胡杨移栽苗生长发育规律及栽培技术的研究

STUDIES ON THE RULE OF GROWTH AND DELELOPMENT AND CULTYATED TECHNIOUE FOR REPLANTING NURSERY STOCK OF POPULUSCUPHRATI蠥 OLIVER

胡杨优点虽多,但育苗困难,且生育缓慢,易染锈病。为适应宁夏胡杨大面积造林对苗木的需求,在川区通过胡杨移苗生长发育规律及栽培技术的研究,提出了以调苗栽植取代调种播种育苗的办法,其移栽苗在质量、育苗周期和经济效益方面,均优于当地播种育苗,摸索出了胡杨育苗的一条新途径。

Populus cuphratica Oliver has many advantages, but to breedthe young trees is very dificult, its growth and development is very slowly, it is frequently infected rust disease. In order to satisfy the need of nursery stock for afforesting the forest of Populus cuphratica in Ningxia, throughthe studies on rule of growth and development and cultivated technique for replanting nursery stock of Populus cuphratica, we put forward ,that a me-asure to adopt planting allocate and transporting the nursery stock alloca-tion replaces the measure of allocation and iransporting the seed for planting and breeding the nursery stock.The nursery stock is better than that is planting in local area in the quality of the stock, th;e period of breeding stock and the economical benifit, The new way for breeding the stock of Populus cuphratica is groped.
