通过连续3年两基点的定位试验研究,结果表明:在良好的水肥条件下,小麦玉米玉米间套作种植模式是实现高产高效、提高光热资源利用效率的有效途径。2.5m和3.0m种植带宽3年平均每公顷产粮19151.7kg,比小麦玉米一年两熟平作增产32.81%;小麦玉米玉米间套作种植模式全生育期和全年的光能利用率为1.7%和1.64%,比小麦玉米一年两熟平作提高了16.05%和18.98%,而且全年≥0℃积温的热量利用接纳系数和≥10℃积温每℃可生产粮食分别提高了14.35%和26.13%。
The results of two years’ experiment of two-point positioning showed that under the condition of good water and fertilizer, the wheat-corn intercropping pattern was an effective way to realize high yield and high efficiency and increase utilization efficiency of light and heat resources. 2.5m and 3.0m planting bandwidth 3 years average yield of 19151.7kg per hectare, compared with wheat and wheat two crops a year to increase yield 32.81%; wheat and corn intercropping plantation mode throughout the growth period and year-round light The utilization rate was 1.7% and 1.64%, which was 16.05% and 18.98% higher than that of wheat and corn two crops a year, and the heat gain≥0 ℃ during the whole year was calculated by using the acceptance coefficient and ≥10 ℃ Accumulated temperature per food can produce grain increased by 14.35% and 26.13%.
