Horseshoe planting methods: land selection, seedling, timely planting, fertilizer management.

1, land selection

Horseshoes like fertile and loose, well-lit paddy fields, and to ensure that the paddy fields should have sufficient water, convenient drainage and irrigation. After selecting a good paddy field, apply appropriate amount of calcium superphosphate and potassium chloride as base fertilizer to maintain soil fertility, and then use nail harrow to mix it with soil evenly, and also loosen the soil.

2, seedling

Horseshoes use bulbs for propagation, before propagation, select a large, full, unbroken, smooth epidermis, buds and thick bulbs as seedling seeds. Before planting, the seed can be dipped in disinfectant and sterilizing agent for 10-24 hours, fished out and dried, reasonably control the spacing between plants and rows, and press the buds upward into the silt.

3, timely planting

General early water horseshoes in the seedling age of 45-70 days planting, and late water in the seedling age of one month or so planting, planting to control the spacing of 30 × 60cm. main stem clumps of seedlings and seedlings can be used as a planting seedling, the depth of the planting in order to plant a stable appropriate, planting if the seedlings are too high, then cut off part of the tip, leaving only a portion of the tip of the planting. The top of the plant is too high, only 25-30cm can be left.

4, fertilizer management

Horseshoe fertilizer management is extremely important, first of all, to the management of the water layer, horseshoe in the early stage of the water level should be controlled in the 2-3cm, with its gradual growth, deepen the water level to 7-10cm. in the planting of water to 6-8cm, to the knotting period, it is necessary to lower the water level to 3-5cm, winter to keep 1-2cm shallow water. Keep a shallow water level of 1-2cm over winter.
