【Abstract】 Chinese golden larch survival rate is less than 30 per cent if common graftage is used. About 20000 seedlings were grafted by means of improved chip budding and veneer-scion grafting which was adopted during growing season with success. The average survival rate of graftling was 74 per cent, some excellent individuals above 90 per cent. Graftlings from 65 excellent individual trees were provided for the estabilishment of Chinese golden larch seed orchard, which has an area of 20 hectares.更多还原
