俄罗斯杨(P.Russkii Jabl.)夏季扦插造林技术研究初报

Primary Report on Summer Cuttage Forestation Technique of P. Russkii Jabl.

大面积扦插造林在我国研究实用较少,美国在营造杨树纸浆工业原材料上,研究应用非常广泛,而夏季大面积扦插造林国内外未见报道。在克拉玛依"林纸一体化"项目上,短期内为了栽植6.67×104hm2(100万亩)纸浆工业原料林,新疆林科院开展了在特殊地区(风大、风多、干旱)全年造林技术研究与示范:2000年秋季造林66.67hm2,2001年春季造林800hm2,5月下旬至7月上旬用营养钵造林1333hm2,在6～8月用俄罗斯杨扦插造林368.7hm2,在土壤和灌溉条件较好的情况下,扦插造林成活率达73%～90%,效果很好,造林成本低、速度快,具有广泛的推广应用前景。

The great area of summer cuttage forestation is quite less studied in our country. The technique of construction pulp industry with original wood of poplar trees is very extensively applied in the United States. But the technique about great area of summer cuttage forestation has never been reported in China. In order to plant one million acre of pulp industry raw material wood for a short time, the technique of cuttage forestation all the year round in the special area ( area with strong wind, frequent wind and arid climate ) was studied and demonstrated by Xinjiang Academy of forestry Sciences. In 2000 autumn the cuttage forestation area reached 66.67 hectares. In 2001 spring the cuttage forestation area reached 800 hectares. From the last ten-day period of May to the first ten-day period of July it reached 1 333 hm^2. From June to August, the area of cuttage forestation of P. Russkii Jabl. reached 368.7 hm^2. Under the better conditions of soil and irrigation, the survival percentage of cuttage forestation reached 73%～90%. So the cuttage forestation has opened vast vistas for the development of forest in our country.
