常规育苗的种子处理方法是冬季沙藏法。即冬天将种子和沙按1:4的比例混合均匀埋在沟内进行沙藏,翌年春天待种子发芽时再进行播种。但你有些海棠籽未来得及沙藏,也可用快速催芽法进行处理。 Conventional seedling treatment is the winter sand storage method. In winter, seeds and sand are mixed in a ratio of 1: 4 and buried in a trench for sand storage. In the spring of next year, the seeds are sown for further planting. However, some Begonia seeds can not reach the sand reservoir in the future, but they can also be treated by rapid germination.
