Water chestnut is also known as "horseshoe" flesh can be eaten as a fruit, crisp and delicious, delicious and juicy. It can also be used as a medicinal material. It has many effects such as clearing heat and detoxifying, eliminating dampness and stopping phlegm. It has obvious therapeutic effect on patients with fever. So how is chufa planted? Today, Xiaobian will give you a brief introduction.

1. Selection of land

Water chestnut likes moderate temperature, high humidity but not cold-resistant, more suitable for planting in the bottom layer of solid, soft soil layer should be cultivated in about 22 cm. Because this not only allows water chestnut production and development, but also prevents its stem from drilling deeply, and its development size will be similar. It is beneficial to harvest and sales. If the soil is too viscous, it will affect normal growth and reduce sugar content.

2. Seedling

The specific time of seedling should be determined according to the time of transplanting. Early water chestnut starts one month to one and a half months before transplanting. Late water chestnut began to grow seedlings half a month to one month before transplanting. The bud should be selected to be robust and thick, with full edges, and disease-free and injury-free seeds. The seed should be arranged well, covered with straw, drenched twice a day, and planted with lateral buds.

3. ramets

Before planting, pull out the chestnut seedlings, wash the mud with water, and remove some small seedlings. This is because the probability of branching will decrease after this kind of seedling is planted. If ramets occur, the mother plant should be divided into about three groups. The stem is too long, cut off the growing part to prevent it from being broken. If it is a seedling with a seed, the bulb should be buried about 9cm deep in the soil. If the plant is divided, the root should be arranged and buried a few centimeters deep.

4. Fertilization

Water chestnut base fertilizer per mu should be applied about 40,000 kilograms of farm manure, calcium superphosphate about 5000 kilograms. The amount of topdressing applied during tillering and plant division period to promote the growth of water chestnut was mainly based on transplanting period and soil fertility. Early water chestnut mainly to base fertilizer and organic fertilizer, in transplanting half a month, flowering stage is applied once farm manure. However, the amount of fertilizer should not be excessive to avoid excessive growth of plants, causing pests and lodging. Late water chestnut should increase the amount of fertilizer and apply more quick-acting fertilizer.

5. Harvest

Harvesting usually lasts until the spring equinox of the following year. If the harvest is too early, the flesh is not sweet, the pericarp is thin, and it cannot be stored. The winter solstice is the sweetest and highest sugar stage of water chestnut flesh. Therefore, harvest at the beginning of winter solstice is the most appropriate. Drain the water in the ground the day before harvest, then strip off the upper layer of soil, dig out the soil and water chestnuts in the lower layer, and squeeze out the water chestnuts by hand.

The above is a simple introduction to how to grow water chestnuts. Water chestnuts are actually very good crops to grow. There is no great requirement for humidity and care, as long as more attention is paid to pests and diseases in the maintenance process. After all, pests and diseases are the pain of all crops. A carelessness may lead to a large reduction in production or even production.
