| 摘 要： | 通过对不同土壤类型及不同农作物茬口对日本落叶松育苗生长影响的试验研究,结果表明:在农茬地进行日本落叶松育苗应选择壤土或砂壤土,不宜选择碱土、砂土和黏土作苗圃地;不同茬口以日本落叶松重茬地育苗能够明显增加苗木生长量,以白菜茬为对照,日本落叶松重茬地可使苗高增加1.57倍,地径增加0.18倍,封顶量增加1.25倍,每hm2株数增加1.13倍。其他农茬首选大豆茬地、草木樨、瓜地茬,而谷子和白菜地茬不应作苗圃地繁育日本落叶松。

| Abstract: | Experiments of effect of different soil types and crop stubbles on seedling-raising of Larix kaempferi were conducted.The results showed that nursing of Larix kaempferi on stub land should select loam and sandy loam and shouldn't select alkali soil,sand and clay.Nursing with Larix kaempferi on restub land could increase the growth of seedlings significantly.Contrasting with cabbage stub land,the seedling height was increased 1.57 times by Larix kaempferi,ground diameter was increased 0.18 times,the crown increased 1.25 times.The number of stem increased 1.13 times per hectare.Soybean stub land,stub land of Melilotus suaveolens,melon field were preferred.The stub land of millet and cabbage should not be the nursery land to breed Larix kaempferi. |
