我们于一九七六年开始在大通县下丰积大队、鲍二大队和西宁市湟水林场进行了油松营养钵塑料薄膜大棚育苗试验。试验说明利用塑料薄膜大棚育苗不仅能促进苗木快速生长,缩短育苗周期,而且还是培育壮苗、提高造林质量的有效途径。塑料薄膜大棚培育的苗木,一般茎生长比露地同令苗高1—2倍;根径生长大王倍左右。

In 1976, we started the seedling nursery trials in the plastic film greenhouse of Pinus tabulaeformis in Xia Feng plot brigade, Bao Er Brigade in Datong County and Xishui Guishui Forest Farm. The experiment shows that the use of plastic film greenhouse nursery can not only promote the rapid growth of seedlings, shorten the nursery cycle, but also to cultivate strong seedlings and improve the quality of afforestation an effective way. Plastic film nursery nursery stock, the general growth of stems than the open field with the seedlings 1-2 times higher;
