Lotus Root High Yield Management
Because of the specific growth and management methods of lotus root, the planting area in the northern area is relatively small, and some old planting areas have been abandoned due to various reasons. The reason for this is mostly the backwardness of plant management techniques. Scientific management can win high productivity and gain high efficiency.

On the one hand, preparatory work for planting should be done well. Ponds should be set around the pond to avoid tall trees and other shades to avoid affecting photosynthesis.
The base fertilizer is mainly farmyard manure, and chemical fertilizer is used in conjunction with the application. General Mu Shi decomposed livestock manure 2000 kg, 500 kg of cake fertilizer or human waste, ammonium bicarbonate 150 kg, superphosphate 150 kg, potassium sulfate 10 kg. Farmyard fertilizers must be fermented and sterilized to prevent pathogens from entering the field. The pool pool must be more than 40 cm above the ground and maintain a certain surface water temperature, which is beneficial to early harvest, festivals and high yields. Commercial field selection of the main section of the festival, hypertrophy, about 500 kilograms of seed pods, should not be too thin or too dense, self-retained farming can be properly planted with the selected defective, usually 1 meter spacing, spacing 1.5 meters. Before entering the fields, the strains suspected of being sick should be discarded without using them to prevent the spread of germs. If necessary, fungicides such as carbendazim and chlorothalonil should be used. It is known that the land with bacteria should be replaced with other crops to prevent chance.
On the other hand, during the growing season, fertilizer and water management will be strengthened. When the lotus leaves do not grow over the fields, Mushi DAP 20-30 kg, to promote growth. At the beginning of the lotus, Urea 15-30 kg of urea was applied to accelerate the differentiation of stem segments in lotus roots. Lotus Mushi urea 20-30 kg, 10-20 kg of potassium fertilizer, promote lotus root stem enlargement. In the later stage, top-dressing is appropriately performed to avoid the uneven growth of stem sections of lotus root due to defertilization, short section length, and low yield. Avoid applying chlorine and nitrate nitrogen fertilizers to avoid deterioration of quality and taste. In the rainy season, water injection should be minimized and nitrogen fertilizer should be reduced. If the water temperature is low for a long time, it will affect the growth of underground stems.
During the winter, the freeze protection work in the field will be carried out. When the upper part of the field is dry, the stems and leaves will be removed and covered with corn stalks. In particular, the land with a soil layer thickness of less than 30 cm must be thickly covered to avoid freezing damage. Plastic film can also be used to cover the field, pay attention to the interface more pressure soil, to ensure that the wind can not blow open.
