According to Compendium of Materia Medica, Yanghe not only can be eaten as a vegetable, but also has the effects of promoting blood circulation, regulating menstruation, relieving cough and resolving phlegm, relieving swelling and detoxifying, promoting digestion and invigorating stomach. It has special effects on treating constipation and diabetes, and has high medicinal value.
Yangyang Heta contains a variety of amino acids, protein and rich cellulose. The cellulose contained in it is also a polysaccharide nutrient and will not produce heat energy. If eaten regularly, it is beneficial to keep the digestive tract unobstructed and maintain normal defecation function. Can be used for treating constipation, promoting digestion and invigorating stomach, and has special effects on diabetes. Therefore, Yanghe is a pure natural dietary fiber food with the same origin of medicine and food.
Planting techniques:
1, choose the suitable planting environment. According to the survey, Yanghe River is fertile, loose, moist and cool, and it is more resistant to shade, high temperature and strong light. Therefore, it is best to choose two high mountain areas with abundant rainfall, plenty of clouds, cool summer and high soil organic matter content for planting lotus in a large area. Large-scale planting of lotus in low mountainous areas must be interplanted with trees or tall crops, otherwise it will not be easy to succeed.
2. Apply base fertilizer and farmyard manure again. Yang He planted it for a year and benefited for many years. In order to obtain high yield and high efficiency, it is necessary to apply sufficient base fertilizer and farmyard manure according to the growth demand of Yanghe River. Generally, 4000-5000 kg of soil miscellaneous manure or manure and 50 kg of compound fertilizer (or 40 kg of calcium superphosphate and 0/0 kg of potassium sulfate/kloc) are applied at the bottom of each mu. It is best to plough deeply and apply base fertilizer, and the flat land can also be flattened and then ploughed deeply. It is best to open a ditch with a width of 60-80 cm and a depth of 40-50 cm along the horizontal line on the sloping land in mountainous areas, spread base fertilizer in the ditch, then backfill the topsoil and transplant the lotus.
3. Propagation by ramets and reasonable close planting. Lotus mainly propagates by chopping branches. Pay attention to 2-3 complete buds per bud. It can be transplanted in September 9- 10/0 in autumn or March-April in spring, with a large row spacing of 60 cm, a small row spacing of 30 cm and a planting area of about 3300 mu.
4. Post-planting management and harvesting. Water the root after planting. In summer, the temperature is high and the light is strong in the low mountains, so proper shading must be considered in the first year of planting. After transplanting, after seedling emergence every spring, combined with intertillage weeding, dilute manure water is used to raise seedlings to promote the robust and consistent growth of seedlings. Before the buds are unearthed every year, the "bud-promoting" fertilizer should be applied again to promote bud hypertrophy and improve quality and yield. Before overwintering, 2000-3000 kg of farm manure and 50 kg of compound fertilizer (or 40 kg of calcium superphosphate and potassium sulfate 10 kg) should be applied with deep tillage to ensure the safe overwintering of plants and increase the annual output in the future.
When the lotus is harvested, it should be broken before the bud blooms after being unearthed. Early harvest has good quality but low yield, and late harvest makes the fiber thicker and the variety worse. Generally, you can harvest 1 1,000-11,500 kilograms of buds per mu, with a market price of 2-3 yuan per kilogram and an output value of about 3,000 yuan per mu. Because planting lotus can be harvested for many years in a year, except for the large investment in the first year and the low investment in the second year, the income is considerable. Rootstock of lotus root
After 3-4 years of continuous harvesting, some seeds should be dug out and properly divided, on the one hand, to prevent failure due to excessive density, on the other hand, the dug seeds can be used to expand the area.
It is worth noting that there are few pests and diseases in sporadic planting, but in large-scale continuous cropping, the diseases are obviously aggravated after several years of continuous planting. Therefore, after the abnormal death of plant leaves is found, the roots should be irrigated with fungicides such as Tobuzin, Dixon and Zhuanyiling immediately, and the leaves should be protected by spraying "green milk copper".
