摘　　要：以晋花7号花生为材料,研究幼龄核桃园间作条件下,不同种植带与树干距离对间作花生生长发育及产量的影响。结果表明,当树冠大小约为1.90 m,种植带与树干距离为90 cm,即种植带与树干距离约为冠幅半径时,间作对花生的生长发育及产量无明显影响,其理论产量最高,达到5387.43 kg/hm^2。In this study,the effect of different planting belt and trunk distance on the growth and yield of peanut intercropped in young walnut garden was studied with Jinhua 7 peanut as material.The result showed that when the crown size was about 1.90 m and the distance between planting belt and trunk was 90 cm,that is to say,the distance between planting belt and trunk was about the crown radius,intercropping had no obvious effect on the growth and yield of peanut,and its theoretical yield was the highest,reaching 5387.43 kg/hm^2.
