Post-floral bulb propagation method applied to tulip

Abstract

The invention relates to a post-floral bulb propagation method applied to tulip. The method comprises the steps of collecting post-floral bulbs free of virus, pest and disease from a flower market after cut-flower trade; removing outer seed coats through a substrate embedding method, and arranging in the ventilation condition with a room temperature of 20 DEG C and the humidity of 70% for 2 to 3 months; taking the bulbs out of a tank when the seed coat corrosion degree is 60 to 70%, screening out a substrate, classifying the seedballs, putting the bulbs into the tank after classification, and storing the seedballs in a room temperature until the seedballs are sowed in October, wherein the distance between plant rows is 7*7(centimeters) in sowing, the planting density is 120000 seeds per mu, and the covering soil thickness is 3 to 5 centimeters; instantly watering and fertilizing after the bulbs are planted; covering through plastic before surface soil is frozen; timely removing flower buds of the plants which will bloom after the temperature rises in spring and the bulbs begin growing; beginning digging the seedballs in the last ten-day period of June. According to the method, varieties of conditions of illumination, temperature, humidity and fertilization in propagation are controlled, and the domestic bulbs are utilized; thus, the problem of fewer seedball sources is solved, and the problems in after-ripening and dormancy periods of the seedballs are also solved.

Description

technical field [0001] The invention relates to the technical field of propagation methods, in particular to a propagation method for tulip bulbs after flowering. Background technique [0002] The origin of tulips is concentrated in the subtropical Mediterranean climate zone to the subtropical steppe desert climate zone. The climate is characterized by rainy winters, cool and humid springs, and hot and dry summers. When the temperature reaches or exceeds 25°C, tulips begin to wither and enter dormancy. my country belongs to the subtemperate climate zone, and the climate is characterized by drought and little rain in winter and spring, and hot summer. Moreover, the winter is long, the spring is short, and the summer comes early. The tulips planted in this climate make the vegetative growth time of the plants very short, and the bulbs are seriously degraded. To rejuvenate tulip bulbs, the vegetative growth time of tulips must be extended. my country's existing breeding metho...

Problems solved by technology

[0008] The object of the present invention is to provide a kind of breeding method for bulbs after flowering of tulips. By controlling various conditions such as light, temperature, humidity and fertilization during breeding, domestic bulbs are used, which not only solves the source of bulbs, but also Solved the problem of post-ripening and dormant period of bulbs
