华北平原南部一年两熟区不同搭配作物光合性能比较研究

摘要:
为了探寻华北平原南部一年两熟制中较适宜的搭配模式,研究了该区域广泛应用的:小麦-玉米、小麦-大豆、小麦-花生、小麦-甘薯4种搭配模式,分析了不同模式光合性能的变化规律,计算了其光资源利用效率及产量与产值.结果表明:小麦-甘薯模式在两季的总光资源积累量中表现出最高;但由于小麦-甘薯模式价格最低,所以其两季的总产值最低.另一方面,小麦-玉米、小麦-大豆、小麦-花生3种搭配模式由于生育期基本一致使得其光能积累几乎相等;而小麦-甘薯模式在除小麦-玉米模式的其他3种模式中光合作用强度较高,光能利用效率仅次于小麦-玉米模式,加之产品价格较高,故两季的总产值最高;此外,小麦-花生模式在光资源利用效率以及总产值方面也具有相对的优势.因此选择小麦-玉米模式作为华北平原南部两熟区最适宜的搭配模式,而小麦-花生模式可作为该地区的替代搭配模式.
In order to explore the suitable planting patterns in the southern region of the North China Plain,we studied the variation changes of light resources of different planting patterns through four widely used cropping patterns:wheat-maize,wheat-soybean,wheat-peanut,wheat-sweet potato.Based on the investigating the solar resource distribution and yield in different double-cropping,the solar utilization efficiency,and production value was calculated.The results showed that the distribution of solar resource in different collocation patterns was different due to the sowing and harvesting time.Because the interception rate of canopy photosynthetically active radiation in the late growth stage of sweet potato was significantly higher than other patterns,the total daily accumulation of wheat-sweet potato pattern was the highest among the four patterns,although which in wheat season was the lowest one due to the last harvesting time of fore-rotating sweet potato.However,since the price of sweet potato was much lower than other crops,wheat-sweet potato pattern got the lowest total production value of two seasons.On the other hand,the solar accumulation of wheat-corn,wheat-soybeans and wheat-peanuts were almost equal to each other.Furthermore,the photosynthetic rate and the solar utilization efficiency of wheat-maize pattern,as well as the price were higher than the other three planting patterns so that the production value of this pattern reached the top.Additionally,the wheat-peanut pattern ranked only second to the wheat-maize pattern on the solar utilization efficiency and total output value.Therefore,the wheat-maize pattern is chosen as the best suitable collocation pattern in this double-cropping area in the southern of North China Plain,and the wheat-peanut pattern could be used as an alternative collocation pattern in the region.
