春季播种的果树种子,都要经过层积处理才能发芽,目前生产中大多采用细砂层积处理。细砂虽然经济方便,但处理种子较多时,播种前搬运不方便,芽容易受到砂粒创伤,种子出苗率不高,出苗不整齐。为此,经过多年育苗实践,选用新鲜锯沫做层积材料,用高锰酸钾溶液浸泡种子和消毒锯沫,准确掌握层积方式,取得较好的效果。具体的法如下: 一、锯沫的选择:选干燥、新鲜、不含土和其它杂物的锯沫,一般木器厂锯沫应筛除土块等杂物。发霉、陈旧的锯沫不宜选用。
Spring sown seeds of fruit trees, have to go through stratification to germinate, most of the current production of fine sand stratification. Fine sand, though economical and convenient, can not be easily transported before sowing due to the large number of seeds. The buds are easily traumatized by sand grains. The germination rate of the seeds is not high and the seedlings are irregular. To this end, after years of nursery practice, the selection of fresh sawdust laminated materials, potassium permanganate solution soaking seeds and disinfectant saw foam, accurate grasp of the stratification, and achieved good results. The specific method is as follows: First, the choice of sawdust: Select dry, fresh, do not contain dirt and other debris saw the foam, the general wood plant sawdust should remove clods and other debris. Moldy, old sawdust should not be used.
