Problems solved by technology

In 2006, domestic and foreign demand for fresh konjac was 900,000 tons, while the output was only 520,000 tons, far from meeting the demand
Patent No. 02103808.2 has announced "a method for early maturity of konjac", which adopts the method of prolonging the storage period of the seed taro for one year, so that the seed taro can germinate in advance after sowing, so that the konjac matures earlier. Although this method is effective, But there are two problems, the first is that the storage period is extended for one year, which increases the production cost, and the second is that the storage time is long, and the occurrence of plant diseases and insect pests in taro will greatly increase, which increases waste

Embodiment 1

[0015] Take 200kg of seed taro and store it in a storage room with a temperature of 20°C. On March 1 of the following year, soak the seed taro with 5‰ of thiourea solution for 5 hours, then take it out and dry it, and then use 0.5‰ of potassium permanganate solution Soak the seed taro for 22 hours, then take it out and dry it; then carry out germination treatment, and plant it in the field on March 10, and buds and leaves will emerge at the end of March, which is one month earlier than the ordinary planting method, prolonging the growth period of konjac plants.

Embodiment 2

[0017] Take 300kg of seed taro and store it in a storage room with a temperature of 25°C. On March 1 of the following year, soak the seed taro with 8‰ of thiourea solution for 3 hours, then take it out and dry it, and then use 0.5‰ of potassium permanganate solution Soak the seed taro for 24 hours, then take it out and dry it; then carry out germination treatment, and plant it in the field on March 10, and buds and leaves will emerge at the end of March, which is one month earlier than the ordinary planting method, prolonging the growth period of konjac plants.

Embodiment 3

[0019] Take 150 kg of seed taro and store it in a storage room with a temperature of 23°C. On March 1 of the following year, soak the seed taro with 6‰ of thiourea solution for 4 hours, then take it out and dry it, and then use 0.5‰ of potassium permanganate solution Soak the seed taro for 24 hours, then take it out and dry it; then carry out germination treatment, and plant it in the field on March 10, and buds and leaves will emerge at the end of March, which is one month earlier than the ordinary planting method, prolonging the growth period of konjac plants.

Abstract

The invention relates to a method for terminating the dormancy period of seed konjac ahead of time, comprising warm temperate storage and dormancy-breaking treatment. The method specifically comprises the steps of: when the seed konjacs are overwintered and stored, controlling the temperature of a storage room in the range of 20-25 DEG C, and dipping in thiourea solution and then potassium permanganate solution before sowing and germination promotion. The method has the beneficial effects that: the dormancy period of the seed konjacs can be shortened by about 1 month through the warm temperature storage, the dormancy state of the seed konjacs can be quickly broken through the liquid agent dormancy-breaking treatment, therefore, the dormancy period of seed konjac can be terminated ahead of time, the development and growth period of konjac plants is prolonged, the nutriment absorbing time of konjac corms is lengthened, and the konjac yield is improved.
