Konjac cultivation method

Abstract

The invention discloses a konjac cultivation method. When konjacs are harvested in the first year, each konjac of a single tuber with the weight larger than a predetermined value is harvested, each konjac of a single tuber with the weight smaller than the predetermined value remains in a field, and the konjacs remaining in the fields serve as seeds to be cultivated in the next year.

Description

field of invention [0001] The invention relates to a plant cultivation method, in particular to a konjac cultivation method. Background technique [0002] Konjac is a perennial herbaceous monocotyledonous plant of Araceae. The underground stem of konjac is rich in glucomannan, pectin, alkaloid, starch, 17 kinds of amino acids and various trace elements. Konjac is the only one found so far that contains a large amount of glucomannan Glucomannan has a variety of unique physical and chemical properties such as water solubility, water retention, thickening, stability, suspension, gelation, and bonding. Therefore, konjac can be used in medical, chemical, food, petroleum, textile and other industries. Broad market prospects. Due to market demand, large-scale planting of konjac has begun in various places, but the commonly used cultivation methods for konjac have relatively high requirements for land. It is required that the land for planting konjac has not been planted with konja...

Problems solved by technology

Due to market demand, large-scale planting of konjac has begun in various places. However, the commonly used cultivation methods of konjac have relatively high requirements on the land. It is required that the land where konjac is planted has not been planted with konjac, vegetables, flue-cured tobacco, potatoes, radishes, etc. Solanaceae or The arable land for vegetable crops, and the crop rotation period is 3-5 years, so there is very little land suitable for planting konjac, and the planting base is not stable

In addition, in the commonly used cultivation methods of konjac, the seeded taro will go through the links of harvesting, sorting, transportation, storage, and sowing. In these links, the seeded taro is easily damaged and rotted, and even the spread of germs in these processes leads to soft rot. The disease frequently breaks out, and the loss caused by soft rot is generally 30%-50%, and severe cases can reach 80%, or even no harvest. There is no effective control method at present.

The lack of land suitable for planting konjac and the loss caused by the outbreak of soft rot have seriously restricted the development of konjac planting
