After selecting the land, the soil 30cm should be turned deeply, and the ridge of the field should be heightened and strengthened to ensure that the height of the silt is about 20cm. Finally, about 2500 kg of mature manure or 300kg of mature stable manure should be sprinkled per mu, and finally turned deeply into the soil and placed in shallow water for later planting.

(3) Seedling raising method: before planting, dig some stout white underground stems, water stems or dormant buds during the growing period, and then insert them vertically into the soil according to the distance between rows and 50cm.

(2) Fertilizer requirements: water shield does not have high requirements for fertilizer. In general, when the leaves turn yellow or grow slowly in the field, some phosphate fertilizer can be applied properly. The specific amount and time of fertilizer application are determined according to the growth of water shield.
