Space influence of Veiveria zizanioides hedge on peanut growth in red soil sloping land

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). 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.
