maize were experimented in different populations from 1996 to 1997.The results showed that the yield charecteristics of rnaise were better in fow density than in high density, bUt thase differences did not mech a significant level.The leaf area and dry matter as well as net assimilation rate of the close plant tyoe of maize did not response to the density varience as the half-close type of maize in different plant growth periods.The suitable population was suggested that the close type of maize was 75 000 plant/hm2 and the half-close type was 45 000 t0 60 000 plant/hm2. |
