The nutrition of water chestnut is rich, the water content is very high, the content of vitamins and minerals is also many, but also with protein, dietary fiber, carotene, iron, calcium, phosphorus and sugar and carbohydrates, but the caloric value is not high. Water chestnut is generally in the water chestnut winter, spring on sale, in the choice of water chestnut, to pick the water chestnut root at the whole flat, do not have to choose the root of the uneven, in addition to the color of reddish water chestnut is more tender, the color of the water chestnut blackened water chestnut is more old.

1, seedling field prepared in advance: to how to plant water chestnut yield, the first seedling field is a prerequisite. Because all plant growth can not be separated from the soil layer of nutrients, and the horseshoe is very like rich and loose, sunny, loose subsoil, subsoil firm seedling field, and to ensure that the rice paddy water resources are plentiful, watering and irrigation is convenient, and in accordance with the 1 acre application of phosphorus fertilizer, potassium chloride solution is appropriate, and ultimately to carry out the solution of turning the soil with a rake.

2, pre-seedling: then lay a layer of straw on the floor. Sort the seeds face upward on the straw, the top side of another layer of straw laying rolls, watering once a day late in the morning and early in the morning. About two weeks later, when the buds are 3cm long around the case, you can put the seedlings into the rice field to carry out side-by-side planting, generally to the March to April period of pre-seedling, and it is best to early pre-seedling, so that the middle and late production is relatively large.

3, seedling management methods: to the case of sprouting and rooting links, because the horseshoe is a hydrobiological crop, it is best to maintain a shallow water layer of 3 ~ 5cm in the seedling period, to be two weeks after the gradual emergence of the tree, and then put the rotting seedlings and weeds into the seedling field, so that is conducive to the growth and development of the horse's hooves. At this time it is best to add a car urea solution to promote the early pumping of horseshoe fibers.

4, fertilizer management methods: If you ensure that the horseshoe yield, it is necessary to effectively increase the fertilizer to ensure that the horseshoe nutrient supplement. It is best to use organic fertilizers as the leading, in the process of the growth period can increase the organic fertilizer water solution, that will promote the growth and development of the stem and rhizome. In the case of the developmental stage, it is best to add organic fertilizers on a regular basis and make sure that the amount of fertilizer applied is not suitable to be too much in order to prevent the plant from playing with vigorous growth. In the later stages of the process can be sprayed at weekly intervals with a mixture of mannitol, urea solution, potassium dihydrogen phosphate appropriate on it.
