Dahlia cultivation and reproduction method

Abstract

The invention discloses a dahlia cultivation and reproduction method. The method comprises the following steps that 1, earth-nuts are selected, and germination is accelerated; 2, a seedbed is made; 3, normal buds are broke off and inserted in the seedbed, watering is conducted, the temperature and humidity are controlled, water is sprayed to preserve moisture at any time, and after the buds take roots and can absorb nutrients from a culture soil, cuttage and transplantation are conducted after twenty more days of growth of the buds; 4, enough amount of decomposed manure is applied to a plowed soil, restbalk surfaces are made according to view and admire needs, the restbalk surfaces are about 60 cm in width, furrows are about 40 cm in width, dahlia seedlings after rooting are transplanted into the restbalk surfaces, profound water is poured, the distances between the seedlings are 1 m, bamboo poles are inserted on the sides of the dahlia seedlings, seedling poles are connected to the bamboo poles, so that the stability of the seedlings is maintained, and the seedlings are prevented from being broke off; 5, water, fertilizer and cultivation management after transplantation are well conducted. According to the method, the reproduction output of the dahlia earth-nuts is significantly improved, a more extensive plantation can be achieved, and dahlias obtained through a cuttage method are more convenient for planting of landscape construction.

Description

technical field [0001] The invention relates to a plant propagation method, in particular to a dahlia cultivation and propagation method, and belongs to the technical field of plant propagation in agricultural technology. Background technique [0002] Dahlia, Asteraceae, Dahlia plant, perennial herb, also known as dahlia, geranium peony, oriental chrysanthemum, dahlia, sweet potato flower. The stem is erect and multi-branched, 120-200cm high. Originally produced in Mexico, it is also cultivated in China. It is one of the species with the most varieties of flowers, with more than 30,000 varieties. The flowering period is from mid-May to November. [0003] The traditional cultivation method of dahlia varieties is the split-root propagation method, which is simple, but the propagation coefficient is too low. Generally, only about 5 root buds can be propagated in a mound of tubers, the planting speed is slow, and the reproduction number is low. There are many consumables, but...

Problems solved by technology

[0003] The traditional cultivation method of dahlia varieties is the split-root propagation method, which is simple, but the propagation coefficient is too low. Generally, only about 5 root buds can be propagated in a mound of tubers, the planting speed is slow, and the reproduction number is low.

There are many consumables, but it is difficult to achieve large-scale planting of dahlias
