Sweet potatoes are a nutritious, delicious and delicious food, and they have great health benefits. With the emphasis on healthy eating, the demand for sweet potatoes is also increasing. Therefore, how to increase the yield of sweet potatoes has become a problem faced by many farmers. Here are some ways to get a high yield of sweet potatoes.
First of all, it is necessary to choose excellent sweet potato varieties. There are many varieties of sweet potatoes, and different varieties vary in terms of yield and quality. Therefore, when growing sweet potatoes, it is necessary to choose the right variety according to the local climate, soil and market demand. In general, it is easier to obtain high yields by choosing sweet potato varieties that are vigorous, disease-resistant, and adaptable.
Secondly, reasonable dense planting is one of the key measures to improve sweet potato yield. When planting sweet potatoes, it is necessary to determine the appropriate planting density according to factors such as variety characteristics and soil fertility. In general, in moderately fertile and well-drained soils, 3000-4000 sweet potatoes can be planted per mu. If the planting density is too high, it will lead to problems such as overcrowding, insufficient light, and increased pests and diseases, which in turn will reduce the yield.
Third, scientific fertilization is one of the important measures to improve sweet potato yield. When fertilizing, the type and amount of fertilizer should be determined according to factors such as soil fertility and sweet potato growth needs. Generally speaking, the growth of sweet potatoes requires nutrients such as nitrogen, phosphorus, and potassium, among which nitrogen fertilizer is an important fertilizer to promote the growth of sweet potato, and phosphate fertilizer and potassium fertilizer help to improve the disease resistance and yield of sweet potato. When fertilizing, it is necessary to pay attention to the appropriate amount of fertilization to avoid problems such as seedling burning and soil compaction caused by excessive fertilization.
Fourth, reasonable irrigation is one of the necessary measures to increase the yield of sweet potatoes. During the growth of sweet potatoes, the appropriate irrigation time and amount should be determined according to factors such as soil moisture and weather conditions. In general, it is necessary to irrigate in time during the dry season to keep the soil moist; In the rainy season, it is necessary to drain water in time to avoid problems such as root rot caused by soil waterlogging.
Fifth, strengthening pest control is one of the important measures to improve sweet potato yield. During the growth of sweet potatoes, they will be attacked by a variety of pests and diseases, such as sweet potato blast, black spot, aphids, etc. Therefore, it is necessary to strengthen the monitoring and control of pests and diseases, detect and control pests and diseases in a timely manner, and avoid yield loss.
Sixth, timely harvesting is the last step to increase sweet potato yield. At harvest time, the appropriate harvest time should be determined based on factors such as weather conditions and the ripeness of sweet potatoes. In general, harvesting sweet potatoes on a sunny day can reduce the effects of germs and moisture on sweet potatoes; Harvesting sweet potatoes at more than 80% maturity yields the best yield and quality.
In short, in order to improve the yield of sweet potato, it is necessary to select excellent varieties, reasonable dense planting, scientific fertilization, reasonable irrigation, strengthen pest control and timely harvesting. At the same time, it is also necessary to continuously explore and innovate planting technology and management mode to improve the efficiency and competitiveness of the sweet potato industry.
