Lotus root is a perennial herbaceous aquatic plant and is an important summer vegetable. The adoption of facilities for cultivation can promote lotus roots to raise the market in the morning and increase economic efficiency. The cultivation techniques are introduced as follows: First, choose good breeds. Use early-maturing, high-yield shallow lotus root varieties. It requires no injury, no sickness, good seeding, large individuals, complete bread, full tail tip, complete apical buds and lateral buds, and thick, full-bodied pods for pods, and seeks uniformity in size. Second, fertilize the whole field. The fertile soil, deep mud layer, and convenient drainage and irrigation are the best choices. In the 15 days before planting, Mushi applied 2000-3000 kg of organic fertilizer, 150 kg of cake fertilizer, 70 kg of superphosphate, and 80 kg of quick lime. After fertilization, deep plowing, thinning, flattening paddy field, and maintaining a 3-5 cm deep water layer. three. Planted germination. 1. Pregermination: Since the temperature in early spring is low, and when cold waves invade, the species can be picked up and germinated. The germination method is: The pods are piled up and piled up to a height of about one meter. The stack is covered with dry straw. Frequently sprinkle water on the seedlings to maintain a certain temperature and humidity in the heap. When the species grows out of the top buds, it is planted on sunny mornings. 2. Planting density: Early cultivation generally requires a higher density of rowworms. The amount per mu is 250-300 kilograms, and the row spacing is 0.81.8 meters. Mu requires 300-400 buds. 3. Planting methods: In the middle and early March, the rows are planted according to the above row spacing. Each row between the row and row should be arranged in a plum shape. The field side buds are headed inwards. The direction of the other rows of buds should also be the same. When planting, the bud head is inserted into the mud and the tail tip is curled Out of the water. 4. Arch cover film: timely cover film after planting. A bamboo frame arch with a length of 3 meters and a width of 3 centimeters is used, and the amount of mu is about 300 pieces. The arch is 2.2 meters wide, the arch is 40 centimeters high and covered with agricultural film. Fourth, field management 1. Pre-management: This period is mainly to promote the formation and growth of floating leaves. To manage the water, it is better to keep the depth of 5 to 10 centimeters of water and keep the soil in a thin state. When the cold wave comes, it is necessary to store water and keep warm in advance. When it's sunny and hot, pay attention to the air ventilation in the shed to prevent burning the lotus leaf. After mid-to-late April, when the temperature stabilizes at about 20°C and the lotus leaf is full of lotus leaves, the arch can be removed and the arches can be flooded to 10-15 cm, and 1,000 kg of livestock manure and urea can be applied. kg. 2. Management in the middle and late period: Generally, in the middle and late of May, the grass will be torn from the grass one by one. After the grass is pulled, in order to evenly distribute the lotus root in the field, the growth direction of the lotus whip should be adjusted in time, and the growth of the lotus whip should be prevented. In this period, 20 kg of compound fertilizer and 10 kg of urea should also be planted in Mu. 3. Do a good job in disease prevention and control. It is mainly due to the soft rot of lotus leaf. It is required to keep the water quality clean. The diseased leaves should be removed in time and sprayed with 70% thiophanate-methyl 800-1000 times every 10 days. V. Grazing. In late June, when the lotus root grows in 3 knots, it can be harvested in batches, which is about 20 days earlier than conventional cultivation. Take care not to damage other lotus roots when harvesting. Disclaimer: Some articles in this website have been transferred from the Internet.
