田间配置模式对套种食用型向日葵光合特性与产量的影响

Effects of Field Allocation Patterns on Photosynthetic Characteristics and Yield of Interplanting Edible-sunflower

以食用型向日葵杂交种"辽嗑杂6号"为试材,在22 000株/hm2密度下,设计4种不同田间株行距配置模式,研究以西瓜为前茬,套种食用型向日葵群体的光合特性和籽粒产量的效应,为西瓜套种食用型向日葵实现高产优质提供合理的田间株行距配置模式。结果表明:M4(大垄双行交错单株)栽培模式下的食用型向日葵表现最优,群体的叶面积指数、干物质积累量、光合势、籽粒性状和籽粒产量等均优于其它栽培模式。

The field experiment was conducted to observe the affect of interplanting of watermelon with edible-sunflower“liaokeza4”on physiological characteristics and grain yield in different configuration modes.The plant density was22000plants/hm2.Result from the experiment showed the leaf area index,leaf area duration,dry matter accumulation and yield of mode M4were higher than those of M1,M2and M3.
