沙地植物柄扁桃的生物学特性及引种栽培的研究

通过研究发现柄扁桃具有典型旱生植物的形态结构特征。同时，在生理特征上也与旱生环境相适应。因此，在沙区引种栽培柄扁桃是可行的。柄扁桃的繁殖主要采用播种法，利用沙藏催芽法处理种子，树苗当年可出圃造林。沙地造林采用植前造林法，将株高４０—１００ｃｍ的健壮苗在春季栽植于平缓的沙地、沙丘迎风坡下部或丘间地等风蚀轻、水分条件好的沙地。

THE BIOLOGICAL CHARACTERISTICS AND INTRODUCTION AND DOMESTICATION OF PRUNUS PEDUNCULATA

Prunus pedunculata has the morphological and structral features of typical xerophyte,at the same time,its physiological feature is adaptation to arid habitats.Therefore,it is feasible that Prunus pedunculata is introduced in sandy desert.Pranus pedunculata is propagated mainly by sowing seeds,seeds are treated with stratification forcinggermination,seedlings are transplanted to sandy lands for afforestation the same year.But it is important that heathly and strong seedlings with 40-100cm height are chosedand cultivated in sandy lands with slight wind and good moisture condition such as gently sand lands,base parts of foredune or lands between dunes.
