【摘要】 对5个不同种植密度处理下2个矮秆蓖麻品种含油量与个农艺性状态进行相关及通径分析.总结出不同密度水平下,影响矮秆蓖麻含油量的主要农艺性状,并提出提高密植矮秆蓖麻的含油量,一定要主攻容重,在增加容重的基础上增加株穗数,并选择适中的株高、茎粗及主穗与一级分枝夹角.更多还原

【Abstract】 through the analysis of 5 different planting densities of 2 dwarf castor varieties of oil content and agronomic state correlation and path,it could be summarized that the main agronomic traits of dwarf castor oil content in different density level, and be put forward improving oil content close planting dwarf castor-oil plant,and the bulk density must be the main part, increasing on the number of spike per plant based on increased bulk density, and choose the moderate plant height, stem diameter and main spike and a branch angle.更多还原
