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
[0007] Since the 1980s, Chinese konjac has started to develop industrially, but due to its late start, there has been no major breakthrough in planting technology, especially in the production of seed taro, no special production has been carried out, and it is generally only harvested based on experience Collect small bulbs that can be used as taro seeds, which is not only poor in effect, uneven in quality, but also very limited in quantity
It has seriously affected the large-scale promotion of konjac; now there are large-scale enterprises to carry out tissue culture and breeding, and special breeding of seed taro, such as the patent No. 03135572.2 published "Konjac tube taro breeding technology", although the method is very effective, but the investment cost Large, high technical requirements, unable to promote to the majority of taro farmers
