Embodiment
[0014] Embodiment: a kind of African introduction sleeping cloth bag cutting propagation method, the steps are as follows:
[0015] (1) Sleeping cloth bag slicing seedling selection, selection seedling age is one year seedling, and seedling corm is smooth, no damage by disease and insect;
[0016] (2) The time for cutting the sleeping bag is early spring and March, and the vines and roots of the sleeping bag are cut off;
[0017] (3) The operating method of the sleeping cloth bag cutting into pieces, the sleeping cloth bag bulb is longitudinally cut into three pieces with a knife sterilized by 0.2% potassium permanganate;
[0018] (4) Cutting the sleeping cloth bag into pieces, soaking the cut sleeping cloth bag bulb in 0.2% potassium permanganate solution for 0.5 hour, and then coating the incision with a mixture of lime and plant ash, the ratio of lime and plant ash is 1:1;
[0019] (5) The treated cut pieces are placed in a cool place at 10-15°C for one day and then plante...

The invention discloses a rhizome cutting propagation method for gerradanthus macrorrhizus introduced from Africa. The method comprises the following steps: cutting off stems and root systems of annual gerradanthus macrorrhizus seedlings in early March, longitudinally cutting corms of the gerradanthus macrorrhizus into three blocks by using a cutting tool sterilized with potassium permanganate, sterilizing wounds with potassium permanganate, smearing the wounds with a mixture of lime and plant ash, planting the blocks on a sterilized substrate after the blocks are placed in shade for 24 hours, and controlling the watering quantity, temperature and illumination, wherein the blocks germinate and grow in early November, and grow well in the next April, and the corms reach 3 to 4 cm. By the novel method for improving the propagation of gerradanthus macrorrhizus, the excellent characteristics of the gerradanthus macrorrhizus variety can be maintained, and the propagation coefficient can further be increased.
Description
technical field [0001] The invention belongs to the field of plant introduction, domestication and propagation. Background technique [0002] Sleeping bag (Gerradanthus macrorrhizus) is a famous succulent bulb ornamental plant of Cucurbitaceae (Cucurbitaceae). Native to East Africa. The huge bulbs and graceful posture make visitors linger and forget to return. [0003] Since the beginning of the 21st century in our country, some succulent lovers began to introduce sleeping bags as potted plants. The Institute of Botany, Chinese Academy of Sciences, Jiangsu Province began to introduce sleeping bag seedlings from Africa in 2005 for ground planting and domestication experiments. We successfully carried out sleeping bags. Cross-pollination trials to obtain seeds. Sowing seedlings were carried out, and the first generation seedlings cultivated by themselves were obtained. We hope to make a breakthrough in other breeding methods of sleeping cloth bags (cutting propagation), in...
