Amorphophallus konjac is mainly propagated asexually, and its offspring are mixed and degraded, which has many effects on yield and quality. The cost of konjac seed breeding is high, but fruit wine can be eliminated through heterosis to prevent taro from degradation. Breeding taro with seedling seeds can improve the propagation coefficient, but the dormancy period of seedling seeds is very long.
The seeds of Amorphophallus konjac are small stems that grow on the ear. In order to get more flowers, you need to choose 4-5-year-old taro to sow taro. Usually, after sowing in mid-March, cover the fields with straw, germinate from mid-May to early June, and remove the straw after digging. Flowers fall in bloom, and it rains when it rains. Timely prevention and control of pests and diseases, especially pests that harm flowers and fruits. Magic usually blooms from mid April to mid June. Because Amorphophallus konjac is divided into female and male, it is the best moisturizing period to remove male flowers before the inflorescence of the female parent is scattered and the pistil stigma appears mucus. At this time, the pollen of the stub can be collected on the stigma of the female parent. Flowering plants can obtain a large number of mature seeds from 65438+February to the following year1~ February.
The konjac fruit can be harvested when it turns red. Each fruit contains 1~4 seeds. Then collect seeds by washing the skin, washing the pulp and accumulating sand, and sow in the next year. Chemical hormones should be used to break dormancy before sowing. Otherwise the germination rate will be very low. Wrap the seeds with two layers of gauze, soak them in gibberellin1500mg per liter12h, then soak them in clean water, and change the water once a day.
Adventitious buds germinate on the stem of the root stalk, and the nodes, tops and edges are like wooden sticks. The survival rate of rhizomes with normal buds is higher than that with lateral buds. Rhizome propagation is one of the main methods of production at present. We often talk about the first generation of konjac seeds and the second generation of konjac seeds. The first generation of Amorphophallus konjac seeds is one-year-old Amorphophallus konjac seeds, and the second generation is two-year-old Amorphophallus konjac seeds. The first generation of konjac seeds is planted for two years, and the second generation of konjac seeds can be harvested in one year.
The specific operation method is to cut the dug rhizome into small segments with a length of 3 ~ 10 cm, and each segment has 2~3 buds. Then, after the incision is treated, vegetation can be sprayed, aired for 1~2 days, and then planted according to the density of row spacing of 30 cm and 30 cm. If it's not too cold in winter, you can stay directly and germinate and grow the next year.
