Lotus roots are no strangers, whether it is stir-fried, soup, cold salad, and marinated are popular with everyone. Lotus root can also be said to be the healthiest, green food. It does not require spraying pesticides, so don't worry about pesticide residues. Lotus root is a rhizome of the lotus family, suitable for growing in the hot and rainy season. Lotus roots are more tenacious and easy to grow. The most important thing in the process of planting lotus root is fertilization, which is based on farmyard manure and other basic fertilizers. Of course, there are some tricks in planting lotus roots in terms of variety selection and planting management. The selection should not be too rigid. According to the actual situation of the planting area, you can choose the corresponding variety. You can go to the farmer's shop and other farmers who have the Qiangtang to consult, or you can get information from the merchants in the market. Generally, when selecting seeds, choose a variety that is full, fat, complete, and fine. The cultivation of lotus roots is mostly carried out by asexual reproduction, which preserves the good genes of the mother and shortens the growth period. Of course, it can also be directly planted with lotus seeds, but the lotus roots grown are more variability and grow more slowly. The organic acid-rich weakly acidic or neutral clay loam is more conducive to the growth and development of lotus root. When the lotus root is planted, the hoe can be deep into the mud about 250px, and then the section is slightly tilted on the water surface, so that more sunlight can be accepted, and the temperature can be increased to promote germination. When planting, remember that the muddy water should not be poured into the pupil, which will cause the cockroach to rot. The row spacing of lotus roots is controlled at about one and a half meters. The water in the ponds should increase first and then decrease with the growth period of lotus roots. After the growth period, the water level will be shallow and promote the maturity of the alfalfa. The waxy substance on the surface of the lotus flower effectively reduces the occurrence of pests and diseases of lotus root. However, lotus root fertilization, shallow water and heavy fertilizer, especially the use of organic fertilizers such as farmyard manure can promote the growth of lotus root. When lotus roots are harvested, the leaves are removed first, which can better remove rust spots, and of course prevent decay. If Qiangtang is used for long-term operation, it is important to note that it is possible to save a small amount of money. Pest control of lotus root Lotus leaf blight The damaged lotus leaf is yellowed and withered, affecting the growth of lotus root, resulting in reduced yield. Prevention: Keep the fields clean and prevent oil from contaminating the fields. Sewage, soapy water can also cause the leaves to wither and die. Lotus root is very sensitive to herbicides. Must not apply herbicides in Putian. Lotus root disease Symptoms can be expressed on the lotus leaf and the underground rhizome after the damage, and large polygons are formed on the leaves to the irregular brown spots. The roots of the rhizome produce dark brown anthrax streaks. Prevention and control: Select resistant varieties and timely control aphids (transfer media). At the beginning of the disease, spray 1.5% of the phytopathogenic emulsion 1000 times. Lotus root black spot Lotus root black spot disease (also known as brown spot disease, leaf spot disease), the initial needle-like yellow-brown small spots, the whole leaf is covered with lesions in the late stage, causing the half-leaf or whole leaves to dry up. Prevention and control: increase the application of phosphorus and potassium fertilizer to avoid partial application of nitrogen fertilizer. In the winter, the diseased leaves were completely removed and burned intensively. In the early stage of the disease, the diseased leaves were removed and sprayed. Commonly used 70% Jiato 1000 times liquid or 65% Daisen zinc 600 times liquid. Or 1:1: 166-200 times Bordeaux mixture, spray once every 10 days, a total of 2-3 times. Lotus root disease (藕瘟) The initial leaves are pale green, dry from the edge, and the whole leaves are curled and dry, the top of the handle is curved and dry, and the whole field is yellow and burnt. Prevention and control: 2-3 years of rotation in heavy disease fields. Commonly used 70% methyl thiophanate 1000 times solution or 75% chlorothalonil 800 times solution spray stagnation, cover the agricultural film sealed for 24 hours, dry and plant. Before the planting of the field, it was deep-turned and applied 100 kg of lime. At the time of onset, 75% chlorothalonil 0.5 kg and dry soil 30 kg can be mixed and sprinkled into shallow water fields. Because the pathogen of lotus root spoilage disease is in the soil part of the stem, it is necessary to spray the lower part of the stem to prevent the disease, leaving only 3-5 cm of water, and continuous control twice in 3-5 days. Lotus root is also a food that can also be used as medicine. It has the effects of stopping bleeding and dispersing blood stasis, benefiting blood and muscle. You can say that the whole body is a treasure, whether it is its root or stem or leaf, it has its medicinal value. And lotus root is easier to plant and manage well, but pay attention to fertilization management when planting lotus root.
