摘要
核桃种子休眠期较长,春季播种时必须用水浸种,由于当地气温较高、湿度较大,种子极易发芽、出虫和霉烂。该技术无需贮藏、催芽和规模耕地,只需修复好畦埂,便于灌溉;种子采集后及时进行熏蒸、播种,利用灌溉保持土壤湿润,以防止鼠危害。免除了整地、贮藏等常规措施,相对降低了育苗成本,出苗率达90%以上。
Seed of walnut has a long dormant period and will be soaked before sowing,which in turn would cause decay or become mildew or insect damaged.This technique does not need storage and only needs ridge preparation.Seeds after harvesting need to be steamed and then sowed,which prevent them from being damaged by hare and mouse and exempted from site preparation and storage,making the cost lowered and germination rate above 90%.
