The golden tree is a deciduous tree, its leaves from leaf expansion to fallen leaves are golden yellow, to the late autumn to early winter, leaves fall, whole tree branches because of the frost wind, also from light yellow to become deep yellow, is golden.
A, cutting propagation, in October after the new leaves, branches cut growth strong, cut into 15 cm pieces, the bundle into the water soak 30 hours, let it absorb enough moisture. Then the strong rooting agent with water to 100 times the concentration dilution, coupled with the clay paste, smear stained with cuttings root cuttings, immediately to the greenhouse seedling sand bed, maintained at a temperature of 30 DEG C, humidity around 80%. So the roots emerged shoots, timely transplanting to the greenhouse, plant and row spacing of 15 x 25 centimeters advisable. Seedlings of Qi 10 centimeters when pouring a little water, spraying of foliar fertilizer, promote seedling growth. When the outside world average temperature at 20 degrees, the greenhouse film gradually uncover (avoid by all means is a take off membrane, to prevent exposure seedling), reusable shade net shade in one to two weeks, to prevent the death of seedlings.
Two, grafting. With the biennial ordinary Sophora rootstock, outdoor intercepted before Qingming long with 4 to 5 buds golden Sophora twig segments were grafting law breed, fertile rootstock seedlings in the greenhouse, were budding breeding in June of that year, this year can breed finished seedlings. Specific methods: the Sophora japonica seed dormancy first low temperature treatment, the seed and sand (80% humidity) mixing well, put back the shade of desertification, dormancy, temperature at around 0 degrees, not to the East into a lump of ice is appropriate. Fifty days can be a hotbed of germination, until the forty percent small white bud, can mounding in greenhouse planting. In mid June, when the small seedling base minister to 0.5 cm when grafting. This is mainly the budding, with wooden double tongue butt. Method is: use the knife in the rootstock base downward beveled knife, then from the 2.5 cm incision under the cut depth up to 2 mm, xylem, become a tongue groove. Then from the scion with the same methods of operation cut tongue bud of the same size in ligulate slot (scion and rootstock thick must match, not the gap is too large, so as not to cause the cortex cannot agree, lower survival rate), with plastic film tight, then from the bud to stay 3 to 4 leaves, cut off excess, promote nutrient return as soon as possible, make bud healing survival.
