Problems solved by technology

[0003]At present, the conventional seedling cultivation cycle of tea tree clones generally requires more than one full age, and some areas require 18 months. The cycle is long and the management cost is high. From November to December, when the seedlings are planted and encounter natural disasters such as snow freezing or drought, the survival rate is low
The existing tea tree vegetative propagation technology mainly adopts short ear cuttings. When raising seedlings, new soil with a thickness of 3 to 5 cm is spread on the seedling border. It is necessary to find a suitable new soil source. The main disadvantages are: Destroy vegetation when taking soil, consume original ecological soil, and cause soil erosion; Need transportation, labor and time-consuming, high input cost

Abstract

A subsoil-free rapid propagation and seedling method of a tea tree is provided, comprising the steps of selecting area with a mean annual temperature of more than 17 degrees centigrade, an altitude of less than 700 m and soil pH of 4.5-6.0; treating strip-surface soil by one of following methods: paving 2.5-3.5 kg of weeds on the strip surface per square meter, burning weeds to sterilize at high temperature, deeply turning the soil in 25-30 cm, leveling the soil for cottage; or spraying 80-100 times of 10% of glyphosate; after 48 hours, spraying 500 times of 70% of mildothane wettable powder, deeply turning the soil in 25-30 cm, spraying 1000 times of 70% of mildothane wettable powder; after 24 hours, leveling the strip surface for cottage; (4), managing cottage and nursery by normal method. The method can protect ecological environment, reduce seedling cost and shorten seedling period, and has simple and easy technology and good effect.

Description

technical field [0001] The invention belongs to the technical field of planting, and in particular relates to a method for rapid breeding of clones. [0002] Background technique [0003] At present, the conventional seedling cultivation cycle of tea tree clones generally needs to be more than one full age, and in some areas it takes 18 months. The cycle is long and the management cost is high, and the tea seedlings emerge from the nursery every November to December. After the seedlings are planted, they encounter snow freezing or drought. The survival rate is low during natural disasters. The existing tea tree vegetative propagation technology mainly adopts short ear cuttings. When raising seedlings, new soil with a thickness of 3 to 5 cm is spread on the surface of the seedlings. It is necessary to find a suitable new soil source.
