Method for grafting red orange seedlings

Abstract

The invention relates to a method for grafting red orange seedlings, and belongs to the technical field of plant grafting. The method comprises the steps of tree stock variety choosing and cultivation, grafting seedling cultivation, a tree stock and grafting core technology, grafting seedling management, seedling period fertilizer and water management and leaving of seedling nursery. According to the method, grafting can be conducted in any season, the labor cost is effectively saved by more than 50%, the yield of red orange fruit trees grafted through the technology is increased by 20%-30% compared with the yield of red orange fruit trees grafted in a traditional method, the economic benefits are obvious, and a good popularization model applied function is achieved on large-scale red orange planting.

Description

technical field [0001] The invention relates to a method for grafting orange-red seedlings, in particular to a method for grafting orange-red seedlings by cutting a single bud and preparing belly grafting cutting stock, and belongs to the technical field of plant grafting. Background technique [0002] Tangerine is the dried outer pericarp of Citrus grandis Osbeckvar.tomentosa Hort. or Citrus reticulata Blanco and its cultivars of the Rutaceae plant. It is harvested after the fruit matures in late autumn and early winter. The outer pericarp is cut off with a knife and dried in the sun or in the shade. It can be used to treat wind and cold Cough, sore throat, excessive phlegm, food accumulation and alcohol, nausea and nausea, etc. It has high medicinal value and a long history of medication; it is recorded in "Drugs and Chemicals"--orange red, Xin can run rampant and dissipate stagnation, and it is recorded in "Ben Jing Feng Yuan" Orange red is specially used for lung-cold co...

Problems solved by technology

Among them, the ring branch is to choose the branches of the strong and blooming tangerine red mother tree, peel the bark at the base of the branch circularly, use fertile soil and organic fertilizer to wrap the cut part tightly, and wait for the new root to grow in the ring cut part and then transplant and reproduce. This method is only suitable for older fruit trees, and it will damage the ring-branch mother fruit tree, grow slowly, and be easily broken by strong winds; single-bud grafting is to select the young buds of fruit trees for grafting, but the traditional grafting method has no choice for rootstocks. Detailed regulations cause large variation, failure to maintain the excellent traits of the mother plant, less fruit production, and poor survival rate, etc.

Xu Xuerong et al. (2013, "Journal of Tropical Crops") carried out the research on the micro-bud grafting technology of Huazhou orange red stem tip, using pomelo, lemon, Hongjiang orange, etc. Sterilization and medium formula, rootstock seedling age and other factors on the survival rate of Huazhou Juhong stem tip grafting, this study used the microbud grafting technology, using different scion sterilization and hormone treatment methods to reduce the pollution rate, the survival rate is although There has been a certain improvement, but due to the hormone treatment in the grafting process, it is difficult to maintain the excellent performance of the mother plant, and the fruit yield cannot be guaranteed, and there are certain defects
