摘要
为探索杨树对林下间作物小麦生长的影响,对杨树3种不同配置模式对小麦生物量、小麦品质、小麦产量以及小麦营养与生殖生长关系的影响展开调查和分析。研究表明,杨树不同配置模式对小麦生长影响程度不同,其中以3m×5m×30m配置模式的生物量和产量等指标最高,3m×15m配置模式最低;而小麦出产率则恰恰相反。单穗重、千粒重、蛋白质含量、淀粉含量则以4m×5m×50m模式最大,3m×15m模式最小。3m×15m模式产量和质量的各项指标均较低,而4m×5m×50m模式单位面积所能种植的杨树株数偏少。综合这两个方面的因素考虑,认为3m×5m×30m配置方式是一种比较理想的配置方式。
This paper has analyzed effects of poplar on wheat in three agroforestry management patterns of poplar plantation in plain area of Jiangsu province. Based on the investigation of biomass, yield and cereal quality of wheat,it was found that poplar-crop intercropping affects the wheat growth significantly and such effects varied with the poplar intercropping patterns. The biomass and yield ,of wheat was the highest in the pattern of 3 m × 5 m × 30 m,while the lowest in the pattern of 3 m × 15 m. However,ratio of yield to biomass was on the contrary for the two patterns. The 1 000 grains welght,protein content and starch content of wheat was the highest in the pattern of 4 m × 5 m × 50 m,but lowest in the pattern of 3 m × 15 m. Considering the less poplar trees per hectare in the pattern of 4 m × 5 m × 50 m, we suggests that the pattern with 3 m × 5 m × 30 m is the best poplar-wheat intercropping pattern both from economic and ecological ways.
