摘　　要：采用径流小区试验,分析了红壤坡耕地香根草(Veiveria zizanioides)篱对生育期内花生(Arachis hy-pogaea)植株高、叶绿素含量和花生产量的影响,探讨篱农间作最佳草篱间距。结果表明,与常耕相比,香根草篱处理苗期篱上第1行花生株高和叶绿素含量显著升高,开花期时株高显著升高(P<0.05),叶绿素含量却显著下降,结荚期株高和叶绿素含量都显著下降,其它各行无明显差异(P>0.05);香根草篱处理篱上第1、2行花生产量显著降低,第5、7、9行则显著升高,而第3、11行无明显差异。研究认为香根草篱与花生的安全距离≥66cm,在此基础上,采用抛物线模型+直线平台分析得知香根草篱间距为8～12m时,间作花生产量与常耕相比基本持平,间套优势明显。A runoff plot experiment was carried out to study the effects of veiveria ainzanioides hedge on peanut plant height,chlorophyll content and yield in different peanut growth periods in red soil sloping land to explore the appropriate space between hedges and crops.The results showed that compared with the conventional tillage treatment,the first line peanut plant height and chlorophyll content increased significantly（P0.05） at seedling period of the veiveria ainzanioides hedge treatment;however,the plant height increased significantly while chlorophyll content decreased significantly at flowering period;the plant height and chlorophyll content both decreased significantly at podding stage.There were no significant differences between other lines（P0.05）.The yields of peanut in line 1 and 2 decresed significantly,but the yield in line 5,line 7 and line 9 increased significantly.We thought that the safety distance between vetiver grass hedgerow and peanut should be≥66 cm,and the appropriate spacing of V.zizanioides hedge is 8 to 12 m by using the parabolic model＋straight platform.There was no significant difference in peanut yield between intercropping and pure cultivation,however,the advantages of intercropping was obvious.
