Embodiment Construction

[0010] Embodiment: select the five-year-old Shennongjia area of ​​Hubei Province, the trunk is straight, the crown diameter is more than 4 meters, no flying catkins, falling ears, tree height more than 30 meters, and the natural hybrid wild poplar and Qing Yang of more than 38 centimeters diameter. The mutated tree species is the female parent, and the annual Mingtiao of the female parent is selected, and the northern type Populus saranii is selected as the male parent for the first bud grafting. Carry out the second bud grafting. In the second year after the bud grafting is successful, use the above two seedlings with successful bud grafting. In July, carry out the grafting of hidden buds. In the third year, use the two kinds of branches that survived the grafting for direct cutting planting. The branches before cutting Soak in water for 12 hours, and then plant cuttings in 0.05% rooting factor solution. In the fourth year, use two newly generated surviving seedlings to graft ...

Abstract

A method for selectively breeding fast-growing poplar includes the first bud grafting between wild white poplar and northern-type poplar, the second bud grafting between same poplars, mutually grafting between their survival saplings, direct cuttaging, and grafting with the new saplings. Its advantages are high growth speed, high trank, high wood quality, and high resistance to cold and drought.

Description

technical field [0001] The invention belongs to a method for breeding new varieties of poplars, in particular to a method for cultivating new varieties of fast-growing poplars by adopting an artificial multiple cultivation method. Background technique [0002] In today's world, protecting the environment, stopping the deterioration of the ecological environment caused by man-made destruction, and implementing sustainable development strategies have become the subject of international social and economic development. The sustainable development strategy is an important topic and planning goal of the top priority, and a series of corresponding preferential policies have been introduced to encourage people in the central and western regions to do a good job in returning farmland to forests while economic development, to prevent soil erosion, and to restore ecology environment, anti-desertification, and further expansion of the implementation of sustainable ...
