Abstract

The invention discloses a method for promoting chrysanthemum cutting rooting. The method comprises: taking a top cutting from a chrysanthemum stock plant whose nutrition and growth are good; soaking the lower end of the cutting in a NAA and IBA mixed liquid for 10-15 min, disinfecting to reserve; mixing perlite, vermiculite, and peat in mass ratio of 1:2:3-4 to use as a cutting medium, disinfecting to reserve; punching small holes in depth of 4-6 cm on the disinfected cutting medium by using a thin bamboo stick; inserting the lower end of the disinfected cutting in the small hole, inserting a cutting in each small hole, properly pressing the cutting, pouring water over the cuttings, using carbendazim in 1000 times to disinfect; covering a polyethylene film to maintain air humidity, and covering a sunshade net, in a rooting process, maintaining soil temperature at 18-20 DEG C, air temperature 15-18 DEG C, and relative humidity 85%-90%. The top cuttings whose nutrition and growth are good are used for cutting, so as to promote rooting percentage.

Description

A kind of method promoting chrysanthemum cuttage root-taking

Technical field

The present invention relates to flowers cuttage technique field, be specifically related to a kind of method promoting chrysanthemum cuttage root-taking.

Background technology

Chrysanthemum is composite family, Chrysanthemum herbaceos perennial, and stem is upright, and branch or not branch, by pubescence.Leaf is avette to lanceolar, and pinniform is shallow to be split or partly split, and have short handle, adaxial surface of the leaf is by white pubescence.Capitulum, not of uniform size.Phyllary multilayer, outer outside is by pubescence.Ligulate flower color is various.Tubular flower is yellow.Chrysanthemum romantic charm is quaint and elegant, gorgeous, is described as " spending middle gentleman ", has very high ornamental value.Along with the raising day by day of people's living standard, afforestation, beautify, the demand of chrysanthemum increased day by day in brightening.Nowadays, chrysanthemum has become one of world flower industry " four large cut-flowers ".

Chrysanthemum breeding has vegetative propagation and sexual propagation 2 kinds.Sexual propagation is used for crossbreeding, and general production above seldom uses.Vegetative propagation comprises cuttage, plant division, grafting, press strip and tissue cultures etc.Cuttage is the regeneration capacity utilizing chrysanthemum nutrition organs to have, and the part cutting stem is inserted in matrix, makes it root into the propagation method of new plant.Cuttage can keep the merit of kind, and reproduction coefficient is higher, becomes the optimum Propagation Methods of the large-scale industrialized production of chrysanthemum.

Summary of the invention

The object of this invention is to provide a kind of method promoting chrysanthemum cuttage root-taking, to improve chrysanthemum cutting plantation.

The present invention is by the following technical solutions:

Promote a method for chrysanthemum cuttage root-taking, comprise the steps:

Step one, take top cuttings from nutrition and well-grown chrysanthemum maternal plant, each cuttings 8 ~ 12cm, 5 ~ 6 joints, retain 2 ~ 3 blades, otch is 40 ~ miter angle;

Step 2, step one cuttings lower end is immersed in 10 ~ 15min in the mixed liquor of NAA and IBA, sterilizes afterwards for subsequent use;

Step 3, using perlite, vermiculite, peat in mass ratio 1:2:3 ~ 4 mix as cutting medium, sterilize for subsequent use;

Step 4, with thin bamboo pole cutting medium after sterilization being inserted the dark duck eye of 4 ~ 6cm, seeding row spacing is 9 ~ 11cm × 5 ~ 6cm;

Step 5, by the duck eye of the cuttings lower end inserting step four after sterilization, each duck eye inserts a cuttings, suitably compresses, waters permeable, sterilizes with the carbendazim solutions of 1000 times;

Step 6, outer cover polyethylene film are to keep air humidity, and covered with sunshade net, keep soil temperature 18 ~ 20 DEG C in rooting process, temperature 15 ~ 18 DEG C, relative moisture 85% ~ 90%.

In the mixed liquor of NAA and IBA described in step 2, NAA mass concentration is 5 ~ 10mg/L, IBA mass concentration is 20 ~ 30mg/L.

Beneficial effect of the present invention:

1, maternal plant nutrition and cutting position have material impact to chrysanthemum cutting plantation, and the present invention adopts the top cuttings taked from nutrition and well-grown maternal plant to carry out cuttage, facilitates rooting rate.

2, the present invention adopts perlite, vermiculite, peat 1 ~ 2:1 in mass ratio ~ 2:3 ~ 4 to mix as cutting medium, ventilative good with drainage, evenly keeping moisture, providing safeguard for taking root.

3, cuttings lower end is immersed in the mixed liquor of NAA and IBA and carries out cuttage again after 10 ~ 15min by the present invention, promotes taking root and the survival rate of seedling of chrysanthemum cuttings.
