The latest course of planting techniques and methods of water chestnut

Water chestnut, also known as horseshoe, water chestnut, because its appearance and effect are similar to chestnut, but also grow in the soil, so also called ground chestnut, it is crisp and sweet, we have all eaten, both as a fruit raw food, but also as a vegetable. So do you know how it is planted? Let's take a look at the pro-farm network.

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 land requires convenient drainage and irrigation, and it is not suitable for continuous cropping. It is best to rotate with other crops at intervals of 2-3 years. Reduce the incidence of diseases and reduce the impact of diseases on yield and quality.

2. Seed selection and seedling raising

The propagation method of water chestnut is the asexual propagation of bulbs. When sowing, the bulbs with no damage to the epidermis, strong terminal buds and lateral buds, dark brown color and large bulbs are selected as seeds. Generally, only 50-60 per mu and bulbs are needed to ensure that it is low in March or early April, as far as possible in front of Ching Ming Festival. Before sowing, soak in a 600-fold solution of 50% carbendazim wettable powder for one day for disinfection. After disinfection, put the bulb into the seedbed, put the bud tip up, and cover a layer of fine soil after the row. Keep the seedbed moist in watering.

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 at the end of April or early May, and the early rice field can be selected for low false planting. Soil preparation and fertilization were applied before pseudo-planting, and manure 1000kg, ammonium bicarbonate 25kg and compound fertilizer 25kg were applied per mu. When pseudo-planting, the germinated water chestnut was pulled out and planted in the paddy field, keeping the row spacing 40 × 50cm, keeping the water depth 1-2cm in the early stage, deepening to 2-3cm in the later stage, strengthening the fertilizer and water management, and planting when the seedling height was 40cm.

4. Colonization

The same soil preparation and fertilization during planting requires deep ploughing of 20cm, fine raking, applying sufficient basic fertilizer, pulling out the pseudo-planted seedlings, and digging out the seedlings with bulbs when pulling out the seedlings. Remove the male water chestnut seedlings with clusters of leafy stems. If the seedlings are too high, the tip of the leafy stem can be cut off to avoid being affected by the wind after planting. After washing the seedling roots, soaking them with 25% carbendazim wettable powder for 1 hour, and then smearing some rooting powder, the planting depth is 8-12cm, so that the roots are in perfect contact with the soil, about 4000 plants per mu are planted, and the plant spacing is 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 water chestnut planting technology brought by the pro-agricultural network. I hope it can help you. If you want to know more about water chestnut plants, please pay attention to the pro-agricultural network.
