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 a tulip commercial bulb breeding site on the northern slope of Tianshan Mountain in Xinjiang. The altitude of the area is 2,160 meters. The meteorological data shows that the average temperature in July is 15℃, the average temperature in January is -11.1℃, and the average annual precipitation is 534.2 mm, the average relative humidity is 60%, the dryness is 2.5, and 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 type is forest grassland and grassland meadow, and the soil is black calcium Soil, the pH of the soil is between pH 7-8, suitable for tulip bulb breeding grounds;

[0020] During the "dormancy" stage of the tulip summer high temperature period, the darkness should be created and the seed bulb cultivation depth should be greater than 6cm to prevent the seed bulb from being stimulated by the sun to produce more descending st...

Embodiment 2

[0025] Choosing a breeding site for commercial tulip bulbs in the Zhaosu Basin in Yili, Xinjiang. Zhaosu is a high-level intermountain basin in the geomorphic unit, with an altitude of 1848.6 meters. Due to the increase in altitude in this area, the precipitation increases and the temperature decreases. The average annual precipitation in this area is 512.1mm, the average temperature in July is 14.6℃, the average temperature in January is -12.1℃, and the relative humidity averages 60-70%. There is stable snow in winter, and the soil is chernozem. The pH is between pH 8.0-8.3, which is a low-temperature and semi-arid ecological environment, suitable for tulip bulb breeding grounds;

[0026] During the "dormancy" stage of the tulip summer high temperature period, the darkness should be created and the seed bulb cultivation depth should be> 6cm to prevent the seed bulb from being stimulated by the sun to produce more deferring stems and deferring bulbs, which is not conducive to bulb...

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 breeding tulip bulbs Background technique [0002] Tulip is a world-famous flower. It is a short-lived bulbous flower plant of the genus Tulip in the Liliaceae family. Its scientific name is (Tulipa gesneriana) and the English name is Tulip. The currently cultivated tulips are horticultural hybrids, with more than 8,000 varieties. At present, about 300-400 varieties are produced as commodities in the world. The cultivation history of tulips in China is not long. Since the early 1980s, introduction and cultivation experiments have been carried out in many cities such as Beijing, Shanghai, Xi'an, Nanjing, Hangzhou, Kunming, Guiyang, Chengdu, Zhengzhou, etc. Due to the climate and soil of these cities The ecological conditions are not suitable for tulip bulb propagation, and the produced bulbs are not ideal. The main reason is that the rainy season comes in the middle and late stages of tulip growth, a...
