Detailed Explanation of Water Chestnut Planting Methods and Cultivation Techniques
The water chestnut, also known as the Chinese water chestnut, produces fruit that can be eaten directly as a fruit; its seedlings, roots, and fruit can all be used as medicine, offering excellent healthcare benefits, and it is a food loved by many people. Although we know of it, do you know how it is actually grown? Follow along with the editor below to see the detailed introduction.
1. Land Selection
To grow water chestnuts well, land selection is extremely important. Water chestnuts prefer fertile, loose paddy fields with ample sunlight, and the paddy field must have a sufficient water source with convenient irrigation and drainage. After selecting a good paddy field, apply an appropriate amount of superphosphate and potassium chloride as base fertilizer to maintain soil fertility, then use a rake to mix it evenly with the soil while also loosening the soil.
2. Raising Seedlings
Water chestnuts are propagated using corms. Before propagation, select corms that are large, plump and undamaged, with smooth skin and thick sturdy sprouts, to use as seedling seed. Before planting, the seed can be soaked in a disinfecting and sterilizing agent for 10-24 hours, then removed and dried. Reasonably control the plant and row spacing, and press the sprouts upward into the mud. After sowing, cover with rice straw or a straw mat to retain moisture and fertilizer and promote sprouting. After sowing, water frequently to keep the soil moist; moreover, water carefully so as not to wash away the soil on the corms. After the seedlings emerge, gradually uncover the straw mat and/or rice straw so the seedlings can adapt to the high-temperature and strong-light environment.
3. Timely Transplanting
Generally, early-water water chestnuts are transplanted at a seedling age of 45-70 days, while late-water ones are transplanted at a seedling age of about one month. When transplanting, control the plant and row spacing at 30×60cm. Main-stem clump seedlings and tiller seedlings can both be used as transplanting seedlings. The transplanting depth should be just enough to plant them firmly. If the seedlings are too tall when transplanting, cut off part of the tips, leaving only 25-30cm, in order to avoid breaking due to excessive height or lodging caused by wind.
4. Fertilizer and Water Management
Fertilizer and water management for water chestnuts is extremely important. First is water level management: for early-water water chestnuts, the water level should be controlled at 2-3cm in the initial stage, and as they gradually grow, deepen the water level to 7-10cm. For late-water water chestnuts, after transplanting, irrigate to 6-8cm, and at the corm-forming stage, lower the water level to 3-5cm; in winter, maintain a shallow water level of 1-2cm for overwintering. During the growth period, apply more chemical fertilizer dissolved in water to promote the growth of the water chestnut's rhizome. In the later growth stage, apply organic fertilizer irregularly, but not too much, to avoid excessive vegetative growth of the plants.
