top dressing. Can be topped 2-3 times. The first time when the 1-2 leaves are erected, the second time can be before the seal line and the third time when the rear leaf appears. For every 667 square meters (mu), the first application of manure 2000-4000 kg or urea 15 kg, the second application of compound fertilizer 20-25 kg, the third application of 10-15 kg of urea, early maturing growers can only apply twice top dressing.
Weeding soil. Before removing the line, weeds must be removed at any time. When 1-2 pieces of lotus leaf are grown, fertilization can be done by hand or by loosening the soil around the lotus seed to facilitate the growth of lotus whip. When loosening the soil, it should be prevented from breaking off the stems.
Turn your head. In order to distribute the Lianbian equably in the middle of the field, and to avoid the insertion of field ridges, it is necessary to check the growth direction of the whip at any time. Move to the lean place. When turning the hoe, first open the soil in the first and second sections of the lotus root, reveal the bud head and the lotus whip, and then lift the lotus whip by hand to adjust the direction, bury it in the soil, and do not pull hard to prevent the lotus whip from breaking. It is better to use sunny afternoons to change your time.
Water management. General Putian can not cut off water. The depth of the water layer should be controlled according to the principles of early shallow, medium-deep, and late periods. In the middle of growth, the temperature is high, and the stems are also high at that time, and the water depth can reach more than 20 cm. After the dead load, if the seedlings are kept in the following year, a certain depth of water layer should be maintained to prevent the soil from cracking and freezing the underground stems in the cold winter, and at the same time, the dry earth blocks can be avoided from becoming hard and difficult to be excavated.
