杭子梢以种子繁殖为主,虽然每株有成千上万朵花,但结实率并不高,尤其是生长在阴蔽条件下的植株,其结实率不到10%,杭子梢的实生苗第1 a生长极其缓慢,第2 a以后逐渐加快,一般在第3 a以后才能开花、结实。因此,2014年6月末-7月上旬,我们对杭子梢进行了嫩枝扦插实验。 Hangzhou shoots mainly seed multiplication, although each plant has tens of thousands of flowers, but the seed setting rate is not high, especially in the growth of shade plants, the seed setting rate of less than 10% The growth of seedlings in the first year was extremely slow, and gradually accelerated after the second year, generally after the third year, flowers and fruits were strong. Therefore, from the end of June 2014 to the beginning of July 2014, we carried out the shoot cutting experiment.
