| 摘 要： | 在丘陵红壤旱地花生主产区,以花生、木薯纯作为对照,通过不同花生木薯间作研究了木薯对花生负面空间影响距离和木薯间作适宜行距,及间作木薯对土地利用率的影响。结果表明:花生间作木薯(不明显降低花生产量的前提下)种植系统中木薯对花生的负面影响空间距离为40 cm左右,木薯间作适宜行距不低于374 cm;且花生木薯宽行间作可明显提高丘陵红壤的土地利用率,纯收入提高58.3%。

| Abstract: | Taking the pure cropping of peanut and cassava as the check,peanut-cassava intercropping experiment was conducted to studied the suitable spacing between peanut and cassava,the negative effect of cassava on peanut,as well as the influence of the intercropping upon land utilization rate in hilly red soil upland.The results showed that: in peanut-cassava intercropping system in which the peanut yield was not obviously reduced,cassava had significant negative effect on peanut yield when their spacing was less than 40 cm,and the suitable row spacing of the intercropped cassava was more than 374 cm.Peanut-cassava wide-row intercropping could significantly improve the land utilization rate,and it could advance the net economic benefit by 58.3%. |
