Problems solved by technology

What is even more regrettable is that it is more common for Amorphophallus bulbils to have flowers and leaves together in flowering plants. When there are flowers and leaves on the same plant, because the growth rate of the leaves is much faster than the growth rate of the flowers, and with the rapid growth of the leaves, the parent corm The nutrients in the buds will be quickly consumed, resulting in slower growth of seeds produced by flower buds, the fruit will not grow large, the number of seeds will be small, and many seeds will not be fruitful, and it will even be difficult for the seeds to grow and mature, resulting in a low reproductive rate

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.

Abstract

The present invention relates to an artificial inductive flowering asexual breeding method of bulbil konjak. Said method includes the following steps: making the bulbil konjak bulb undergo the process of flowering induction, inhibiting germination of lateral bud on the bulb and making the root tip grown out on the bulb be perished, promoting differentiation of top bud of konjak bulb to form flower bud, after the bulb is transplanted, artificially inhibiting flowered leafing plant growth, making flower bract can be matured and seeded so as to obtain lots of seeds capable of reproducing konjak.

Description

technical field [0001] The invention belongs to the technical field of konjac cultivation and planting methods. Background technique [0002] At present, some of the konjac bulbs artificially planted at home and abroad will bloom after 3 to 4 years of growth. Usually, the flowering and seeding process of konjac is sexual reproduction, and its cross breeding is self-pollination of the male and female stamens of the same plant under natural environmental conditions. Due to the early maturation of the pistil, the same plant is sterile, and the probability of successful hybridization of different plants is extremely limited, resulting in the ripening of konjac fruit. The rate is extremely low, and the opportunity to obtain seeds is very low. This is the main reason why the reproduction coefficient of konjac varieties such as flower konjac and white konjac is only 2 to 3 times. Therefore, the traditional konjac planting method basically adopts the small konjac bulb or the propag...
