泡桐旱地埋根育苗,除应选择沙质壤土及加强锄草松土、病虫防治外,还应从以下几个方面注意: 一、施足底肥旱地泡桐埋根育苗,一般需经过两年培育才能出圃。第一年苗木生长情况如何,直接影响次年培育健壮苗木。育苗前施足底肥(20000斤/亩),苗子当年形成庞大根系,就为培育健壮苗木打好了基础。如果底肥不足,依靠追肥来保证苗木需要,不但费工,同时,还常因5—6月份缺雨,影响及时追肥,而错过泡桐生长迅速期。只有饱施底肥,结合追肥,才能培育出泡桐壮苗。
Paulownia dry land nursery seedlings, in addition to the selection of sandy loam and strengthen weeding loosening, pest control, should also be noted from the following aspects: First, the application of fertilizer at the end of the ground Paulownia nursery seedlings, the general need to cultivate after two years to Out garden. The first year how the growth of seedlings, directly affect the cultivation of robust seedlings the following year. Pre-nursery facilities at the end of fertilizer (20000 kg / mu), the formation of large seedling roots, to lay a solid foundation for the cultivation of robust nursery stock. If the lack of base fertilizer, relying on top-dressing to ensure seedling needs, not only work, but also often due to lack of rain in May-June, affect the timely top dressing, but missed Paulownia growing rapidly. Only full base fertilizer, combined with top dressing, to cultivate strong Paulownia seedlings.
