| 摘 要： | 采用联合国粮农组织(FAO)推荐的方法,通过光温系数的修正,计算了甘肃河西走廊单作小麦、单作玉米、单作豌豆、小麦间作玉米、豌豆间作玉米等5种作物种植模式的光温潜力.结果表明,大多数单作种植模式不能充分利用光热资源,间套作种植可以衍生作物覆盖时间,当前主要的作物间套作种植模式(小麦间作玉米、豌豆间作玉米)更有利于热量资源的充分发挥

| Abstract: | We use the method recommended by The UN Food and Agriculture Organization(FAO),recommended amendment to the light and temperature coefficient to calculate light and temperature potential of cropping pattern of sole wheat monoculture corn,monoculture pea,wheat intercropping corn,peas intercropping maize in the Hexi corridor of Gansu province.The results showed that the most monoculture cropping patterns can not make full use of light and heat resources,intercropping planting can be derived from the crop to cover the time,the main crop intercropping cropping patterns is more conducive to the full heat resources play which wheat intercropping corn and pea intercropping maize. |
