| 摘 要： | 通过对落叶松水曲柳混交林中根际土壤交换性阳离子的比较,得到了落叶松水曲柳混交林根际土壤交换性阳离子的变化趋势为:除钠外,落叶松的各项交换性阳离子含量均大于水曲柳,钠与钾、钙、镁存在拮抗作用,营造落叶松混交林有利于促进落叶松的生长。

| Abstract: | Comparing the rhizosphere soil of mixed forest of larch and ash, variable trends of exchangeable cation in the rhizosphere soil of mixed forest of larch and ash were obtained. Except the sodium, exchangeable cation content of larch is more than that of ash. Sodium acts antagonistically with potassium, calcium and magnesium. Mixed forest silviculture can accelerate the larch growth. |
