To achieve a high-yield cultivation of red vetch, there are a few key steps that can be followed:
1.Choose the right soil: Red vetch prefers to grow in deep, fertile, loose, and breathable soils. Therefore, it is necessary to choose a good soil before planting and make appropriate improvements to ensure the normal growth and yield of red vetch. Soil can be improved by increasing organic fertilizer, loosening soil, drainage, etc.
2.Selection of high-quality seedlings: Choosing seedlings that are free of diseases and pests, have developed root systems, and are full of tubers can improve the success rate and yield of planting. It can be obtained by purchasing high-quality seedlings, self-propagating seedlings, and retaining seed potatoes.
3.Timely planting: The planting time of red lotus is generally carried out when the temperature reaches about 20, and the most suitable planting temperature is 18-22. Planting at the right temperature can promote the growth and development of red vetch and increase yield.
4.Reasonable dense planting: The planting density of red lotus should be moderate, not too dense or too thin. Reasonable dense planting can improve the utilization rate of photosynthesis and increase the yield. Generally, it is advisable to plant 3000-4000 plants per mu.
5.Watering and fertilizing: Sufficient water and fertilizer are needed during the growth of red vetch. During the planting process, it is necessary to water at the right time, keep the soil moist, and apply fertilizer reasonably according to the growth needs of red roots. Organic fertilizers, compound fertilizers and other fertilizers can be used to ensure the nutrients required for the growth of red roots.
6.Pest control: In the process of growth, we should pay attention to the prevention and control of pests and diseases, find and deal with pests and diseases in time, and ensure the normal growth of red vetch. Common pests and diseases include sweet potato blast, ground tiger, needleworm, etc., which can be controlled by biological control, chemical control, physical control and other methods.
7.Harvest at the right time: When the red lotus is ripe, it should be harvested in time. Harvesting too early can affect yields, while harvesting too late can cause chunks to break and rot. By observing the color and growth of the potato skin, the harvest time is determined.
The high-yield planting of red lotus needs to comprehensively consider the soil, seedlings, planting time, management and other aspects, and realize the high-yield planting of red lotus through scientific management and technical means. At the same time, we should also pay attention to environmental protection and sustainable development, adopt green and environmentally friendly planting methods, improve the yield and quality of red roots, and provide people with healthy and delicious food.
