Embodiment 1
[0029] Embodiment 1: After the fall of frost, 200 plump bulbs with an individual weight of more than 1 kilogram are selected, and after 3 to 4 days in the sun, the bulbs are layered on a light-transmitting dry wooden frame (or other similar environments) Place storage. It should be noted that the bulbs to be artificially induced must not be cut into pieces, and the bulbs should not be partially rotted as much as possible, so as not to reduce the energy reserve of later flowering plants. During winter, the differentiation and growth of corm terminal buds is slow. At this stage, it is important to prevent the corm from being damaged by freezing in an outdoor environment below zero (0°C) at night. In practice, the corm should be placed in a relatively warm, ventilated and light-transmitting place. s room.
[0030] When spring comes, the temperature rises, and the highest temperature during the day reaches 10°C-25°C, preferably around 15°C-22°C, put the bulbil bulbs in the sun or...
Embodiment 2
[0032] Embodiment two: adopt hydroponics. The flower bud induction process of bulb is the same as embodiment one. Amorphophallus konjac tubers have strong water resistance, because the nutrients required for seed growth can be completely derived from the parent corm, so the method of soaking in water can be used to obtain mature seeds conveniently.
[0033] Select 20 flowering bulbil konjac balls that have been induced and treated, and soak their stems in water. The container used can be a plastic bucket or a plastic bag. The height of the water added is about 1 / 2 to 2 / 3 of the height of the bulb. Konjac bulbs are completely submerged in water. Otherwise, the roots of the flowering plants are prone to rot and the interruption of seed growth. Place the soaked bulbs outdoors in a natural environment where the sun can shine. In the early stage of seed growth from May to September, water should be replenished frequently to ensure that the bulbs need enough water in the provisio...
Embodiment 3
[0034] Embodiment three: adopt the artificial intensive cultivation of sand burial method. After harvesting, select 100 bulbs with an individual weight of more than 2 kilograms as parent bulbs for induced breeding. The flower bud induction process of bulb is the same as embodiment one. Bury 4 / 5 of the corm with buds in the mountain sand or river sand, so that the root of the plant flower stem and the upper part of the corm are slightly exposed to the air. During the entire growth period of the plant, water frequently according to the degree of dryness and wetness of the sand, so that the bulb can provide nutrients normally during the seed growth. Flowering plants can obtain a large number of mature seeds from December of the current year to January to February of the next year. The method achieves more than 95% seed maturity.
