Grafting method by taking maidenhair tree root system as stock

Abstract

The invention belongs to the technical field of plant cultivation, and particularly relates to a grafting method by utilizing maidenhair tree roots as stock so as to improve maidenhair tree reproduction. The method is characterized by comprising the following steps: (1) taking a selected grafting stock plantlet trunk as the center, semi-cutting the root system along the periphery with the radius of 0.5-1m, wherein the hair roots are not cut off as much as possible; (2) taking a main root as stock and remaining shoot roots, cutting off one second root at an interval of one, selecting a root system of 0.5-2.0cm, or selecting second roots with two main roots; (3) lifting the cut root system to be 5cm above the ground, backfilling the dug root soil and stepping on the soil, and straightening the selected grafting stock root with soil; (4) performing grafting after the stock root is grafted for 4-6 hours when water on the cut surface does not exude. According to the grafting method, the cleft grafting method and the cut-grafting method are adopted. The method disclosed by the invention has the benefits that the maidenhair tree reproduction efficiency is improved, and the survival rate is improved to be 98.2%.

Description

Technical field [0001] The invention belongs to the technical field of plant cultivation, and specifically relates to a method for grafting the ginkgo tree by using the root strips of the ginkgo tree to increase the reproduction of the ginkgo tree. Background technique [0002] Ginkgo trees grown from seedlings bred from ginkgo seeds not only have late flowering and fruiting and low seed yields, but also because of the large variability of seedlings obtained from seedlings, they often cannot maintain the excellent characteristics of the original plants. If grafting is used, this shortcoming can be overcome. Grafting is to insert the branches or buds of the excellent mother tree into the proper parts of the seedlings. The combination of the two forms the ginkgo plant that people hope. There are many ways to graft ginkgo, but the rootstocks are all carried out on the main stem of ginkgo saplings, and one seedling can only graft one ginkgo tree. If the root system of the ginkgo t...
