不同种植密度对中间型大花生花育22号生物学性状与产量的影响

Effects of Different Planting Densities on Biological Characters and Yield of Intermediat-Type Peanut Variety Huayu 22

以中间型大花生花育22号为试材,设9.0万、12.0万、15.0万、18.0万、21.0万穴/hm25个种植密度进行试验,研究其对花生主茎高、总分枝数、单株结果数、双仁果率、双仁饱果率、产量等性状的影响。结果表明,密度在12.0万~15.0万穴/hm2之间能够兼顾高产与商品性的要求。

Five kinds of planting density , 90 tousand , 120 thousand , 150 thousand , 180 thousand and 210 thousand holes per hectare , were designed to study their effects on plant height , total branch number , pod number per single plant , rate of dual-kernel pods and rate of dual -kernel full pods , yield and so on of pea-nut variety Huayu 22.The results showed that the yield and commodity could both been given consideration to under the planting density of 120 thousand^150 thousand holes per hectare .
