How to grow chicken head fruit

Chicken head fruit is the mature kernel of Euryale fruit, and its fruit is similar to "chicken head", so it gets its name. It is a natural and pollution-free green food, which is widely planted in the south of our country. So how to grow chicken heads?

The chicken head fruit is adaptable and can grow in ponds, swamps, lakes, reservoirs and low-lying paddy fields. Chicken heads must grow during the frost-free period. Like warm and humid, sunny, fertilizer-resistant, not resistant to frost and drought. Seeds above 15 ℃ began to sprout. 20 ℃ to 30 ℃ was the most suitable for vegetative growth and flowering and fruiting. The growth stopped when it was lower than 15 ℃. Fruits and seeds can not be fully matured, and the soil is slightly acidic to neutral. The whole growth and development process of chicken head fruit needs water, but there are certain requirements for water level, generally 10 cm to 20 cm in seedling stage, and then with the growth of the plant, the water depth gradually increases to 70 cm to 90 cm, the deepest should not exceed 120 cm. When the water level is adjusted, it should not rise and fall sharply.

During the period of growth and development, equal emphasis should be placed on nitrogen, phosphorus and potassium. In particular, more phosphorus and potassium fertilizer is needed in the flowering and fruiting period. Chicken head fruit can be cultivated by seed direct seeding, or by seedling and transplanting. Generally, due to the extensive cultivation of direct seeding, the emergence rate and yield are relatively low. Although the cultivation method of seedling transplanting is relatively troublesome, the yield is higher. Therefore, seedling transplanting is usually used in production.

Chicken head fruit is cultivated in a large area in the Huaihe River Basin, the Yangtze River Basin and the south of the Yangtze River Basin, which is one of the important ways to adjust the agricultural structure and increase the income of farmers.
