Abstract
The invention discloses a method for grafting, cutting and fast propagating a Chinese white poplar twig, and relates to the field of woods elite breeding; and with the adoption of the method, the purpose of fast propagating Chinese white poplar own-rooted seedling is achieved. The method has the advantages that (1) maternal excellent characteristics can be maintained; (2) the seedlings are grafted in June to September every year; the sprout grafting survival rate is up to 95% above; seedlings produced in a cuttage pool with diameter of 10 meters are 10000 to 35000 plants; the survival rate of cuttage seedlings is up to 95% above; the survival rate of transplanted new seedlings is up to 90% above; the seedling from emergence to the end of Autumn in the same year is 0.5-1.5m high; the seedling growth amount in the second year is up to 4m above, which is 1.5-2 times higher than that of Paonian seedling that is a kind of poplar, so that the seedling culture year limit is shortened; (3) Yitiaobian (another kind of poplar) twig grafting and twig grafting body cuttage can be combined to be performed for multiple times in summer; the propagation coefficient is high; and the elite breeding speed is greatly improved; and (4) Taiqingyang (another kind of poplar) has the characteristics of easiness in rooting and easiness of twig in rooting; and the tow characteristics are fully utilized and combined to turn the Chinese white poplar new stem rooting from hard to be easy.
Description
Technical field
The present invention relates to forest stock breeding field, a kind of Chinese white poplar grafting of tender branch cuttage specifically is the method for breeding fast.
Background technology
Chinese white poplar (
Populus tomentosaCarr) be Salicaceae, Populus fallen leaves megaphanerophyte, growth is fast, and trunk is perfectly straight tall and straight, and tree-like grace is good afforestation seeds.Chinese white poplar originates in China, and it is wide to distribute, and is good afforestation seeds; Adaptability is strong, also is good shelter forest seeds; Chinese white poplar still is that important speed is given birth to commerical tree species and pulpwood raw material.
But the Chinese white poplar seedling-wood breeding is difficulty very, and the normal cutting propagation breeding is not taken root; The numerous restriction that is subjected to elite stand quantity again of root, and nursery stock is uneven of poor quality, how to solve its propagation technique, is bottleneck and key that the Chinese white poplar new lines is applied.In order to cultivate the Chinese white poplar own-rooted tree, big gun commonly used is twisted with the fingers grafting in the production, but speed is slow and need storage for the winter, and is time-consuming.
Summary of the invention
For solving the technical problem of above-mentioned existence, the invention provides the fast method of breeding of a kind of Chinese white poplar grafting of tender branch cuttage, reproduction speed is fast, survival rate is high, become the seedling time short, has effectively solved the Chinese white poplar difficult problem of growing seedlings.
For achieving the above object, the technical solution used in the present invention is as follows:
(1) grafting: utilize safe Cathay poplar give birth to then cuttage seeding or next year stump plant do stock, upwards carry out Chinese white poplar " fourth " font " whip " bud grafting every 5-10cm from ground 10cm, reach apart from taper 20-30cm and end, next year, stump plant can carry out in 6-9 month, and cuttage seeding can be carried out in the 7-9 month then;
(2) cut fringe: destroy the stock top tip after the grafting and promote to budder sprouting, relative stock bud on the plugged ear of erasing, removed the bondage thing in 10-20 days, treated that young sprout was long to 5-20cm in 10-30 days, take out the plugged ear that stock is cut into behind the living young leaves 5-10cm, upper cut is flat nick, and lower cut is angular cut, 1 of every fringe is buddered, and upper cut is from the 1-2cm that budders;
(3) cuttage: after the intercepting plugged ear, every fringe keeps 1 in stock blade, immediately unrooted graft oblique cutting is arrived full exposure intermittent spraying cuttage and seedling culture pond, matrix is the mixture of husky and vermiculite volume ratio 1:1, and with the sterilization of 1000 times of carbendazim, transplant the cm of seeding row spacing (5-10) cm * (5-10), the degree of depth is the new stem 2-3cm of matrix buried depth Chinese white poplar, in time start automatic sprayer, according to temperature, sunshine, situation arranged the spraying number of times, cloudy day or rainy day cut down according to the circumstance or stop-spraying, gradually reduce the spraying number of times after 10-20 days, close on to shift out the 3-7 days stop-sprayings in cuttage pond and change into watering and keep water supply in media;
(4) transplant: new stem-root seedling moved into the land for growing field crops in cuttage 20-60 days, and water permeablely for it, sheltered from heat or light 1-2 days, transplanting density 4500-7500 strain/hectare, Routine Management gets final product thereafter.
The present invention adopts grafting of tender branch in conjunction with the method for epicormic branch cuttage, has realized the purpose of fast breeding Chinese white poplar own-rooted tree, and its advantage is: 1. can keep maternal good characteristic; 2. the annual 6-9 month is carried out grafting, the survival rate of buddering reaches more than 95%, seedling 10000-35000 strain is produced in the cuttage pond that diameter is 10 meters, the cuttage seedling percent reaches more than 95%, transplant new stem shoot survival percent more than 90%, when year's harvest seedling to autumn Mo height of seedling 0.5-1.5 rice, the height of seedling amount of growth can reach more than 4 meters in 1 year, than the high 1.5-2 of big gun Nem seedling amount of growth doubly, shortened the time limit of growing seedlings; 3. a whip grafting of tender branch can repeatedly be carried out in conjunction with the cuttage of grafting of tender branch body summer, and reproduction coefficient is high, has improved stock breeding speed greatly; 4. taken full advantage of that safe Cathay poplar very easily takes root and the spray characteristics of taking root easily, the two combination makes the new stem-root of Chinese white poplar become very easily from difficulty.
