Embodiment 1

[0065] An artificial cultivation method for indoor cultivation and flowering of saffron adopts a fully enclosed artificial light plant factory to cultivate saffron. The process is mainly to set different light conditions, temperature, humidity, fertilization conditions and ventilation conditions according to different growth stages of saffron indoor cultivation. To control the growth and development of saffron.

[0066] Implementation materials: saffron bulbs, light-emitting diode lights (LED).

Embodiment approach

[0067] Implementation method: the embodiment of the present invention mainly describes 4 growth stages of Saffron indoor cultivation: full dormancy period, assimilated leaf differentiation period, flower bud differentiation period, and flowering period. The spectral characteristics of each growth stage are shown in Table 1.

[0068] 1. Full dormant period: a period of one month. The light intensity is 10-40μmol / m 2 / s is gradually strengthened, the temperature is set to about 28°C, and the humidity is 76%.

[0069] 2. Assimilation leaf differentiation period: The assimilation leaf differentiation period is 45 days. The final length of leaf growth is 35cm, and the width is 0.29cm; the light intensity is 36μmol / m 2 / s, the temperature is set to 25°C, and the humidity is 80%.

[0070] 3. Flower bud differentiation period: a period of 70 days; the light intensity is 38μmol / m 2 / s, the temperature is set to around 25°C, and the humidity is 75-85%.

[0071] 4. Flowering period...

Embodiment 2

[0081] Other conditions are completely consistent with Example 1; the difference is shown in Table 2; the light condition of Example 2 is defined as 2#, and the agronomic properties of the resulting product are shown in Table 6. The functional components of the product obtained in Example 2 are shown in Table 7.

Abstract

The invention relates to anartificial light type cultivation method for indoor saffron crocus cultivation and flowering in a plant factory. The physiological needs of saffron crocus can be exactly met by strictly controllingthe light quality, light intensity and light cycle and other conditionsof a light source. In a whole dormancy period, the light intensity is set as 10-40 micro-mol/m<2>/s, the temperature is set to be about 29 DEG C and is kept for 20 days, and the humidity is 75-80%. In an assimilating leaf differentiation period, the light intensity is set as 27-36 micro-mol/m<2>/s, the temperature is set to be about 25DEG C, and the humidity is 78-83%. In a flower bud differentiation period, the light intensity is set as 27-36 micro-mol/m<2>/s, the temperature is set as 23-27 DEG C, and the humidity is about 80%. In a flowering period, the light intensity is set as 40-60micro-mol/m<2>/s, the temperature is set as 15-18DEG C, and the humidity is 75%. The pH value requirements in the periods are basically same and is 5.5-6.5. The artificial light type cultivation method makes saffron crocus high in quality and yield, and the growing time is shortened.

Description

technical field [0001] The invention relates to a technology for facility agriculture-plant factory cultivation of medicinal plants, in particular to an artificial cultivation method for indoor cultivation and flowering of saffron. Background technique [0002] Saffron, also known as crocus and saffron, is listed as a key development of Chinese medicinal materials by the country, a perennial flower and plant of the genus Crocus in the family Iridaceae. Saffron is widely used in Europe and Asia, and can be used in gynecology, development of functional food, health care cosmetics, etc. But saffron is a stigma human medicine, and its output is low. Its resources are extremely limited, making it expensive and known as "plant gold". Saffron is native to southwestern Asia. It was first cultivated by the Greeks. Our country has always been imported for medicinal purposes, and it was introduced into China during the Ming Dynasty. "Compendium of Materia Medica" listed it as medic...
