Horseshoe grows in ponds or paddy fields.

1. Horseshoe grows in ponds or rice paddies, and it reproduces asexually using bulbs, also known as fruiting balls. Like warmth and love of moisture, it is afraid of freezing and is suitable for growth in loamy soil with loose topsoil and firm subsoil.

2, cultivation requires 20-25cm of tillage, which is conducive to the growth and development of bulbs, without the need for deep drilling of bulbs. Individual development of uniform size and neat, but also conducive to digging and harvesting. The topsoil is too sticky, not conducive to bulb expansion.

There is too much humus, and the sugar content of the bulbs is reduced, and the sweetness is poor. Suitable for shallow water growth. In terms of nutritional requirements, it needs less nitrogen fertilizer and more phosphorus fertilizer, and throughout the growth period, it needs sufficient light.

The horseshoe is the alias of water chestnut, it needs high temperature and long sunshine in the pre-growth period, such as sprouting temperature of 15-20 ℃, tillering (grass and other plants below ground or close to the ground at the branching that occurs) branching optimal temperature of 25-30 ℃, and in the later stages of growth, shorten the number of hours of light (suitable for less than 13 hours) can promote the formation of the bulb, lower temperatures (20-25 ℃) are also conducive to bulb expansion.

The soil should be sandy loam or humus loam with shallow layer and pH 6-7. The growing period of water chestnut is 140-200 days. The bulb can overwinter in the soil, and in the following spring to the terminal bud draws an inconspicuous shortened stem, the base of the stem node downward to produce slender fibrous roots, into the soil about 20-30 cm, upward to produce filamentous stems (tubular stems), and continue to tiller, the formation of the mother plant.
