1. Infrequent water change: the taro in hydroponic culture will be soaked in water. If not, the bacteria in the taro will proliferate. Especially in summer, the temperature will rise and the water quality will be poor. In this way, the plant is easy to be infected when soaked in unclean water, and the bottom will be rotten, which will give off a bad smell.
2. Excessive nutrition: although it needs nutrition supplement in the growth process, if it is not applied according to the needs of the plant, but excessive nutrition is added, so the bottom will be unable to bear, resulting in burnout, which leads to decay, and the smell will become bad.
3. Poor ventilation: if the growing environment is very airtight and there is no normal air circulation, even if the water inside is changed, there will be problems in the water quality, and there will also be odor.
First, remove the rotten part, cut it off with sharp scissors, wash it in clean water, pay attention to the scope of cutting not too small, remove all the positions with lesions, and then dry it in a well ventilated place. Clean the container, put it in the container again for maintenance, pay attention to the dosage when adding nutrient solution, and ensure the ventilation condition.
