Problems solved by technology

The history of tulip cultivation in my country is not long. Since the early 1980s, experiments have been carried out in Beijing, Shanghai, Xi'an, Nanjing, Hangzhou, Kunming, Guiyang, Chengdu, Zhengzhou and many other cities. The ecological conditions are not suitable for the reproduction of tulip bulbs, and the bulbs produced are not ideal. The main reason is that the rainy season comes in the middle and late stages of tulip growth, and the temperature rises, which shortens the growth period and causes serious diseases, making the bulbs smaller and more planted. The less degraded the situation, the tulip bulbs used in my country still rely mainly on imports for more than 20 years, and domestic bulbs are still difficult to meet international standards
For this reason, some scholars have also realized that the breeding site of tulip commercial bulbs should choose a low-temperature and humid environment, but there is a lack of specific indicators for site selection, and it is still at the stage of exploration

Embodiment 1

[0019] The present invention selects tulip commercial bulb breeding sites in the northern slope of Tianshan Mountain, Xinjiang. The altitude of this zone is 2160 meters. Meteorological data show that the average temperature in July in this zone is 15°C, the average temperature in January is -11.1°C, and the average annual precipitation is 534.2 mm, the average relative humidity is 60%, the dryness is 2.5, there is stable snow in winter, it belongs to the low temperature and semi-arid ecological environment, this zone is the lower limit of the forest, the vegetation types are forest grassland and grassland meadow, and the soil is black calcium Soil, the pH of the soil is between pH7-8, which is suitable for the breeding ground of tulip bulbs;

[0020] In the "dormant" stage of tulip summer high temperature period, darkness should be created and the cultivation depth of seed bulbs should be > 6cm, so as to prevent the seed bulbs from being stimulated by sunlight and produce more ...

Embodiment 2

[0025] The breeding site of commercial tulip bulbs in Zhaosu Basin, Yili District, Xinjiang was selected. Zhaosu belongs to a high-level intermountain basin in terms of geomorphology, with an altitude of 1848.6 meters. Due to the increase in altitude, the precipitation in this area is increasing and the temperature is decreasing. The average annual precipitation in this area is 512.1mm, the average temperature in July is 14.6°C, the average temperature in January is -12.1°C, the average relative humidity is 60-70%, there is stable snow in winter, and the soil is chernozem. The pH is between pH 8.0-8.3, which belongs to the low temperature and semi-arid ecological environment, suitable for the breeding ground of tulip bulbs;

[0026] In the "dormant" stage of the tulip summer high temperature period, darkness should be created and the cultivation depth of the seed bulbs should be > 6cm, so as to prevent the seed bulbs from being stimulated by the sun to produce more descending s...

Abstract

The present invention is tulip ball propagating method. Research on ecological and biological characters of tulip shows that tulip is suitable for ball propagation in low temperature and semi-arid conditions and has the average earth temperature in growth period of -6 deg.c to 18 deg.c. The present invention optimizes the growth conditions, including temperature, humidity, soil pH value, planting depth and sunshine time, so as to complete tulip ball propagation in high quality. The present invention is simple, safe and reliable, and provides new way for tulip ball propagation.

Description

technical field [0001] The invention relates to a method for propagating tulip bulbs Background technique [0002] Tulip is a famous flower in the world. It belongs to the short-lived bulbous flower plant of the genus Tulip in the family Liliaceae. Its scientific name (Tulipa gesneriana) and its English name is Tulip. The currently cultivated tulips are horticultural hybrid varieties, and there are more than 8,000 varieties. At present, there are about 300-400 varieties produced as commodities in the world. The history of tulip cultivation in my country is not long. Since the early 1980s, experiments have been carried out in Beijing, Shanghai, Xi'an, Nanjing, Hangzhou, Kunming, Guiyang, Chengdu, Zhengzhou and many other cities. The ecological conditions are not suitable for the reproduction of tulip bulbs, and the bulbs produced are not ideal. The main reason is that the rainy season comes in the middle and late stages of tulip growth, and the temperature rises, which short...
