Taro, perennial tuberous plants, often cultivated as an annual crop. Leaf blade peltate, petiole fat, plant base to form a shortened stem, gradually accumulate nutrients fertilized into a fleshy bulb spherical, or tuberous and so on. But to the lower nodes of the axillary buds of the strongest activity, the first tiller, in the appropriate conditions of wet, not drought-resistant, more shade-tolerant, and has the characteristics of aquatic plants, paddy fields or drylands can be cultivated. Root absorption is weak, the entire growth period requires adequate moisture; wide adaptability to the soil, to fertile and deep, strong water retention of clay soil is preferred; taro high temperature and humid environment, in 15 ℃ began to germinate, the growth period requires a temperature of 20 ℃, the bulb at 27 ℃ -30 ℃ when the development of good.

Taro is native to the high temperature and wetland zone, in the long-term cultivation process formed a water taro, water and drought taro, dry taro and other cultivation types. But whether water taro or dry taro need high temperature and humidity environmental conditions, 13-15 ℃ taro bulb began to sprout, seedling growth temperature of 20-25 ℃, the hair of the growth of the period of the appropriate temperature of 20-30 ℃. A large temperature difference between day and night is favorable to the formation of the bulb, bulb formation period to 28-30 ℃ during the day, 18-20 ℃ at night is the most suitable.

Water taro is suitable for growth in water, need to choose paddy fields, low-lying land or ditch cultivation. Dry taro can grow in dry land, but still maintain the ecological type of swamp plants, it is appropriate to choose the humid zone planting. Taro is a fertilizer-loving crop, its bulb is formed in the subsoil layer, so you should choose organic matter-rich, deep loam or clay loam soil. Hydroponically it has requirements for water quality. Firstly the water should be clean and not contain impurities. Secondly, the water should be warm, and in winter it should be kept in water that has been left to dry and is at a temperature similar to room temperature.

Either water taro or dry taro like moist natural environmental conditions, dry taro growth period requires moist soil, especially leaf vigorous growth and bulb formation period, water demand is large, requiring increased watering or in the rows of grooves filled with shallow water. At the same time, pay attention to the early stages of bulb formation and ripening spraying ground fruit strong tilling, so that the underground fruit nutrient transportation conduit thicker, improve the ground fruit expansion vitality, smooth fruit surface, fruit type robust, quality improvement, to achieve a good yield. Water taro requires a certain water layer during the growth period, seedling water layer 3-5 cm. Leaf growth period to the water depth of 5-7 cm is good, 6-7 days before harvest to control watering and irrigation, in order to prevent the bulb contains too much water, intolerance of storage.
