摘    要:以青花7号花生品种为材料,在田间地膜覆盖栽培条件下,系统研究了不同种植密度对花生群体透光率的影响。结果表明:随种植密度的增加,垄上行间和垄间上、中、下部的透光率均呈递减趋势。通过垄上行间和垄间中后期透光率的变幅大小分析,认为本试验种植密度以15万穴/hm2群体内光照分布较为合理。

关 键 词:花生  种植密度  群体  透光率

Abstract:Peanut cv.Qinghua 7 was used to systematically study the effects of planting density on the light transmittance of peanut population with film mulching in field.The results indicated that with the increase of planting density,the light transmittance reduced at upper,middle and lower parts between lines on ridge and between ridges.The light distribution in the population was more reasonable at the planting density of 150 000 holes per hactare based on the amplitude analysis of light transmittance between lin...
Keywords:Peanut  Planting density  Population  Light transmittance
