Method for conducting freshness retaining on tea tree grafting scion

Abstract

The invention provides a method for conducting freshness retaining on a tea tree grafting scion. Timely wax sealing and thin film capping are conducted on the tea tree scion which has the ear length ranging from 8 cm to 15 cm, has one to two axillary bud growing points, is one year old or two years old, has been lignified and does not have leaves. The method includes the steps of placing beewax and paraffin wax in a pot according to the proportion of 1:1-3, heating the mixture, conducting low-fire heating after the mixture is completely melted so that the mixture can be kept not condensed, arranging the scion on a gourd-ladle-shaped leakage sieve, immersing the gourd-ladle-shaped leakage sieve into the melted wax solution, rapidly and perpendicularly lifting the gourd-ladle-shaped leakage sieve, spreading the scion covered with liquid wax to be cooled, and winding plastic thin film at the upper end of the scion where sealing wax cooling is conducted, and conducting capping for standby application. The method has the advantages that the short scion which is one year old or two years old and has been lignified is adopted, the scorching resistance, the drought resistance and the cold resistance are high compared with a semi-lignified scion which is mainly used in current grafting, the wax sealing technology is easy and practicable and low in cost; the grafting time of the scion where sealing wax freshness retaining and moisture preservation are conducted can be as long as one month, the method can adapt to the long-distance transportation and large-area grafting and the seed changing improvement, the stress resistance is improved, and the grafting survival rate is 80% or higher.

Description

Technical field: [0001] The invention belongs to the technical field of tea tree cultivation, and in particular relates to a treatment method for tea tree grafted scion sealing with wax to keep fresh. technical background: [0002] The research on transforming low-yielding tea gardens using grafting technology began in the 1970s. Zhou Hanzhong of the Jiangxi Sericulture Research Institute used the semi-lignified short ear grafting technology to transform the old tea garden for the first time and concluded that "40-year-old rootstocks can be used for grafting. The older the rootstock, the lower the seedling rate; it can be used throughout the growth period of tea trees. For grafting, summer grafting has the highest seedling rate, followed by spring grafting, and then autumn grafting". Tea tree grafting is an ideal method for transforming low-yield or low-quality and low-efficiency tea gardens. It can maximize the use of excellent scion species and the strong stress resistanc...

AI Technical Summary

Problems solved by technology

At present, tea trees are grafted with semi-lignified short spikes with half or one leaf left. The scions are similar to the branches of cutting seedlings, and have poor drought and high temperature resistance, which affects the survival rate; and it is not suitable for grafting improvement after 48 hours from the mother. , when the tea gardens for improvement purposes are far away, it is difficult to achieve large-scale grafting and planting improvement, which affects demonstration and promotion
