分析了八种树苗浸出液对其它五种苗木成活生长的影响。结果表明，胡桃楸树苗浸出液对其被浸根苗木的颉抗（毒害）作用是有选择的，它使红松、红皮云杉、樟子松被浸根苗木当年成活率和当年高生长大幅度降低．并使兴安落叶松苗木全部死亡．但对水曲柳苗木影响却不大。水曲柳、大青杨树苗浸出液会引起被浸根兴安落叶松苗木当年成活率和高生长的降低，而兴安落叶松树苗浸出液浸水曲柳苗根对被浸苗木当年高生长则无影响。红松、红皮云杉、兴安落叶松、水曲柳、白桦等五种树种苗木浸出液分别浸樟子松苗根对提高樟子松当年高生长量效果较显著。
The effects of eight sap leachate on the survival of five other seedlings were analyzed. The results showed that the extract of Juglans mandshurica saplings was selective for its antagonistic (poisonous) effect on the seedlings being dipped in roots. The survival rate of the seedlings of Pinus koraiensis, Picea koraiensis and Pinus sylvestris var. The rate of decrease. And Larix seedlings all died. However, the impact of seedlings of ash is not large. Ash, poplar sap leachate will cause the rooted Larix gmelinii seedling survival rate and high growth decreased, while the Larix gmelinii seedling leaching solution of soaking seedlings of soaked seedlings then high growth has no effect. The results showed that Pinus sylvestris var. Mongolica and Pinus sylvestris var. Mongolica were significantly effective in increasing Pinus sylvestris var.
