What is the method of jujube tree single-bud cutting and grafting?

  The wild jujube is used as the rootstock, and the single-bud cut-off method is used to graft the pear (winter) jujube wax to seal more than 10,000, and the survival rate is over 92%. In the same year, the height of the seedling was 74cm and the thickness was 8.5mm. Compared with the traditional method of inserting the tongue, it has a long grafting period (the rootstock can be grafted before and after peeling), the grafting rate is high (the thickness of the rootstock can be), and the moisturizing is good (wax seal, plastic) The membrane double layer moisturizing) and other advantages. So what is the method of grafting the single buds of jujube trees?

specific method:



    1. Prepare before picking up



    From the beginning of February to the beginning of March, the annual and secondary branches with pure varieties, strong growth, good quality and no pests and diseases were cut and cut into 20 cm long branches. Use high-quality paraffin to set the water bath (simplified), after the wax liquid boils, quickly immerse the wax in the iron fence, and quickly remove it. After cooling, collect and let cool and put it into standby. Remove the weak plants and weeds around the jujube roots before picking up, cut the rootstock 6-10cm, and cut off the branches.



    2, grafting method



    From the beginning of April to the middle of May, it is suitable for grafting. Take a scion and cut it into a double-slope wedge shape at 1-2 cm below the bud. The long-cut surface is cut about 3-6 cm from the rootstock and cut obliquely to a length of about 2 cm and the depth of the rootstock is 1/2-1/ 3 cuts; insert the long cut face of the scion into the cut to make the layers aligned; use the mulch strip to wrap the wound tightly. Only one layer is placed on the bud, and when the bag is placed at the bud, the mulch is pulled hard. In this way, the germination will eject itself, without the need to manually break the membrane, which saves labor and improves the survival rate.



    3, after the management



    The germination of the anvil buds should be removed in time after 10-15 days. When the jujube bud grows to about 20cm, remove 5cm and tie the column to prevent wind folding. When the plastic film wrapped affects the thick growth of the jujube branches, it is untied in time.
