Abstract
A stevia rebaudiana single-joint half-stem cottage method is characterized in that strong seedlings of stevia rebaudiana are selected from a farmland and are cut off by about 3cm top tips for conventional cottage; stems are cut into single-joint stem sections with the joint as the unit, the cut stem sections are longitudinally split into two halves from a central line of two opposite leaves, and single-joint half-stem cutting spikes to be planted can be obtained; and robust new seedlings can grow by cutting the single-joint half-stem cutting spikes. The stevia rebaudiana single-joint half-stem cottage method can use limited stevia rebaudiana seedling resources and improve propagation efficiency.
Description
Technical field
The invention belongs to the cultivation of plants technical field, specifically a kind of method of the stevia stem being carried out single-unit half stem cuttage.
Background technology
Stevia is a kind of important sweetener raw material crop.Adopt cottage propagation can keep the good strains of seeds of stevia kind, the stevia large-scale breeding of producing at present is all take cuttage as main.In order to improve the efficient of cottage propagation, after we carry out the single-unit intercept with stevia, to carry out again vertical profile and process, then cuttage has obtained good effect.
Summary of the invention
The purpose of this invention is to provide a kind of than the more efficient stevia rapid cuttage of prior art propagation technique.
A kind of stevia single-unit half stem cuttage is achieved in that
1. stevia single-unit half a stem cuttage comprises and selects seedling to cut seedling, cuttage and seedling disk management three phases, it is characterized in that cutting the seedling stage, first seedling is cut into single stem segment, again the stem section is cut into half stem.
2. select seedling to cut seedling: to choose the strong sprout of stevia from the field, clip the top tip, separately cuttage.Remaining part take joint as unit, is cut into the stem section of single-unit, then with the stem section that is cut into from the medium line vertical profile of two opposite simple leaves into two, standby plugged ear of planting.
3. seedling dish cuttage: plugged ear is inserted foam plastic seedling, every lattice cuttage one seedling.The matrix of seedling-cultivating tray is the peat composed of rotten mosses, vermiculite, perlite mixture.Water permeablely after the cultivation, and add a cover sunshade net and shelter from heat or light.
3. seedling disk management: regulate moisture every day after the cuttage, keeps culture matrix moistening.Water every the 5 days composite fertilizer's solution with low concentration after 5 days.Progressively lift sunshade net after one week.Cuttage rooting and grow sprouting after carry out field-transplanting.
Beneficial effect of the present invention:
Benefit of the present invention is to utilize the seedling source of same quantity, and cuttage goes out the newborn seedling of more stevia, thereby raises labour efficiency.
Embodiment
The single-unit half stem cuttage of embodiment 1. Wantian No.1 stevia
Choose the strong sprout of Wantian No.1 stevia from the field, the top tip of clipping about 3cm carries out normal cutting propagation, and the part of remainder take joint as unit, is cut into the stem section of single-unit.With the stem section that is cut into from the medium line vertical profile of two opposite simple leaves into two, standby plugged ear of planting.The plugged ear cuttage of getting 100 single-unit half stems is to foam plastic seedling, and every lattice cuttage one seedling take the single-unit plugged ear of same quantity as contrast, repeats 3 times.The matrix of seedling-cultivating tray is the peat composed of rotten mosses, vermiculite, perlite mixture.Water permeablely after the cultivation, and add a cover sunshade net and shelter from heat or light.Regulate moisture every day, keep culture matrix moistening.Water every the 5 days composite fertilizer's solution with low concentration after 5 days.Progressively lift sunshade net after one week.Cuttage rooting and the sprouting that sends from axil are long to the long field-transplanting that namely carries out of 5cm.The result, it is 100% that average planting percent is processed in the single-unit cuttage, and the average planting percent of single-unit radius cuttage is 97.4%, i.e. 100 strains of per 100 young plant seedlings are processed in single-unit cuttage, and the stipes of same quantity adopts single-unit half stem cuttage to get final product seedling 194.8 strains, and contrast improves 94.8%.
The single-unit half stem cuttage of embodiment 2. B1 stevia kinds
Choose the strong sprout of stevia B1 from the field, the top tip of clipping about 3cm carries out normal cutting propagation, and the part of remainder take joint as unit, is cut into the stem section of single-unit.With the stem section that is cut into from the medium line vertical profile of two opposite simple leaves into two, standby plugged ear of planting.The plugged ear cuttage of getting 100 single-unit half stems is to foam plastic seedling, and every lattice cuttage one seedling take the single-unit plugged ear of same quantity as contrast, repeats 3 times.The matrix of seedling-cultivating tray is the peat composed of rotten mosses, vermiculite, perlite mixture.Water permeablely after the cultivation, and add a cover sunshade net and shelter from heat or light.Regulate moisture every day, keep culture matrix moistening.Water every the 5 days composite fertilizer's solution with low concentration after 5 days.Progressively lift sunshade net after one week.Cuttage rooting and the sprouting that sends from axil are long to the long field-transplanting that namely carries out of 10cm.As a result, it is 98.4% that average planting percent is processed in the single-unit cuttage, and the average planting percent of single-unit radius cuttage is 96.3%.Be that 98.4 strains of per 100 young plant seedlings are processed in the single-unit cuttage, and the stipes of same quantity adopts single-unit half stem cuttage to get final product seedling 192.6 strains, contrast improves 95.2%.
