Embodiment 1

[0046] Embodiment 1 Utilizes the method for the effective accumulated temperature of the tulip growth period to produce bulbs

[0047] The present invention selects Zhaosu County, which has a low-temperature semi-arid climate type with an average temperature of 14.6°C and a dryness of 2.46 in July, from 2006 to 2015, and conducts the introduction and domestication cultivation experiments of 43 tulip varieties, including early flowering varieties. 2, 27 middle-flowered and 14 late-flowered, were planted uniformly, and their emergence dates were April 13, and then the effective accumulated temperature during the flowering period and growth period was counted, as shown in Table 2.

[0049]

[0050] In the actual management process, tulips are densely planted to control the coverage of tulip stems and leaves to 95-100%, and the ground is covered with 3-5cm thi...

Embodiment 2

[0053] Embodiment 2 Utilizes the effective accumulated temperature of tulip flowering stage to promote its cultivation and regulation of flowering stage

[0054] Tulips promote the control of the cultivation flowering period. Due to the differences in tulip types and variety habits, it is often difficult to control from planting emergence to flowering period. Within a certain temperature range, use temperature to control the flowering period. From the effective accumulated temperature to the flowering period and the temperature set during planting, the exact flowering date can be calculated by using the N=K / T calculation formula.

[0055] Select the love of the world (Word'sFarourite) variety and adopt the method of the present invention to cultivate it, then count the effective accumulated temperature from emergence to flowering stage as 348°C, and control the average temperature from emergence to flowering stage in daily management to be 13.6°C , by calculation, the arrival ...

Abstract

The invention discloses a method for producing bulb and controlling florescence by utilizing effective accumulated temperature in tulip growing period, wherein the method for producing bulb by utilizing effective accumulated temperature in tulip growing period comprises the steps of determining the effective accumulated temperature at the tulip growing period; selecting a low temperature semi-arid climate type area that has an average temperature of 12-16 DEG C and a dryness fraction of 2-3 in July as the production base on the basis of determining the effective accumulated temperature at the tulip growing period; planting the tulip to control the tulip stem and leaf coverage between 95-100%; and covering the organic matter 3-5cm thick. After grasping the effective accumulated temperature at the growing period of the cultivar and the set temperature when planting, namely the temperature of tulip at growing period, calculate the accurate blossom date by the following formula: N=K/(T-C).

Description

technical field [0001] The invention belongs to the field of flowers, and in particular relates to a method for producing bulbs and controlling the flowering period by utilizing the effective accumulated temperature in the growth period of tulips. Background technique [0002] Tulip (Tulipa-gesneriana.L) belongs to Liliaceae, tulip genus, is a kind of short-lived plant. There are few guidances for the observation, research and utilization of effective accumulated temperature of plants in my country, especially for the introduction and domestication of tulips for the purpose of breeding commercial bulbs, the ecological and biological characteristics of the introduced tulip varieties, and the accumulated temperature required for each phenological development stage Without knowing the situation, there is a lot of blindness in the introduction, cultivation and field management, and the success rate is very low. It has been more than 30 years since the early 1980s in our country....
