摘    要:在玉米不同种植密度群体中初步研究了玉米群体的自动调节与补偿。结果表明,玉米群体在一定的密度范围内具有较强的自动调节能力。群体在叶面积上的自动调节能力较弱,而在干物质生产上的自动调节能力则较强。群体的自动调节作用对生殖器官的影响大于对营养器官的影响。产量因素的自动调节作用是生长后期的产量因素补偿生长前期损失的产量因素。

关 键 词:玉米  冠层结构  自动调节  产量

Abstract:Automatic regulation and compensation mechanism of corn populations with different densities were studied. The results showed that the corn population had strong automatic regulation during some plant densities. The automatic regulation was weak on the leaf area of corn population, but the automatic regulation was strong on the dry matter production .The effect of automatic regulation on procreation organ was higher than nutrition organ. The effect of automatic regulation on the yield was the later production yield factors that compensated the loss of before factors.
Keywords:Study on Automatic Regulation and Compensation Mechanism of Corn Canopy Construction
