Abstract

The invention relates to a method of propagation, in particular to a method for propagating tea plants (also known as camellia sinensis). The method comprises the following steps: (1) the first stage,inducing primary roots: cutting the collected branches of the tea plants into 3cm to 5cm long sprigs and carrying out the root induction for 10 to 30 minutes by growth hormones, then, cutting the pro cessed sprigs in a soilless culture substrate and further arranging the substrate in a rooting environment under artificial regulation; and (2) the second stage, inducing secondary roots: planting thewhole tea plant seed which is subjected to the first stage of induction of the primary roots in a nutrition bag filled with nutrition soil, and watering the tea plant seed for 15 to 25 days by depend ing on whether the surface of the nutrition soil turns white. By carrying out the root induction of the two stages, the invention has the advantages of simple operation, high propagation coefficient, low investment cost and easy popularization; and the invention constitutes the best way to propagate the rare difficult-to-root tea plant variety.

Description

The propagation method of a kind of tea tree

Technical field

The present invention relates to a kind of propagation method, relate in particular to the propagation method of a kind of tea tree.

Background technology

Tradition tea tree propagation method mainly adopts technology such as the land for growing field crops cuttage of little shed, propagation by grafiting, tissue culture.Little shed land for growing field crops cottage propagation, propagation by grafiting are subject to seasonal restrictions, and generally only in the winter time, can carry out spring, and there are shortcomings such as rooting rate is low, breeding success rate is low, reproduction coefficient is low in rare, the difficulty kind of taking root.Though tissue culture does not have shortcomings such as season limit, reproduction coefficient are low, there are problems such as root induction difficulty, cycle length, hardening, cost of investment height, the difficult operation of big, the non-specialized-technical personnel of equipment and instrument investment, limit its popularization.

Summary of the invention

In order to overcome above-mentioned defective, an object of the present invention is to provide the tea tree propagation method that a kind of method is simple, reproduction rate is high, cost of investment is low, be easy to promote.

In order to realize above-mentioned purpose, the present invention has adopted following technical scheme: the propagation method of a kind of tea tree may further comprise the steps: 1. the phase I is induced primary root: the brachyplast that the tea tree branch that collects is cut into 3～5cm band leaf is the root induction that heteroauxin or methyl carried out 10～30 minutes with somatotropin; Then with its cuttage in soilless culture substrate, be positioned over artificial regulatory again and take root in the environment; The temperature of the environment of taking root of described artificial regulatory is 17 ℃～28 ℃, and relative moisture is 80%～90%, and be 25～35 days standing time; Whether 2. second stage is induced secondary root: whole tea tree kind of inducing primary root through the phase I in nutritious bag, is equipped with nutrition soil in the nutritious bag, turns white to be as the criterion with nutrition soil surface and water 15～25 days; Described nutrition soil comprises by weight:

Rural area soil 85%～90%

Fertilizer 5%～10%

Ash 1%

Phosphate fertilizer 4%.

Above-mentioned soilless culture substrate comprises by weight:

Pine squama 60%～65%

Peat 30%～35%

Perlite 5%.

The present invention is through above-mentioned twice root induction, whole process of cultivation is in the artificial regulatory environment, avoided the influence of factor of natural environment, realize breeding throughout the year, the survival rate of traditional cuttage tea tree is brought up to more than 90% by 60%, and the tea shoot kind is in compost, so can be transplanted to the land for growing field crops whole year also can continue to cultivate, 98% tea shoot all can grow secondary root in the transplanted seedling, treats the branch lignification, cuts and carries out cottage propagation; This shows that the present invention is simple to operate, reproduction coefficient height, cost of investment be low, be easy to promote, and especially the breeding of the tea tree breed of taking root at rare difficulty is a kind of optimal path.

Embodiment

Below by embodiment, concrete technical scheme of the present invention is described in further detail.

Embodiment: the propagation method of a kind of tea tree, may further comprise the steps: 1, the phase I is induced primary root: the tea tree branch that will collect the throughout the year packing of preserving moisture rapidly, transport to the breeding base, summer high temperature preferably adopts ice block cooling to preserve moisture, the brachyplast that the tea tree branch is cut into 3～5cm band leaf carries out 10～30 minutes root induction with somatotropin, and somatotropin generally adopts heteroauxin or methyl; Then with its cuttage in soilless culture substrate, soilless substrate all is filled in the cave dish, and the cave dish is positioned in the environment of taking root of artificial regulatory; Soilless culture substrate comprises by weight:

Pine squama 60%～65%

Peat 30%～35%

Perlite 5%.

The temperature of the environment of taking root of described artificial regulatory is 17 ℃～28 ℃, and relative moisture is 80%～90%, and be 25～35 days standing time, and can make the tea tree branch grow 3～8 centimetres, quantity is 3～6 primary root.

Whether 2, second stage is induced secondary root: whole tea tree kind of inducing primary root through the phase I in nutritious bag, is equipped with nutrition soil in the nutritious bag, turns white to be as the criterion with nutrition soil surface and water 15～25 days; Described nutrition soil comprises by weight:

Rural area soil 85%～90%

Fertilizer 5%～10%

Ash 1%

Phosphate fertilizer 4%.

98% tea shoot all can the strong point secondary root in the transplanting tea shoot.

Claims

1. the propagation method of a tea tree is characterized in that, may further comprise the steps: 1. the phase I is induced primary root: the tea tree branch that collects is cut into the root induction that 3～5cm is with the brachyplast of leaf to carry out with somatotropin heteroauxin or methyl 10～30 minutes; Then with its cuttage in soilless culture substrate, be positioned over again in the environment of taking root of artificial regulatory; The temperature of the environment of taking root of described artificial regulatory is 17 ℃～28 ℃, and relative moisture is 80%～90%, and be 25～35 days standing time; Whether 2. second stage is induced secondary root: whole tea tree kind of inducing primary root through the phase I in nutritious bag, is equipped with nutrition soil in the nutritious bag, turns white to be as the criterion with nutrition soil surface and water 15～25 days; Described nutrition soil comprises by weight:

Rural area soil 85%～90%

Fertilizer 5%～10%

Ash 1%

Phosphate fertilizer 4%;
