1990年春,我们采用温室催芽、春季播种和地膜育苗一整套技术措施,培育柚实生砧木苗的试验,并取得初步成功。试材为本地10年生以上实生酸柚树的成熟鲜果,预贮3天后,用3%小苏打溶液浸种,晾干贮藏。翌春,堆腐取种,淘洗晾干后,选取饱满、形正、新鲜的种子备用。其方法如下:播种前用35—40℃温水浸种1小时,再加入0.4%高锰酸 In the spring of 1990, we adopted a series of technical measures such as greenhouse germination, planting in spring and plastic seedling nurturing to cultivate the rootstock seedlings of pomelo and achieved initial success. The test material is the fresh fruit of the local pomelo tree, which is over 10 years old. Pre-stored for 3 days, soaked with 3% sodium bicarbonate solution and dried to store. The next spring, heap seized, washed to dry, select full, shaped, fresh seeds spare. The method is as follows: before sowing with 35-40 ℃ warm water for 1 hour, then add 0.4% permanganic acid
