Planting method of "Underground Snow Pear" Water Chestnut (Horseshoe)

Water chestnut, also known as horseshoe, water chestnut, thorn turtle and so on, is a kind of fruit and a kind of vegetable, crisp and delicious. So, what is the planting method of water chestnut? Let's get to know it together.

1. Select the place

Water chestnut is not strict with soil and can adapt to all kinds of soil environment, but neutral and slightly acidic soil is the best choice. The planting site requires convenient drainage and irrigation, it is not suitable for continuous cropping of water chestnut, and it is best to rotate with other crops at intervals of 2-3 years. Reduce the incidence of diseases, but also reduce the impact of diseases on yield and quality.

2. Seed selection and seedling raising

The propagation method of water chestnut is to use bulbs for asexual reproduction. When sowing, select bulbs with undamaged epidermis, strong terminal buds and lateral buds, dark brown color and large bulbs. Generally, only 50 or 60 corms per mu are needed. Sowing time is at the end of March or early April, before Ching Ming Festival as far as possible. Before sowing, soak the bulbs with 50% carbendazim wettable powder for one day. After disinfection, put the bulbs into the seedling bed. When drained, the tip of the bud goes up, and after the row, it is covered with a layer of fine soil, and the seedbed is watered to keep the seedbed moist.

3. False planting

When the young buds grow to 10-15cm in the seedling bed, and there are 3-4 lateral buds, the pseudo-planting can be carried out, usually at the end of April or early May. The early rice field can be selected for pseudo-planting, and the soil preparation is applied before pseudo-planting. The manure 1000kg, ammonium bicarbonate 25kg and compound fertilizer 25kg are applied per mu, and the germinated water chestnuts are pulled out and planted in the paddy field, keeping the plant row spacing 40 × 50cm, keeping the water depth 1-2cm in the early stage, and deepening to 2-3cm in the later stage. Strengthen the fertilizer and water management, when the seedling height 40cm can be planted.

4. Colonization

Soil preparation and fertilization are also required during planting, such as deep ploughing 20cm, fine raking, applying sufficient base fertilizer, pulling out the pseudo-planted seedlings, digging out the seedlings with bulbs when pulling seedlings, and removing the male water chestnut seedlings with clusters of leafy stems. If the seedlings are too high, cut off a section of the leafy stem tip to avoid being affected by the wind after planting, soak the seedling roots with 25% carbendazim wet powder for 1 hour. After smearing some rooting powder, the planting depth is 8-12cm, so that the root system is in perfect contact with the soil, planting about 4000 plants per mu and keeping the row spacing 60 × 30cm.

5. Field management

Strengthen the management of fertilizer and water, adopt the method of transplanting in shallow water and living trees in deep water, planting in shallow water, the water level is 2-3cm, deepen the water level to 5-9cm after planting, lower the water level to 2-3cm after survival, keep the water level at 8-10cm in the maturing period, stop irrigation when the corm is mature, and keep the soil moist. Fertilization is mainly based on base fertilizer, supplemented by topdressing, mainly nitrogen, phosphorus and potassium fertilizer, nitrogen fertilizer in the early stage and phosphorus and potassium fertilizer in the later stage, which can be combined with intermediate ploughing and weeding to remove weeds so as not to seize nutrients with plants. when weeding, diseased or weak seedlings can also be pulled out directly.

The above is the planting method of water chestnut, I hope it can help you!
