摘要
为了缩短育苗周期,提高育苗成活率,培育合格的良种壮苗,连续四年在平罗县对臭椿(Ailanthus altissima(Mill.)Swingle)、白腊(Fraxinus chinensis Roxb.)、国槐(Sophora japonica Linn.)和新疆杨(Populus alba var.pyramidalis Bge.)进行覆膜育苗试验,获得明显的成效。试验结果证明,覆膜育苗与露地育苗相比,具有成苗率高,苗木生长健壮整齐,抽干程度轻,周期可缩短一年,经济效益十分明显等特点,具有很大的推广价值。
For shorten cultivation period, enhancing cultivation surviving rate, and cultivating good seedling ,We studed the mulching cultivation by setting seedling about forestation tree which were Ailanthus altisima, Farxinus chinensis, Sophora japonica and Populus alba var.pyramidalis in continous four years in Ningxia Pingluo where have the best technique condition, we getted abvious effect. The experiment showed that compared with land cultivation by setting seedlings, mulching cultivation by setting seedlings has many good characteristics , including higher surviving rate and formal seedling, which can reduce seedling period one year and economy benefit obvious , worth to adopted .
