Abstract

Stock length 27 30cm of seedling, with beating the cultivation of oblique method, trunk and 55 60 degree angles of ground angle, overwhelms that trunk crooked radian is little, bend height is conducive to bury anti-severe winter, reduction injured trunk probability again；Increasing the stock root on ground level and do length, improve grafting mouth and the distance on ground and the earth that makes grafting mouth be difficult to be deposited buries, tree does not grow secondary root (bound feet) and saves the amount of labour used and set body with reducing incised wound.

Description

Lengthen stock grafting Fructus Vitis viniferae seedling cultural method

Technical field

Fructus Vitis viniferae seedling is cultivated.

Background technology

In view of existing market adopts traditional stock grafting Fructus Vitis viniferae seedling, stock length 15 20cm, stock root during cultivation Dry vertical and interface close proximity to ground, its shortcoming is:

1) winter, bending trunk is cold-proof to overwhelming rear earthing, limited because taking the earth volume of garden mould, so it is curved to force down trunk as far as possible Bent bow height, increases thick along with the age of tree increases trunk, and bending trunk is the most difficult, it is easy to injured or even the trunk that fractures；

2) raining and water and wash away garden mould and buried seam by alluvial, scion and grafting mouth etc. grow secondary root, secondary root Being born in earth's surface more and relatively can not resist cold, secondary root can not be survived the winter.Secondary root is robbed again and is obtained the nutrient substance that trunk is descending, causes deep layer root System can not get enough energy nutrient and stops growing, and root system is dead in the course of time.Removing secondary root i.e. increases time cost and again can Cut the dry cortex of root and cause antibacterial, Virus entry wound to cause tree easily to catch an illness.

Summary of the invention

Seedling stock length 27 30cm of the present invention, does long 9 10cm than traditional seedling stock root.Stock and ground Angle 50 60 angle, buries the most anti-severe winter, and trunk bending radian is little to be overwhelmed easily, and the part grown is basseted, and carries The distance on high interface and ground and make grafting mouth away from the earth of alluvial, so not growing secondary root；

Cultural method:

1) leveling land fertilising, spacing in the rows, line-spacing are identical with traditional method.Digging strip ditch groove depth 18cm by line-spacing, every strain is all pressed anti- Severe winter, pile things on fell direction one along tilting, and during by 56 leaf seedlings, stock root is dry plants into groove with 60 degree of angles of ground inclination In, stock is in subsurface length 21cm, and 9 6cm on ground, on ground level, stock fences up to first leaf wet soil, soil Heap top is enclosed below the bottom leaf of Seedling, base diameter about the 15cm of taper mound, slightly firmly compacting；

2) until seedling grows the 8th 10 young leaves, start the soil removing around seedling, reduce the diameter of mound, not one Secondary withdraw from, then remove soil again after growing the 11st 14 young leaves, in three times mound is withdrawn from, expose stand-down top stock root Dry, at this moment seedling is just planted and lives；

3), when seedling grows to the first bracing wire height of frame, guide trunk to do direction along stock root and be strapped in first bracing wire.Tree Dry when growing tall again, bend towards bondage slowly to the second bracing wire of frame, kidnapping is identical with traditional method later；

4) transfer the grafting membrane of seam bondage, must cut open when the Second Year summer after field planting, unsuitable too early, cut a little later Opening energy makes interface fully heal, and does not affect the growth of tree, wet soil enclosing interface transitions a period of time to be used after taking off grafting membrane Recession removes；

5) the unaccounted management of every this method, diseases prevention and treatment etc. are identical with traditional cultivation method.The present invention and traditional method one Sample, it is applicable to whole grape varieties of cold-proof regional culture；
