It is necessary to topdress. The konjac needs a lot of fertilizer because of its long tubers.
After emergence, it is necessary to topdress in time, and use 4,000 kilograms of human and
animal fat per 667 square meters, and 5-7.5 kilograms of urea or ammonium sulfate for seedlings.
The second is to diligently cultivate (usually 3 times), diligent weeding, and keep the soil loose.


When cultivating, you should not damage the roots of konjac to avoid rotten seedlings. 1 time per
cultivating, that is, 1 time of topdressing and 1 time of cultivation. Before and after the white dew,
chasing 1 time of dilute manure, 3000 kg per 667 square meters, to enhance the growth of the
aboveground part, inhibit leaf senescence, delay the seedling period, prolong the photosynthesis time,
and promote the expansion of the bulb. Drought should be drought-resistant until drought.


The third is to prevent and treat diseases and insects. The peak period of the disease is from July to August.
The diseased plants were found to be removed in time, and some lime powder or sulphur powder was
