沙棘资源的开发利用,已经引起人们的重视。但是在现有的资源中,无论是天然林还是用实生苗营造的人工林,都存在着雌雄株比例失调、产量低的问题。通过嫁接育苗的方法,既可以克服播种育苗遗传变异较大的弱点,又能避免扦插育苗不易生根成活的缺陷,定向培育出品质优良的雌雄株苗木,营造沙棘园,提高沙棘果单位面积产量,达到发挥其最大经济效益的目的。现将沙棘嫁接育苗的方法介绍如下。一、砧木的选择。选用一年生根系发达、生长发育健壮、无病虫害的沙棘实生苗做砧木,地际径要求在0.6厘米以上二、接穗的采集和贮藏
Seabuckthorn resources development and utilization, has drawn people’s attention. However, existing resources, whether natural forests or planted with artificial plantations, there is a problem of imbalance between male and female plants and low yields. The method of grafting seedling can not only overcome the shortcomings of large genetic variation of sowing nursery seedlings, but also avoid the defects that rootstock seedling is not easy to survive. Directional breeding of male and female seedlings of good quality, creating seabuckthorn garden, increasing yield per unit area of seabuckthorn fruit, To achieve its maximum economic efficiency purposes. Now seabuckthorn seedling grafting methods are described below. First, the choice of rootstock. Selection of annual root system developed, robust growth and development, no pests and diseases of seabuckthorn seedlings do rootstock, ground diameter requirements in 0.6 cm above the second, scion collection and storage
