Abstract
A bridge graft technique for promoting the root growth of young walnut tree includes such steps as burying 3 walnut fruits along a circumference of a circle with 20-50 cm for diameter and a circle center where a mother tree is planted, growing 3 saplings until their height is 40 cm or more, and bridge grafting between saplings and mother tree.
Description
Technical field
The present invention relates to the woody plant culture technique, especially a kind of technique of bridge grafting for promoting root growth and tree-growth of young chestnut trees.
Background technology
The walnut cultivation history is long, owing to have good economy, ecology and social benefit, is widely cultivated.But needed just begin to bear fruit in 5～7 years after the walnut plantation, it is longer to enter high yield period, under normal operation, needs 10～15 years just can enter high yield period after the plantation, the long treelet phase, is seriously restricting the performance of walnut productivity effect.
At this present situation, forefathers mainly are by enriching fertilizer, improve the soil liquid manure condition, improve the measures such as supply of soil nutrient material, promote the growth of walnut treelet, but investment is big.
Summary of the invention
Deficiency at above-mentioned prior art existence, the present invention proposes a kind of technique of bridge grafting for promoting root growth and tree-growth of young chestnut trees, it is characterized in that: carry out bridge joint by treelet and elite stand, increase complex peach treelet root system, promote the absorption of treelet root system nutrition material, complex peach treelet is grown fast.
Specifically: during plantation elite stand seedling or plantation back first autumn be the center of circle, on diameter 20-50 centimetre circumference, be equilateral triangle and bury and plant 3 iron walnuts fruits with the elite stand root, grow seedling to height of seedling reach 40 centimetres or when above and elite stand carry out bridge joint.
Described cultivation elite stand is really buried the fruit cultivation with the iron walnut or adopts the plantation of iron walnut seedling all can.
Described bridging method can mouthful connect with being abutted against or taking.
The present invention can effectively promote the quick growth of walnut treelet, and walnut enters high yield period in the ramp of treelet phase, form the large tracts of land tree crown in advance; Method provided by the invention, walnut are lower from the cost that grows into fruiting period, effect is better, not only can be applicable to walnut, also can be applicable to grow slow plant and old and feeble woody plant, and the mean height growth of application back is 1.4-2 a times of normal cultivation.
Embodiment
One, the cultivation of elite stand
The cultivation of elite stand is identical with normal complex peach kind method for planting, plants according to " seven one " standard, promptly
Select one well: select 1400 meters one 2000 meters of height above sea level, soil contain the stone amount medium more than, the plot loose, fertile, that illumination is sufficient is as planting site.
Dig a Da Tang, execute a load farmyard manure: dig length and width, dark each big pool more than 80 centimetres, apply a load farmyard manure, returning mold has prescribing adequate nutrition to guarantee the treelet phase.
Select the good seedling of a strain: select the walnut kind of the suitable development in afforestation plot, robust growth, do not have damage by disease and insect, have the nursery stock of good hereditary quality to plant.
Water one and carry water, cover a film, thin bamboo strip cage of cover: in planting, water a load normal root water and guarantee that seedling root is moistening, lid plot film is incubated, preserves moisture, and promotes that nursery stock takes root, germinates, and covers a thin bamboo strip cage and guarantees that nursery stock is without prejudice.
Two, the cultivation of extraneous root seedling
The extraneous root seedling is first autumn when planting the elite stand seedling or after the plantation, selects for use the iron walnut really to bury fruit cultivation or employing iron walnut seedling.The elite stand nursery stock requires adaptability strong, well developed root system, and root system is injury-free, could guarantee that extraneous root is effective.The extraneous root seedling really buries fruit when cultivating with the iron walnut, is the center of circle with the elite stand root, on diameter 20-50 centimetre circumference, is equilateral triangle and buries 3 iron walnuts fruits, grow seedling after, weeding 2 times, height of seedling reach 40 centimetres and when above and elite stand carry out bridge joint.
Three, bridging method
Bridging method can be with being abutted against, and the also available mouth of taking connects.
Be abutted against: the extraneous root seedling is removed bent to the smooth place of elite stand bark, elite stand and extraneous root seedling joint have stayed mark, the bark of the extraneous root of pruning seedling 1/3rd, cut long 5-6 centimetre in mouth, cut mouth what elite stand tip both sides cambium length width equated, alignment is cambium on one side, stumbles tightly with connecing film.A spring grafting 50-60 days rear port is grown, and spray was abutted against 20 rear ports and grew summer, and interface is grown and got final product cutting off more than the extraneous root sapling interface after good.
Taking mouth connects: the extraneous root seedling is removed curved to the smooth place of elite stand bark, elite stand and extraneous root sapling joint have stayed mark, to cut off more than the extraneous root sapling mark, cut and be the step type, cut a corresponding step in the elite stand mark, extraneous root sapling step is inserted elite stand fall in the step, alignment is cambium on one side, stumbles and tightly gets final product with connecing film.
Spring and summer two Ji Junke graftings behind the grafting survival, cut off extraneous root seedling interface with top, extract the following rudiment of extraneous root seedling interface out, and after 2-3 time, promptly extraneous root successfully.
Four, the management of nursery stock after the extraneous root
Outside nursery stock was managed according to general nursery stock after the extraneous root, because after the extraneous root success, the root system of nursery stock increases, seedling growth was accelerated, and was generally to plant 1.4-2 times of nursery stock, so need to strengthen supporting.Be equilateral triangle with waddy or Sinarundinaria longiuscula and be inserted in and make brace around the nursery stock, nursery stock and brace are fixed together, prevent windbreak with the rope made of hemp.
Claims (4)
1, a kind of technique of bridge grafting for promoting root growth and tree-growth of young chestnut trees is characterized in that: carry out bridge joint by treelet seedling and elite stand, increase complex peach treelet root system, promote the absorption of treelet root system nutrition material, complex peach treelet is grown fast.
2, technique of bridge grafting for promoting root growth and tree-growth of young chestnut trees according to claim 1, it is characterized in that: during plantation elite stand seedling or plantation back first autumn, with the elite stand root is the center of circle, on diameter 20-50 centimetre circumference, be equilateral triangle and bury and plant 3 iron walnuts fruit, grow seedling to height of seedling reach 40 centimetres or when above and elite stand carry out bridge joint.
3, technique of bridge grafting for promoting root growth and tree-growth of young chestnut trees according to claim 1 and 2 is characterized in that: elite stand is really buried the fruit cultivation with the iron walnut or adopts the plantation of iron walnut seedling all can.
4, technique of bridge grafting for promoting root growth and tree-growth of young chestnut trees according to claim 1 and 2 is characterized in that: described bridging method can mouthful connect with being abutted against or taking.
