Lotus root cultivation can be managed by referring to the following methods:
For topdressing lotus root, apply fertilizer 2-3 times. The first time is when 1-2 standing leaves have grown, the second time can be before the rows close, and the third time is when the rear ridge leaves appear. Per 667 sq m (mu), for the first application use 2000-4000 kg of manure or 15 kg of urea, for the second application use 20-25 kg of compound fertilizer, and for the third application use 10-15 kg of urea. Those growing early-maturing varieties may apply topdressing only twice.
Weeding and loosening the soil: Before the rows close, remove weeds at any time. When there are 1-2 standing leaves, after fertilizing, loosen the soil around the lotus root seeds with your hands or a hoe to promote the growth of the lotus rhizome. When loosening the soil and weeding, prevent breaking the lotus stems.
Turning the lotus root heads: In order to make the lotus rhizomes distribute evenly in the field and avoid inserting into the field ridges, check the growth direction of the lotus rhizomes at any time. Move them toward sparse areas. When turning the lotus root heads, first dig away the soil from the first one or two nodes in front of the lotus root to expose the bud tips and lotus rhizomes, then use your hands to lift the lotus rhizomes and adjust their direction, and bury them in the soil. Do not pull hard, to prevent breaking the lotus rhizomes. The best time to turn the lotus root heads is on a sunny afternoon.
Water level management: Generally, a lotus root field must not be cut off from water. The water depth should be controlled according to the principle of shallow in the early stage, deep in the middle stage, and shallow again in the later stage. During the middle of growth, when the temperature is high and the lotus stems are also tall at that time, the water depth can reach more than 20 cm. After the lotus withers, if keeping seeds until the next year, a certain depth of water should be maintained to prevent the soil from drying and cracking and to avoid freezing damage to the underground stems in cold winter, and at the same time to avoid the soil blocks becoming hard after the field dries, making them difficult to dig up.
