摘要
对徐淮平原杨粮复合系统内不同物候期生态因子的变化规律进行了研究。结果表明:在杨树展叶期,不同株行距生态因子变化不明显,能满足小麦生长需要;在杨树展叶后的全叶期到盛叶期,不同株行距生态因子变化有明显差异,并对小麦生长有一定影响。从实验区不同复合模式下小麦产量的高低考虑该区最佳的复合模式为:杨树间作行距≥30m,林网200m×300m。
Through the analysis of the eco-factor＇ s change rules during different phonological period in polar-wheat system in Xuhuai plain, it was found that in leaf-expansion period, ecological factors were nearly the same between different spacing in the rows, and it could satisfy the need of wheat. From omni leaf period to leaf-flourishing period, ecological factors of different spacing were obviously different. It could affect the wheat to some extent. The wheat output in different models of popular-crop was discussed and the best model were deduced.
