通过对胡桃楸进行秋季覆膜播种育苗试验研究，结果表明，胡桃楸秋季覆膜较无覆膜对照提高出苗率21.6%，苗高提高12.4%，地径提高15.1%，侧根长提高11.6%，主根长提高6.8%；覆膜较对照提前7 d 出苗，每667 m2平均育苗株数达1.3万株。秋季覆膜提高了土壤的昼夜温差，保持土壤湿度，促进了胡桃楸种子的炸口率，提高了出苗率和生长量。
通過對鬍桃楸進行鞦季覆膜播種育苗試驗研究，結果錶明，鬍桃楸鞦季覆膜較無覆膜對照提高齣苗率21.6%，苗高提高12.4%，地徑提高15.1%，側根長提高11.6%，主根長提高6.8%；覆膜較對照提前7 d 齣苗，每667 m2平均育苗株數達1.3萬株。鞦季覆膜提高瞭土壤的晝夜溫差，保持土壤濕度，促進瞭鬍桃楸種子的炸口率，提高瞭齣苗率和生長量。

Experiments of sowing with film mulching and seedling-raising for Juglans mandshurica were conduc-ted.Result shows that:the emergence rate,the seedling height,the ground diameter,the lateral length,the main root length of Juglansmandshurica with film mulching in autumn is 21.6%,12.4%,15.1%,11.6% & 6.8%respectively higher than that of Juglans mandshurica without film.The seedlings of Juglans mandshurica with film mulching emerge seven days in advance than that of CK.The average seedling number reach 13 000 trees per 667 m2 .Juglans mandshurica with film mulching in the autumn increase the differences of day-and-night temperature, preserve the soil moisture,promote the seed crack rate of Juglans mandshurica,increase the emergence rate and growth.
