2. Choose a fertile clay loam field. The lotus root's product organs are formed in the subterranean soil. Therefore, paddy fields that grow shallow water can store moisture, are rich in organic matter, and have thick silt layers. The fertile clay loam is most suitable.

3, rational close planting. The planting density of lotus root is closely related to ripening period and yield. It is suitable for dense planting and has the effect of early maturity and yield increase. The density of general early-maturing varieties is: row spacing is 2 meters and the distance between holes is 0.7 meters. Late-maturing varieties should be sparsely planted, with a density of 2-2.5 meters spacing and a 1-meter spacing.

4, base fertilizer and top-dressing. The lotus root grows for a long period of time and requires more fertilizer. The general principle of applying shallow water to earthworms is equal weight between base fertilizer and top dressing. In general, 1500-2500 kg of livestock manure or manure is used as base fertilizer per mu. Precocious pods generally cover 1500-2000 kg of manure per mu. The top dressing is divided into three parts, focusing on the early stage of scarring.

5. Scientifically regulate water levels. The general principle of the shallow water layer management is shallow, medium depth, and shallow. The water layer in the bud growth phase should be shallow, preferably 4-7 cm, and the water layer in the vigorous growth period of stems and leaves should be deeper, preferably 12-15 cm. The water layer should be shallow during the crusting season, preferably 4-7 cm.

6, diligently turn shoots, timely weeding. In the vigorous growth period of lotus root stems and leaves, the whip grows rapidly. When the leaf leaves are about 1 meter away from the field side, in order to prevent the shoot tip from passing through the field ridge, the tip of the field plough is pulled to the field every 2-3 days. The shoots are very tender, and the soil should be pulled out along with the shoots to prevent breakage and swaying. It is better to do it at noon when turning. In the early stage of shallow water bream growth, there are more weeds, which have a greater impact on the growth of lotus root. Weeding should be done in time, and weeding should be combined with manual weeding and chemical weeding.

7, timely harvest. After the end of the leaves of the lotus root, the leaves of the terminating leaves show a reddish color, and when the edges of the basal leaves begin to yellow, the pods have fully matured. You can dig up the market.
