Cultivation techniques
It is a class of water spinach can live in both dryland and amphibious plants can live in the paddy field, but still more water when the growth is strong, the most suitable for planting in the fertilization of the paddy field or near the barn of the field of frequent drainage of manure water. It can also be planted in fertile drylands, and planting in drylands promotes more seeds, so it can be cultivated in drylands when saving seeds.
Ip water spinach has a strong adaptability to the soil, both fertilizer, and stain resistance, but also has a certain degree of barrenness, but under artificial cultivation conditions, in order to achieve high yield, to organic matter-rich clay loam or loamy soil cultivation for the most suitable. Water spinach is not drought tolerant.
Ipomoea seeds begin to germinate at about 15 ℃, the growth temperature of 20 to 35 ℃, the seed vines axillary buds sprouting at the beginning of the temperature of 30 ℃ or more, sprouting fast.
