培育猕猴桃嫁接苗,目前多采用种子培育,实生苗作砧木,然后进行嫁接繁殖。根据我们多年来用种子培育实生苗的实践,能比常规提前一个月出苗,方法是: 一、猕猴桃种子沙藏 常规猕猴桃种子需经55～60天沙藏层积才有发芽率,从3月上旬种子播种到出苗还需25天。这样,种子从沙藏层积到出苗,共需90天左右时间。为使猕猴桃种子提前发芽、出苗,延长幼苗生长期,加粗根茎围度,达到理想的嫁接标准,我们采用缩短种子沙藏层积时间,改为种子变温处理,取得良好的效果。把已沙藏层积20天左右的种子取出,放进 Cultivation of kiwi grafted seedlings, the current use of more seed cultivation, seedlings for rootstock, and then graft breeding. According to our practice of seedling seedlings over the years, the seedlings can be germinated one month earlier than conventional methods. First, the conventional kiwifruit seeds in the sandy seed bank of kiwifruit need to have germination rate after 55 to 60 days of sediment storage in the sand layer. From March Early seed sowing to seedlings need 25 days. In this way, the seeds from the sand reservoir to the emergence of seedlings, a total of 90 days or so. In order to make the seeds of kiwifruit germinate in advance, sprout, extend the seedling growth period, thicken the rhizome circumference, and achieve the ideal grafting standard, we adopted the shortened stratum sediment stratification time, and changed the seeds to the temperature change treatment, and achieved good results. Take sand that has been deposited for about 20 days and put it in
