Embodiment 1

[0039] Embodiment one compares with comparative example one and can find that after bud piece is soaked through nutrient solution, the survival rate significantly improves, shows that nutrient solution has stronger promoting action to bud interface healing, cell growth; Embodiment 1 and comparative example 2 and Compared with the three phases of the comparative example, it can be found that the binding methods are different, and the survival rate has a certain difference, but the difference is not large, showing that the budding method of the present invention can indeed avoid the influence of rainwater and high temperature weather on the bud interface and bud pieces, and effectively ensure the survival rate. It can be found that embodiment one compares with embodiment two, after adding coconut milk and citric acid in the nutrient solution, the survival rate has a small increase, shows that coconut milk promotes bud growth and citric acid eliminates the metal on the bud interfac...

Abstract

The invention discloses a walnut summer bud grafting method. The method includes: soaking a square bud piece taken from a twig into walnut bark juice containing culture solution for a certain period of time, wherein a petiole in a certain length is reserved on a bud of the bud piece; putting the bud piece into an 'I'-shaped cut of a stock, wherein 3-4 leaves are reserved above the cut of the stock; binding the bud piece by means of two-step binding, wherein primary binding and secondary binding are opposite in plastic bag winding direction; timely maintaining and managing in a grafted bud growth process, and after survival of the bud piece, timely watering and fertilizing, and carrying out disease and pest prevention and control. By adoption of the bud grafting method, problems of proneness to rotting and serious bud piece water loss in summer bud grafting can be effectively solved, and the survival rate is increased from 60-70% to 94% or above.

Description

technical field [0001] The invention belongs to the field of grafting, and in particular relates to a summer bud grafting method for walnuts. Background technique [0002] According to the requirements of "Technical Regulations for Afforestation" (GB / T 15776-2016), walnut afforestation requires the use of improved seedlings, which are generally bred by grafting. The breeding methods include hard branch grafting and budding. Summer square budding is a kind of main breeding method. The southern summer is in hot and rainy weather, which is also the best time for summer budding. The seedlings grow vigorously, the rootstock and scion are easy to peel, and the wound heals quickly after grafting. The traditional bundling method of square bud grafting in summer uses one-time bundling and exposing the buds and petioles. If there is rain after grafting, the bundling is not strict, and the rainwater will enter the grafting joint along with the gap. Because the south is in high tempera...
