通过对不同品种的密度试验，结果表明：半耐密型品种适宜种植密度在50 000～55 000株/hm²；耐密型品种适宜种植密度在55 000～65 000株/hm²。在适宜播种密度范围内，子粒百粒重和容重与收获密度呈负相关，收获时子粒含水率与密度呈正相关。

Density trial of several varieties were tested, the results showed that the fitting plant density of semi close-enduring planting maize variety was 50 000 - 55 000 plants/ha, close-enduring planting variety was 55 000 - 65 000 plants/ha. In the fitting plant density, the weight of 100 kernels and volume weight were showed negative correlation to harvest population, and the water content of harvest kernel was showed positive correlation to harvest density.
