Sweet potato, as one of the important food crops, is rich in nutrition and delicate in taste, and is deeply loved by the general public. So how to grow sweet potatoes scientifically and effectively?This article will provide you with a detailed and practical guide.
The first step is to select a high-quality sweet potato variety or breed it for detoxification. This is crucial because high-quality varieties have good resistance to drought, adversity and disease, which greatly prevents common problems such as black spot and mole, allowing yields to increase by more than 30%. After virus-free propagation, the seedlings can be inoculated directly without the need to refine the seedlings again. If conditions permit, self-cultivation is a better choice, which can reduce costs and ensure planting results.
In terms of planting methods, we advocate the promotion of the "lying seed" method. This not only subverts the traditional vertical planting method, but also makes the sweet potatoes grow more neatly and full. For example, dig a long hole with a shovel about a depth of about 100 minutes, then put in a small amount of sweet potato seeds, lay the bottom two-thirds flat at the bottom of the pit, and tilt the head upwards at the mouth of the pit, and then water the soil to cover it with appropriate amount of water. This planting method can avoid mutual interference between seeds, so that all sweet potatoes are evenly distributed and the yield is more stable.
In addition to this, mulching is also a recommended technology. It can increase the soil temperature in winter and spring, enhance the vitality of potato vines, and further help them to tiller early. At the same time, the plastic film has high permeability and waterproof performance, which can effectively prevent the evaporation of water in the soil, so as to play the role of water retention and heat preservation.
Proper fertilization is also a critical step. For example, during the vigorous growth period of sweet potatoes, potassium dihydrogen phosphate fertilizer is sprayed once a week. If there is too much common nitrogen, it will promote the excessive growth of stems and leaves, resulting in the inability of sweet potatoes to grow sufficientlySpraying potassium dihydrogen phosphate can not only adjust the quality of the tubers, but also achieve the purpose of increasing the yield.
Finally, it should be noted that timely adjustment of potato vines is also an important means to improve yield. Lifting the stems and vines can effectively prevent the spread of fibrous roots and prevent excessive nutrient loss, which in turn adversely affects the accumulation of nutrients in sweet potatoes. When the planting scale is large, paclobutrazol spraying can also be considered to control the shoots and keep the green, so as to achieve the purpose of saving fertilizer.
