| 摘 要： | 在贵州高原山区特定生态条件下,研究了种植密度对3种株型玉米产量和群体质量的影响,结果表明:3638、S9914、方玉2号的适宜密度分别5.985万～8.50万株/hm2、6.12万～9.6万株/hm2、5.37万～8.355万株/hm2;种植密度对3种株型玉米的叶面积系数、干物质分配比例、光合势和净同化率等群体质量也有不同的影响;紧凑型玉米和半紧凑型玉米对密度的压力反应小,而平展型玉米对密度的压力反应大。 |

| Abstract: | In the special ecological condition of mountain area of Guizhou, Effects of plant density on yield and colony quality of three different plant types corn were studied. The results show that the best density of 3638 is 59 850-85 000 plants per hektare, S9914 is 61 200-96 000 plants per hektare, FangYu 2 is 53 700-83 550 plants per hektare .Different effects of plant density on LAl,dry matter distribute proportion, LAD, NAR. The force response on plant density of compact corn and semi-compact corn is small and plate corn is big. |
| Keywords: | Corn Plant types Plant density Colony quality Yield |
