摘　　要：研究了坡耕地玉米马铃薯不同种植模式(玉米马铃薯2∶2间作、玉米马铃薯4∶4间作、马铃薯单作、玉米单作)对蓄存田间水分的影响。结果表明,在相同的自然水分条件下,玉米马铃薯4∶4间作处理的水分利用率较高且存蓄较多水分。因此,坡地上合理的间作方式能蓄存水分,其中4∶4间作处理蓄存水分较多。该研究对保护坡耕地生态环境和解决广西粮食安全具有一定的指导意义。Effects of corn and potato intercropping modes(maize potato 2∶2,maize potato 4∶4,maize sole cropping and potato sole cropping)on storing field moisture in slope cropland were researched.Results showed that under the same natural conditions,maize potato 4∶4 intercropping treatment could store more water and had relatively higher water use efficiency.Therefore,reasonable intercropping in slope cropland could store moisture.And the 4∶4 intercropping treatment showed relatively greater water reservoir capability.This research showed certain guiding significance for the protection of the ecological environment and for solving the food security in Guangxi.
