Extra sweet potato root dressing technology
In the middle and late growth stages of sweet potato, the growth of stems and leaves slowed from the peak, and the tubers entered a rapid expansion period, generally in early September. At this time, the temperature difference between day and night gradually increased, the lighting conditions became better, and the stem and leaf skeletons also formed. However, due to the rapid growth of stems and leaves in the early stage, a lot of nutrients were consumed, and sweet potato stalks are in a period of enlargement, which is also a critical period for the formation of yield, and requires a large amount of phosphorus and potassium fertilizers. In this case, insufficient supply of nutrients in the soil will reduce production. Therefore, it is necessary to apply extra-root fertilizer. The specific method is: spraying with 1% potassium phosphate solution or 0.3% potassium dihydrogen phosphate solution, with 150 kg of fertilizer solution per acre of sweet potato fields, sprayed once every other month, can effectively improve the function of the foliage, prevent premature aging, In order to enhance photosynthesis, it is beneficial to the transport of nutrients in the plant body and the accumulation in the tuber, and to increase the yield of sweet potato.
