A kind of cutting chrysanthemum seedling breeding and cultivation method

Abstract

The invention provides a cut-flower chrysanthemum morifolium seedling breeding and cultivating method. The cut-flower chrysanthemum morifolium seedling breeding and cultivating method includes steps of root cutting, breeding, planting and growth management, and is characterized in that during root cutting, adopting a scion stem long in 10cm, disposing the entire scion stem in the following rooting liquids including distilled water+0.4-0.6mg / L of IBA (indole butyric acid)+0.4-0.6mg / L of NAA (naphthalene acetic acid)+3-4ml / L of azoxystrobin+2-3ml / L of gold ridomil, and cutting after soaking for 10-15 minutes. The scion stem which is long is easy to root, root distribution is uniform and strong, bacteria carried with the stem are effectively killed, cuttage diseases are reduced, death rate at the seedling stage is decreased, cut-flower quality is kept constant, the time from cuttage seedling planting to cut-flower harvesting lasts 70 days, and five batches of the cut-flower chrysanthemum morifolium can be continuously produced in a year. Besides, rot of the seedlings is reduced, death rate is decreased to 2-3%, and plants are strong and healthy, so that yield of the cut-flower is increased to 75-90%.

Description

technical field [0001] The invention relates to a multi-head cut chrysanthemum seedling breeding and cultivation method, which belongs to the technical field of plant breeding and cultivation. Background technique [0002] The large-scale production of multi-headed cut chrysanthemums usually uses 6 cm spikes for cuttings. After breeding, rooting and seedlings are transplanted and planted, and after vegetative growth and reproductive growth, the cut flowers can be harvested. It takes 85 days from planting to harvesting of cut flowers. Up to 4 rounds of multi-headed cut chrysanthemums can be produced continuously every year, and the seedlings are easy to rot after transplanting. The dead seedling rate is usually 5-8%. When the cut flowers are harvested, they are qualified The rate (including 4 grades of 2L, L, M, and S) is only 55-60%. Cut chrysanthemum per crop per 667m 2 34,700 plants are planted, every 667m 2 Plant 138,800 plants, but only 76,000 to 83,000 cut flowers ca...
