Grafting method for fruitless sycamore and establishment process of spike gardens

Abstract

The invention discloses a grafting method for fruitless sycamore and an establishment process of spike gardens. The grafting method and the establishment process of spike gardens comprises following steps: selecting stocks: selecting sycamore as stocks for provisonal planting, and cutting the I-shaped incision in the tstocks and repeating cutting 4 to 8 I-shaped incisions spiral upward for 90 DEG;selecting 1 year of fruitless sycamore as a scion; cutting a square bark scion with the same height as the stock incision and shorter than the stock incision on the scion with a small knife, inserting and fixing the square scion, wrapping it with wet yarn, and wrapping it with plastic wrap; using the nutrient solution to water the root soil of the provisonal planting stock and the gauze on the outside of the graft until they are completely wet; the scion normally grows sprouts or roots are removed, the gauze is removed, the nutrient solution is continued to be sprayed, and the young leaves are grown at the grafting site for normal photosynthesis. The grafting method of the invention can effectively improve the survival rate of the scion, and the scion after grafting grows fast and retainsthe original traits.

Description

technical field [0001] The invention relates to the technical field of plant grafting, in particular to a method for grafting a fruitless plane tree and a technique for establishing a spike nursery. Background technique [0002] Grafting, one of the methods of artificial vegetative propagation of plants. That is to graft the branches or buds of one plant onto the stem or root of another plant, so that the two parts connected together grow into a complete plant. Grafting is carried out by utilizing the wound healing function of the plant. During grafting, the scion should be closely combined with the cambium of the rootstock to ensure the survival of the scion. The connected branches or buds are called scions, and the grafted plant body is called rootstock or platform wood. When scioning, seedlings with 2 to 4 buds are generally selected, which become the upper part or top of the plant after grafting; the rootstock becomes the root part of the plant after grafting.

Yang Liucheng et al. ("No Ball Platanus Seedling Technology", Northern Horticulture, 2008, 1: 105-106) disclose a kind of grafting method suitable for annual Platanus seedling rootstock, which does not involve high grafting technical measures; Research on Sterile Varieties of Tong Gao, Journal of Xiaogan University, 2002, 22(3): 60-61), Lili Liang et al. ): 24), Wang Qiming, etc. ("Study on the Grafting and Transformation Technology of the Street Tree Platanus syringa with less balls", Journal of Shangqiu Normal University, 2001, 17(4): 100-102), Liu Jian ("How to make the two-balled Platanus flocculation non-polluting Environment", Chinese Flower Bonsai, 2007, 12: 33) all belong to the category of grafting technology to transform the existing street tree Platanus (diameter above 10cm) by high grafting and crown replacement. Grafting Technology of Scale-scale Production of Seedlings of Platanus annulus

In the grafting method, Hua Guang'an's research pointed out that the survival rate of rectangular bud grafting is the best, but this method requires two blades to take buds at the same time, which is cumbersome and inefficient, which is not conducive to large-scale grafting of seedlings
