Description
technical field:
The present invention relates to a kind of method of setting up cutting orchard large-scale breeding U.S. Chinese larch nursery stock, belong to
Forestry and green plant planting technique field, flower garden.
background technology:
U.S. Chinese larch originates in the pacific California of the U.S. and Oregon, is the most long-lived in the world, tall trees wood, and evergreen, growth is fast, and material is good, is good tree and the commerical tree species of viewing and admiring, and has been introduced a fine variety many countries in the world.U.S. Chinese larch is excellent at coastal area of china and the growth of the Changjiang river areas to the south, and its sight, growth rate and wood quality far exceed the most important commerical tree species China fir of south China.So we need amount reproduction U.S. Chinese larch.
The method of breeding U.S. Chinese larch has multiple.In the U.S., Chinese larch mainly adopts seminal propagation.Because American Red Chinese fir is very large, trunk diameter reaches several meters, and the height of tree is all at tens of meters, even more than 100 meters, seed is very little, easily disperses, and seed rests on high aerial dense branches and leaves, do not fall, so the difficulty of seed collecting, seed is very expensive, nearly 20,000 yuans of per kilogram, and germination rate is very low, 5% left and right of being everlasting.Seedling easily suffers from damping off, carry out soil disinfection or grow seedlings with aseptic soil moved in to improve the original, otherwise that nursery stock can be caused is large stretch of dead; Cover grass, take the work such as cloudy canopy, cost is high.So seeding and seedling raising is difficult to obtain the nursery stock of a large amount of low price.
In felling area, U.S. Chinese larch also has and adopts butt coppice shoot cottage propagation, or takes off wooden unit from stump, is placed in the dish being filled with water, and after growing the tender tip on wooden unit, is cut cottage propagation.Because material is few, this method irreproducible go out a large amount of nursery stocks.China does not have this condition yet.
President Nixon in 1972 is given Chinese Chinese larch seedling and is only had a strain.Hangzhou Botanical Garden adopts cuttage to breed thousands of seedlings and is distributed to botanical garden, various places and plants experimentally.Cuttage survival rate is along with the age of elite stand increases and reduces.The branch cutting survival rate of cutting from large tree is low, and trunk is crooked, hat partially, and growth is slow.In addition the branch that is suitable for Zuo Cha Miho that can adopt from a strain tree, is limited.The large tree of the existing Chinese larch of China is little.These are all the reasons that is difficult at present carry out on a large scale cottage propagation.
In order to overcome the shortcoming of cuttage, abroad, in some seeds, for example pine, has and sets up arbuscle cutting orchard and take branch cutting.Arbuscle cutting orchard can obtain more cuttings, adopts bar convenient, has also shortened the distance between cuttings and root system, has improved cuttage root-taking rate, than not building cutting orchard advanced person.But the cuttings of arbuscle cutting orchard or far from root, less than the rootability of butt coppice shoot.The more important thing is, along with the growth of the age of tree, the power of taking root still will reduce, and must rebuild one time cutting orchard after the several years.In U.S. Chinese larch, yet there are no the report of building arbuscle cutting orchard.
According to another report, there are a company annual 1000000 strain Chinese larch seedlings of cultivating of group training method in the U.S. for greening.In recent years, China also had people's employing group training method to grow seedlings, and had built the Chinese larch woods of 50 mu of a slices with group training seedling.U.S.'s Chinese larch veteran cuttage survival rate is low, but in group training process after subculture is cultivated several times, through hormone adjustment, newborn budling has had the same rootability of seedling, so group training method has the ability that makes veteran rejuvenation.But the shortcoming of its maximum is to build special group training chamber, to carry out strict sterilization, sterilizing to examination material and apparatus, subculture is cultivated, culture of rootage all will be carried out strict sterile working, also have seedling to go out to plant, practice many steps such as seedling, technical sophistication, must be operated by special technical staff, and common peasant is not competent, therefore, the cost of group training method is high.In addition, due to its complexity, be unsuitable for cultivating with a lot of individualities, this nursery stock hereditary basis that it is brought out is very narrow, and lack of diversity is unfavorable for the annidation of following standing forest and the repellence to sick worm.
summary of the invention:
Set up a method for cutting orchard large-scale breeding U.S. Chinese larch nursery stock, key technology of the present invention is to build a special coppice shoot cutting orchard for the slotting Miho of collection.Coppice shoot cutting orchard builds up by the following method: 1, utilize existing Chinese larch to grow up and set greatly: the 4-6 month is taken off diameter 2-5cm from the large tree that grows up, be subject to the sufficient healthy and strong branch of light, branch is cut into the brachyplast of 40-60cm, leave a healthy and strong sprig and remaining is removed, separately get the metasequoia seedling of life in to two year, cut root system, the root system of grafting 2-3 metasequoia seedling on Mei Gen U.S. Chinese larch brachyplast, ties up with numb skin; Grafting metasequoia root system is in order to guarantee that Chinese larch brachyplast survives and grow coppice shoot and own root system, if branch is larger, also can grafting, and the nutrient of branch self is enough to guarantee the root system that grows coppice shoot and control oneself.The brachyplast that is connected to root system is laterally imbedded in nursery, and dark 20-30cm, allows the sprig retaining basset.The sprig basseting can be used as mark, and can continued growth become tree crown, carries out photosynthesis, for plant provides nutrition.Be embedded in underground brachyplast and can grow many coppice shoots, coppice shoot base portion can grow root system, in the time that coppice shoot grows to certain altitude, it is cut off with reaping hook from subsurface.Because Chinese larch has sprouts of stump ability, after a tender tip cuts off, can from otch, grow the more new tender tip, therefore constantly cut off the tender tip, constantly coppice shoot, constantly grows root system, so repeatedly operate after two to three times, just can grow the close coppice shoot of a slice height cardinal principle.
2, utilize tree seedling: tree seedling raw 1-2, by certain seeding row spacing field planting, at a side trench digging for nursery stock, is done to horizontal burying in soil by seedling after surviving, and the continued growth of basseting of the seedling tip, makes it grow up to a strain little tree and carry out photosynthesis.Along with the seedling tip continue grow tall, the horizontal tender tip making new advances the underground president of stem.The tender tip has a lot of bars, and the base portion of the tender tip can grow root system, finally grows the coppice shoot that many height equate substantially.The height of coppice shoot can be controlled by the time of cutting.In the time that coppice shoot grows to certain height, available reaping hook extracts for cuttage from subsurface.Under suitable weather conditions, within 1 year, can carry out cuttage and seedling culture two to three times, greatly increase the seedling amount of producing.
Beneficial effect of the present invention: coppice shoot cutting orchard can be adopted bar for 1 year two, three times, product bar amount is high.Coppice shoot cutting orchard has the function of rejuvenation, and tloig-cutlage survival rate is high, and its effect is suitable with group training method, but it does not build group training chamber, do not adopt sterilization, sterilizing, subculture to cultivate, go out to plant, practice many steps such as seedling, method is simple, common peasant can operate, and cost is cheaper.In addition, cutting orchard is made up of a lot of individualities, and offspring's hereditary basis has diversity, and this is conducive to following standing forest and adapts to different environment and the repellence to sick worm.

For ease of explanation, the present invention is described in detail by following concrete enforcement and accompanying drawing.
Fig. 1 is the flow chart of the first cutting orchard large-scale breeding of the present invention U.S. Chinese larch nursery stock;
Fig. 2 is the flow chart of the second cutting orchard large-scale breeding U.S. Chinese larch nursery stock in the present invention.
embodiment:
As shown in Figure 1-2, specific implementation method of the present invention is: 1, utilize existing Chinese larch to grow up and set greatly: the 4-6 month is taken off diameter 2-5cm from the large tree that grows up, be subject to the sufficient healthy and strong branch of light, branch is cut into the brachyplast of 40-60cm, leave a healthy and strong sprig and remaining is removed, separately getting the metasequoia seedling of life in to two year, cutting root system, the root system of grafting 2-3 metasequoia seedling on Mei Gen U.S. Chinese larch brachyplast, ties up with numb skin; Grafting metasequoia root system is in order to guarantee that Chinese larch brachyplast survives and grow coppice shoot and own root system, if branch is larger, also can grafting, and the nutrient of branch self is enough to guarantee the root system that grows coppice shoot and control oneself.The brachyplast that is connected to root system is laterally imbedded in nursery, and dark 20-30cm, allows the sprig retaining basset.The sprig basseting can be used as mark, and can continued growth become tree crown, carries out photosynthesis, for plant provides nutrition.Be embedded in underground brachyplast and can grow many coppice shoots, coppice shoot base portion can grow root system, in the time that coppice shoot grows to certain altitude, it is cut off with reaping hook from subsurface.Because Chinese larch has sprouts of stump ability, after a tender tip cuts off, can from otch, grow the more new tender tip, therefore constantly cut off the tender tip, constantly coppice shoot, constantly grows root system, so repeatedly operate after two to three times, just can grow the close coppice shoot of a slice height cardinal principle.
2, utilize tree seedling: tree seedling raw 1-2, by certain seeding row spacing field planting, at a side trench digging for nursery stock, is done to horizontal burying in soil by seedling after surviving, and the continued growth of basseting of the seedling tip, makes it grow up to a strain little tree and carry out photosynthesis.Along with the seedling tip continue grow tall, the horizontal tender tip making new advances the underground president of stem.The tender tip has a lot of bars, and the base portion of the tender tip can grow root system, finally grows the coppice shoot that many height equate substantially.The height of coppice shoot can be controlled by the time of cutting.In the time that coppice shoot grows to certain height, available reaping hook extracts for cuttage from subsurface.Under suitable weather conditions, within 1 year, can carry out cuttage and seedling culture two to three times, greatly increase the seedling amount of producing.
The theoretical foundation of this embodiment is: on physiology, tree root is childhood, the most easily take root from the branch that root system is nearest, so butt coppice shoot or the easiest cutting survival of Stump plant, branch from root system away from more, due to the difference of growth hormone, moisture, nutrient transport, on physiology, become aging, cuttage is more difficult takes root.This embodiment said " coppice shoot that a slice height cardinal principle is close ", the real hurst that has root for approximately 10 centimeters of a slice height, extracts coppice shoot and makes cuttings for extracting a slice hurst in fact.Its rootability should reach the level of group training.Group training adopts continuous subculture to cultivate, and reaches the object of physiology rejuvenation, and the mode that this embodiment adopts continuous cutting, sprout, take root completes the function of rejuvenation.
The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof
