specific Embodiment 1

[0051] Specific embodiment 1: the method for breaking dormancy and increasing production of old crow petal bulbs

[0052] A bulb excavation: remove impurities from the excavated old crow petal bulbs, and select bulbs without damage by diseases and insect pests, no damage, and uniform size for subsequent use.

[0053] B. Bulb disinfection: Soak the bulbs of the old opium petals with 600 times of 50% carbendazim wettable powder for 30 minutes, then dry them in the shade for later use.

[0054] C low-temperature wet sand stratification: select river sand with uniform particles and wash it, dry it in an oven at 110°C for 4 hours, and then cool it down to room temperature naturally. Put the bulbs and river sand treated in step B at the rate of about 0.2kg of river sand per 10 bulbs The ratio is mixed evenly, the water content is kept at 70%, and it is placed in a (4±0.5)°C refrigerator for stratification treatment for 70 days.

[0055] D. Bulb germination: sow the old crow petal bul...

Abstract

The invention discloses a method for breaking the dormancy of tulipa edulis bulbs and increasing the yield. The method comprises the steps that bulbs are sterilized, and stratification is conducted by means of wet sand at the temperature of 4+/-0.5 DEG C for 70d. According to the method, low-temperature stratification is conducted on the bulbs, tulipa edulis germinating time is shortened, uniform seedlings can be obtained easily, the growth period is prolonged, the yield is increased, the problems that the period of dormancy of the tulipa edulis bulbs is long and the growing period is long when manual cultivation is adopted are solved, and powerful evidence is provided for protecting wild tulipa edulis bulb resources and promoting large-scale cultivation of the tulipa edulis bulbs.

Description

technical field [0001] The invention relates to a method for breaking dormancy and increasing production of crow's petal bulbs, which belongs to the technical field of traditional Chinese medicine cultivation. Background technique [0002] Tulipa edulis (Miq.) Baker is a medicinal plant of the genus Tulip in Liliaceae. The dried bulbs after removing the membranous cortex and villi are the Chinese herbal medicine Guangzigu. It is recorded in the literature that it has the effects of detoxifying and dispelling stagnation, promoting blood circulation and removing blood stasis. At present, the source of medicinal materials of Arthia radiata mainly depends on wild mining. In recent years, the wild resources have decreased sharply while the demand has increased year by year. Therefore, the contradiction between supply and demand has become increasingly prominent. Artificial cultivation technology is the key to solve the raw material supply of Arthia radiata. [0003] Crow's Petal...
