Detailed Explanation of Key Points of Tulip Bulb Propagation Techniques

Nursery Stock 0 views
Tulip propagation methods include bulb division propagation, seed propagation and tissue culture. The latter two methods take a long time to propagate (seed propagation takes 5 years to bloom) and are costly. Apart from special uses such as breeding new varieties and virus elimination, the bulb division propagation method is generally used. Agricultural technology recommendation. The propagation material uses small bulbs harvested in June, which are cleaned of mud, dried in the shade, and stored in a 5-10°C cold storage, with attention paid to ventilation and air exchange. Tulips prefer loose, well-aerated sandy loam soil. For bulb division propagation, choose a location with good drainage, abundant sunshine

Agricultural technology recommendation.

The propagation material uses small bulbs harvested in June, which are cleaned of mud, dried in the shade, and stored in a 5-10°C cold storage, with attention paid to ventilation and air exchange.

Tulips prefer loose, well-aerated sandy loam soil. For bulb division propagation, choose a location with good drainage, abundant sunshine and fertile soil, with a pH of 6.6-7 being optimal. Before planting, the soil must be prepared. Before soil preparation, apply 8-10 cubic meters of decomposed farmyard manure per mu, then use a tractor to rotary till, so that the soil and farmyard manure are mixed evenly.

In autumn, when the soil temperature at a depth of 15 cm drops to about 9°C, plant the small bulbs. The plant spacing is 7 cm × 11 cm, and the covering soil thickness is 4-5 times that of the bulb. Water immediately after planting, then cover with straw to help the bulbs overwinter in the field. In early March, remove the covering, and new buds emerge and begin to grow.

After the soil thaws in early spring, new buds sprout and emerge. Spray pesticide once a week to prevent diseases and pests, especially aphids. Apply fertilizer once every two weeks, using a 2-5% liquid fertilizer of calcium nitrate or potassium nitrate combined with watering for root irrigation. Stop watering until 4 weeks before dormancy.

When the plants are completely withered, dig out the bulbs, grade them according to different specifications, spread them out evenly to dry naturally, and it is not advisable to pile them up or box them first. Store them in a ventilated and dry place at 20-25°C for about 2 months, and the relative air humidity must not exceed 80%.
