Propagation and cultivation of Tulip

Tulip, also known as dry lotus, is a world-famous bulb flower. The flower stem is strong and straight, the flower is held high, the flower shape is neat, the color is rich, beautiful and dignified. It can be planted on the ground, potted or used as a cut flower with high ornamental value.

I. Propagation technology

1. Bulb reproduction tulips are renewed every year, then dry up after flowering, and a new ball and several bulbs are born next to it. The number of bulbs varied with different varieties, less in early flowers and more in late flowers. The number of balls is also related to the cultivation conditions. Generally, seed balls are planted from September to October, but can be extended to the end of October to early November in the south. Before planting, the soil in the border is dug out 15 cm thick and covered with rotten barnyard manure and plant ash as base fertilizer. Cover the base fertilizer with a layer of fine soil, plant the seed ball on it, cover the soil, and the thickness should be 2 times higher than the seed ball. The row spacing is 14m ~ 16cm, and the plant spacing is 5cm ~ 15cm. Watering after planting can promote root formation. In winter, the north should be covered with cold protection such as horse dung and grass curtains. Remove the cold shield before thawing in early spring. There are 5 full and enlarged bulbs per pot, the soil is flush with the top of the ball, and the base fertilizer is added to the bottom of the pot. Generally, after sowing all kinds of balls in autumn, the pot can be buried in the soil to promote rooting, and irrigation will be dug out in the spring of the following year for normal management of potted plants. If you want to blossom early, you can dig it up at any time from December. If the potted plant is placed in the greenhouse, it can blossom during the Spring Festival.

two。 Sowing and reproduction should be sowed in autumn and germinated in spring after low temperature in winter. Sowing seeds in greenhouse or in open field.

II. Cultivation and management

The cultivation site should be a place with plenty of sunshine, fertile soil (sandy loam) and good drainage. 4 times of thin fertilizer could be applied before and after germination and flowering. Watering potted plants when they are dry, applying less and frequently dilute liquid fertilizer. It takes 4 years for a small ball to grow into a big ball.

Tulips can be cultivated. At present, five steps are taken in foreign countries: (1) the bulbs should be dug up a little ahead of time and immediately treated with 34 ℃ for 7 days. (2) the treated bulb was stored under the condition of 20 ℃ until the flower bud differentiated completely, and the time was about 30 days. (3) transfer to 17 ℃ for 14 days. (4) transfer to 50 ℃ condition 60 murine for 65 days. (5) finally planted in the greenhouse with soil temperature of 16 ℃ and room temperature of 18 ℃. According to this procedure, moving forward and early treatment can achieve the purpose of flowering in New Year's Day. If the florescence is postponed, the required temperature will be reduced appropriately.
