Our country was established in January 1958 and has a land area of more than 6,000 mu, all of which are located in the southern bank of the old course of the Yellow River. Last year, we cultivated 16 acres of Begonia rootstock. According to check before deciduous fruit: Rootstock seedlings height 100-132 cm accounted for 20%, 85-100 cm accounted for 60%, 70-85 cm accounted for 20%, cadres, the most coarse 6 cm, the general is 3.5 Cm. In the same year, 82,000 buds were sprouted and the sprouting rate was over 65%. The survival rate was 89%. Some sprouts germinated in the same year, up to 40cm in length. If it can be cut in time, it is estimated to reach a height of 80cm or more. Our whole nursery process and measures are as follows:
