Abstract
A method for breeding fast-growing poplar tree includes the first bud grafting between the twigs of southern-type poplar and northern-type poplar, the second bud grafting between same poplars, mutual grafting between their survival saplings, direct cuttaging, and grafting with the new saplings. Its advantages are high growth speed, high trunk, high wood quality, and high resistance to cold and drought.
Description
Technical field
The invention belongs to a kind of breeding method of new varieties of poplar, relate in particular to a kind of method that adopts the artificial cultivation grafting to cultivate the fast growth poplar new varieties.
Background technology
World today's protection environment; the deterioration of the ecological environment of preventing artificial destruction to cause; enforcement sustainable development strategy; become the problem of international community's economic development; when China implements the Midwest development strategy; also environmental protection; the ecology recovering environment; implement important topic and the object of planning of sustainable development strategy as the most important thing; and a series of corresponding preferential policies have been put into effect; encourage the central and west regions people in economic development, to do well to concede the land to forestry; prevent erosion, to reach the ecology recovering environment; anti-desertization; further enlarge the purpose of implementing sustainable development.In implementing the process of conceding the land to forestry, preventing to desertify, traditional plant variety has been introduced arbor kinds such as Sha Lanyang in recent years based on shrubs such as diversiform-leaved poplar, Semen Fructus Hippophae, but because these kind growths are slow, material is bad, resistance is poor, so concerning the peasant, economic benefit is not good enough.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art and a kind of breeding method that adopts Different Climatic Zones willow kind to hybridize the fast growth poplar of grafting is provided, utilize the good willow of Different Climatic Zones, purificate and rejuvenate, artificial spray breeds, make it keep fine quality, improve resistance to insects, resistance, growth is fast, and material obviously is better than the breeding method of the fast growth poplar of Sha Lanyang and the living poplar kind of other speed.
The object of the present invention is achieved like this: select for use the American-European black poplar of southern type for maternal, select this female parent for use annual bright, carry out the bud grafting first time with northern type Populus X canadensis cv., also select this female parent simultaneously for use annual bright, carry out the bud grafting second time with the American-European black poplar of northern type, the seedling of above-mentioned two kinds of bud grafting successes was adopted in the bud grafting success in back 1 year, carry out kryptoblast in July and exchange grafting, the 3rd year with the direct cuttage of two kinds of branches behind grafting survival plantation, carry out grafting once more with newly-generated Cheng Miao then and be combined into one, become the new varieties of cultivation after surviving.
The present invention is through diversification seed selection grafting repeatedly, new varieties of poplar after cultivating successfully, tall and straight tall and big, the cold-resistant drought resisting of natural variation strain, the characteristic that material is good had both been kept, have fast, the smooth no hollow advantage of skin of Sha Lanyang growth again, and American-European black poplar leaf is big, that speed is given birth to characteristics have embodied.
Main economic and technical indices:
1, speed is given birth to technical indicator: 15 months diameters of a cross-section of a tree trunk 1.3 meters above the ground " 12cm, leading thread " 15cm, vegetative period with diameter of a cross-section of a tree trunk 1.3 meters above the ground 30cm for becoming a useful person, high liquid manure area need 5 years, arid area 8 years, fast natural disposition is day third of the twelve Earthly Branches 1.6 times of poplar, is 8 times of Sha Lanyang;
2, material is good, is white in color, and fineness is good, and is pliable and tough strong, resistance to insects, strong stress resistance, and growth is fast, and material obviously is better than Sha Lanyang and the living poplar kind of other speed.
3, paste-forming properties is good can be good, and former pulp brightness height, thick slag are few, are the good materials of making high-grade paper and plywood.
Embodiment
Embodiment: select for use the American-European black poplar of southern type for maternal, select this female parent for use annual bright, with selecting northern type Populus X canadensis cv. for use is that annual bright of male parent carries out the bud grafting first time, also select this female parent simultaneously for use annual bright, again with carrying out the bud grafting second time as the American-European black poplar of the northern type of male parent, the seedling of above-mentioned two kinds of bud grafting successes was adopted in the bud grafting success in back 1 year, carry out kryptoblast in July and exchange grafting, the 3rd year with the direct cuttage of two kinds of branches behind grafting survival plantation, branch is put into water immersion 12 hours before the cuttage, then in 0.05% root element solution, can carry out the cuttage plantation, the 4th year, survive seedling with newly-generated two kinds and carry out grafting and be combined into one, become the new varieties of cultivation after surviving.Whole diversification cultivating process is pyramid, the new varieties of place, pinnacle of a pagoda for cultivating.
