a. Release water for spot sowing. Put the pond water dry or keep the shallow water level, dig holes at a distance of 2.5 meters square, sow 2-3 seeds in each hole, cover the soil with 1-1.5 cm, and irrigate to the proper water level after sowing, so that the seedlings emerge neatly.
b. Mud dough spot sowing. The water level is deeper than 1 m in the lake area, the water level is not easy to lower or due to the lack of water, it is difficult to irrigate after releasing water because the water depth is not easy to sow, the seeds are easy to drift after sowing. Can use mud group spot sowing. Then use wet clay will be 3-4 seeds wrapped into a ball, according to the line plant distance of about 2.5 meters square, the clay is grouped one by one on the near water surface gently into the water. The thin density of planting should vary according to the fatness of the lake and pond mud.
c. Bamboo tube seeding. Use the long bamboo tube hit through, according to the row plant spacing of 2.5 meters, insert the bamboo tube into the mud, put 4-5 seeds from the upper mouth, the seeds sink to the bottom, then use a thin stick, inserted into the tube, stirred in the mud, so that the seeds mixed into the mud.
d. After sowing, the water level is maintained at 60-100 cm, and seedlings can emerge in late April. Generally, after one year of planting, each year there are mature seeds naturally scattered in the water, and the next year will be able to germinate and grow naturally, generally do not need to sow again.
