| 摘 要： | 为给大豆优质高产栽培措施提供理论依据,通过对65cm垄作和45cm窄行密植两种耕作栽培方式的研究,探讨了不同耕作模式对垦丰16大豆主要叶部性状生长发育的影响。结果表明:大豆不同耕作模式下单株叶面积、叶面积指数、叶绿素含量及单株叶干重在不同的生育时期均呈先升后降的变化趋势,除叶面积指数外,各项指标均为垄作高于密植,群体密度的大小直接影响着叶片各项生理指标的变化。

| Abstract: | The growth and development of the main leaf traits of Kenfeng 16 were discussed to provide theory basis for good quality and high yield soybean cultivation by studying the two planting patterns of 65 cm ridge and 45 cm narrow row and compact planting.The results showed that leaf area per plant,leaf area index,leaf chlorophyll content and leaf dry weight in different growth stages indicated increased first and then decreased trend.Except of leaf area index,indicators of the ridge were higher than narrow row and compact planting.The changes of physiological indicators in leaves were affected by population density. |
