Abstract
The invention discloses a method for shortening building time of a garden of Masson's pine clone graft seeds. According to the characteristic that slash pine is superior to Masson's pine in early growth, stocks of slash pine and Masson's pine are planted in a manner of two plantlets in one hole, and slash pine is grafted to Masson's pine in autumn and is supplementarily grafted in spring. Therefore, garden building time is shortened effectively while guaranteeing building quality, and the building efficiency of the Masson's pine clone graft seed garden is improved. The seed garden can be built for only 14 months by the method, which is 8 months smaller than the traditional building time. The efficient building method is economical, efficient, simple to operate, applicable to construction of bases for fine Masson's breeds and popularization to base production institutions, and practically significant to building of fine bases for Masson's pine.
Description
Technical field
The present invention relates to masson pine seed garden Jian Yuan, especially a kind of shortening masson pine clone grafting seed orchard is built the garden time method.
Background technology
Masson pine (Pinus massoniana) is China important dual-purpose seeds of fat material in south, and it is of many uses, economic worth is high, is the primary raw material seeds of industries such as China woods slurry paper (plate), rosin and building.Except that timber and two large purposes of rosin, the full tree of masson pine is all capable of using, and pollen, needle and bark are rich in polyphenoils, can be used as good anti-ageing and anti-oxidation health article; Pine nut oil-containing 30% can be made paint, soap and lubricating oil; Cone can refine crude oil; Pine stump can extract pine tar, can also cultivate precious traditional Chinese medicine---Poria cocos.
Through the genetic improvement research in more than 30 years, masson pine fine provenance-superior stand-seed collecting seed production stand-primary seed garden-improvement was built up for multi-level breeding bases such as seed orchards in Guangxi, was promoting to have brought into play important function aspect the masson pine improved variety process.During primary seed garden to " 12 " of the enforcement period of the seventh five-year plan the 2nd generation seed orchard, nearly ten thousand mu in all kinds of masson pine seed garden of different cultivation targets has been built in Guangxi, has summed up the garden of the building technology of a cover masson pine clone grafting seed orchard perfect.But in the construction process of seed orchard, be cultured to seed orchard from stock and build up, generally need 1.5～3 years, build long, the low conspicuous contradiction that becomes many masson pine breedings production base of economic benefit of garden time.Therefore, how to shorten that to build the garden time be the major issue that each production unit needs to be resolved hurrily.
In the South China, the Best Times of masson pine grafting is 10～November of autumn, this period graft survival rate high (more than 95%), and scion becomes to live and can take out the tip growth back to spring next year; Second section comparatively ideal grafting time is 3～April, and this moment, spring temperature went up, and grafting interface healing time is short, before summer high temperature, takes out tip growth if grafting survival still can be caught up with, but takes out tip height and growing way all is slightly poorer than the grafting in autumn.The grafting method in autumn of wet-land pine tree stock is adopted in the construction of masson pine clone grafting seed orchard in the past more, yet the grafting in autumn is not if become alive, and owing to the growth of wet-land pine tree leading thread is very fast, the leading thread of wet-land pine tree was excessive when benefit connect to spring, often suitable subsides ground grafting.
Summary of the invention
The technical problem that the present invention will solve provides a kind ofly operates shortening masson pine clone grafting seed orchard simple and easy, economical and efficient and builds the garden time method, builds the garden time with effective shortening, improves the construction efficient of masson pine clone grafting seed orchard.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: shorten masson pine clone grafting seed orchard and build the garden time method, may further comprise the steps:
< 1>decide anvil 3-4 month, adopt the two strains in a cave decide anvil, in each cave the while field planting 1 strain wet-land pine tree and 1 strain masson pine;
Grafting near the ground when < 2>the wet-land pine tree stock leading thread of grafting to step < 1>reaches 0.6～1.5cm;
< 3>connect back management and the scion of step < 2>grafting survival is separated tie up and cut anvil, do not become wet-land pine tree stock alive to remove;
< 4>benefit connects next year 3-4 month, makes the stock benefit with masson pine and connects repeating step < 3 >.
The wet-land pine tree and the masson pine of deciding anvil in the step < 1>are eugonic 1 year living strong sprout of no damage by disease and insect.
The present invention utilizes wet-land pine tree to have the advantages that early growth is superior to masson pine; Anvil is decided in the two strains of wet-land pine tree and masson pine one cave; Adopt wet-land pine tree grafting in autumn masson pine benefit in spring to connect mode; Build under the prerequisite of garden quality in assurance, effectively shortened and built the garden time, improved the construction efficient of masson pine clone grafting seed orchard.Use the present invention and build seed orchard, only need 14 months, build the garden time than tradition and shorten 8 months at least.Owing to shortened and built the garden time, make in the seed orchard the different clonal ages more consistent with growing way, be convenient to the tending management of seed orchard and the management and utilization of pollen.Efficient garden building method economical and efficient of the present invention and operate simple and easyly is suitable for the construction of base of masson pine breeding and basic unit's production unit is applied, and the breeding construction of base of masson pine is had important realistic meaning.
