Grafting cultivation method for chrysanthemum morifolium

Abstract

The invention relates to a method for cultivating qie-hua chrysanthemum, and is to solve problems of high demand for water and fertilizer management, low growing amount of chrysanthemum flower and poor ability to fight disease. The invention is characterized in that: it provides a method for grafting qie-hua chrysanthemum which employs wormwood as stock and chrysanthemum of high quality as grafting material, then replanting the graft, field managing and harvesting. The graft employs wild sweet wormwood, yellow wormwood or artemisia stelleriana as root, which possesses strong adsorbent power, disease-resistant property and suitability, and for which the quality of chrysanthemum is improved.

Description

technical field [0001] The invention relates to a method for planting cut chrysanthemums. Background technique [0002] Cut chrysanthemum is one of the four major cut flowers in the world, and its consumption ranks first in the production of cut flowers. At present, the production of cut chrysanthemum in my country and the world is produced by chrysanthemum cutting seedlings and tissue culture seedlings. This method has the following problems: [0003] 1. High water and fertilizer management technology is required: cut chrysanthemums have high requirements for water and fertilizers in the production process. Domestic enterprises producing cut chrysanthemums have invested a lot in watering and fertilization to ensure the supply of water and fertilizer in the production of cut chrysanthemums , if the water (even occasionally) is high or dry, the root system of the cut chrysanthemum will be damaged, which will affect the quality of the cut chrysanthemum. Especially the cut ch...

Problems solved by technology

[0004] 2. The growth of chrysanthemum is small: the production of cut chrysanthemum requires a certain branch length and thickness, and it is produced by cutting seedlings or tissue culture seedlings. Due to the weak growth or the influence of other factors (such as heavy cropping, cultivation techniques, climate factors, etc.) ), its branching is 2-3 branches, and the phenomenon of insufficient growth often occurs, ranging from lower grades and lower prices, to severe cases that cannot be exported or listed

[0005] 3. Poor disease resistance: Due to the high planting density, high water content and poor light in the production of cut chrysanthemums, it is easy to cause leaf diseases, such as black spot, etc., resulting in lower yellow leaves and defoliation, which affects the quality of cut chrysanthemums

[0006] 4. Root self-toxicity phenomenon: cut chrysanthemum root self-toxicity occurs after repeated cropping. With the increase of production time and repeated cropping times, the toxin produced by the root system of chrysanthemum will affect the growth of chrysanthemums in the next season, resulting in reduced growth and increased pests and diseases. Crop rotation is required Or replace the soil to solve the problem, increasing the production cost
