Growing method for propagating tulip

Abstract

The invention discloses a growing method for propagating tulip. The growing method comprises the specific steps of plant selection, deep-freezing, disinfection, bud scale cutting, accelerating germination of bud scales, bud scale expansion, seed ball transplantation, soil management and the like, wherein a large seed ball of tulip is subjected to deep-freezing processing before cut, and then a remarkable effect is achieved in improving propagation coefficient and cultivating a strong seedling; GA3 and NAA are applied on differentiating small bud scales of tulip to prompt differentiation of the bud scales, so that the time is shortened greatly, more than one month can be saved compared with a traditional method, the soil fertility can be improved, the plant diseases and insect pests are decreased, and then manpower and financial resources are lowered.

Description

technical field [0001] The invention relates to a method for propagating tulips, in particular to a method for quickly cultivating tulip balls by using scales. Background technique [0002] Tulip, also known as foreign lotus and grass musk, is native to the alpine regions of Iran and Turkey. It is a perennial bulbous herbaceous flower of Liliaceae. Relying on conventional bulb division propagation can only reproduce 3-5 times a year, and the reproduction speed is extremely slow, and due to virus infection (especially mosaic virus and broken color virus), the variety is degraded, and it is difficult to meet the production needs. In the production process of tulip commercial bulbs, a large number of tulip production seeds are needed. Although the production seeds can produce offspring production seeds of the same specification, due to the differences in varieties and reproduction coefficients, the degradation of the bulbs will increase with the number of generations. The numb...

Relying on conventional bulb division propagation, it can only reproduce 3-5 times a year, and the reproduction speed is extremely slow, and due to virus infection (especially mosaic virus and broken color virus), the variety is degraded, and it is difficult to meet the production needs

In the production process of tulip commercial bulbs, a large number of tulip production seeds are needed. Although the production seeds can produce offspring production seeds of the same specification, due to the differences in varieties and reproduction coefficients, the degradation of the bulbs will increase with the number of generations. The number of bulbs used for offspring production will decrease sharply, and the good traits of varieties will continue to decline. It is particularly important to expand the production scale and stabilize the quality of commercial bulbs, establish a breeding system for fine varieties, and continuously produce high-quality production bulbs; The demand for tulips is increasing, and the source of tulips every year mainly depends on imports. The production of tulips in my country is far from meeting the needs of the market.

[0003]The conventional propagation method of tulips is to divide small bulbs, but the number is limited; some species can be cut with scales, but they are often easy to rot. The cycle is long, the coefficient is low, the speed is slow, and the soil management is unscientific. At present, there are also studies on the reproduction of tulip bulbs, but the research has always had the problem of relatively long breeding time
