Problems solved by technology

However, due to the great difference between my country's climate and the Netherlands, the south of my country has short and warm winters and rainy springs, which are not suitable for the growth of tulips at all; North China, Northwest, and Northeast China have cold and long winters, and short and dry springs. During the growing period, the bulbs produced are small and it is difficult to avoid degeneration

Embodiment 1

[0017] Take the bulbs of the early-flowering tulip variety Christmas Marvel after harvesting and dry them. Choose healthy bulbs without pests and diseases and put them in bamboo baskets or special plastic baskets. Store them indoors at around 20°C until September 15th. Put the bulbs in the freezer and refrigerate them at 8°C until the daily average temperature is 15°C (around November 15th in Jiangsu, Shanghai and other regions), then take the tulip bulbs out of the freezer for sowing. Carefully peel off the brown outer skin of the bulbs when sowing to prevent root damage. After the tulip bulbs are sown, if the soil is dry, water them once. After tulips emerge in early spring, they can be covered with plastic film to prevent frost damage. After the flower stems of the tulip plants are stretched, the flower buds are removed, so that more nutrients can be supplied to the growth of new underground bulbs. Harvest when about half of the leaves of the tulip plant are withered to g...

Embodiment 2

[0019] Take the bulbs of golden Apeldoorn, a mid-late flowering tulip variety, which are dried after harvesting, and choose healthy bulbs without diseases and insect pests, put them in bamboo baskets or special plastic baskets, and store them indoors at around 20°C until September 1st. Then put the bulbs into the freezer and refrigerate them at 4°C until the average daily temperature is 15°C (around November 15th in Jiangsu, Shanghai and other regions), then take the tulip bulbs out of the freezer for sowing. Carefully peel off the outer skin of the bulbs when sowing to prevent root damage. After the tulip bulbs are sown, if the soil is dry, water them once. After tulips emerge in early spring, they can be covered with plastic film to prevent frost damage. After the flower stems of the tulip plants are stretched, the flower buds are removed, so that more nutrients can be supplied to the growth of new underground bulbs.

Abstract

The cold storage rejuvenation method in the course of producing seed bulb of tulip includes the following steps: selecting health pest-free seed bulb and storing at 17-25 deg.C in the room, then placing seed bulb into cold storage chamber with 2-9 deg.C to make artificial low-temp. treatment for 45-100 days, then sowing at 8-16 deg.C, when it is sowed, its tunic is stripped and it is irrigated with thorough water once, and after the scape of the tulip plant is extended, removing bud, and when about one-half of leaf blade of tulip plant is withered, harvesting seed bulb. It can prolong the growth period duration and implement rejuvenation of seed bulb.

Description

Technical field: [0001] The invention relates to a cold storage and rejuvenation method in the production of tulip bulbs. Through artificial low-temperature treatment, the tulip bulbs can be vernalized in advance, seedlings can emerge in advance and the growth period is prolonged, so as to realize the rejuvenation of tulip bulbs. It belongs to agricultural biotechnology, especially gardening Botanical and Ornamental Horticulture. Background technique: [0002] Tulip (Tulipa gesneriana L), also known as foreign lotus, is native to Central Asia and the Mediterranean coast, and is a world-renowned bulb flower. Since the 1980s, my country has introduced and cultivated the species from the Netherlands on a large scale, but due to the influence of climatic conditions, limitations of cultivation techniques, and viruses, the phenomenon of degeneration generally occurs. Now, our country spends a lot of foreign exchange every year to import tulip bulbs from the Netherlands for one-ti...
