According to research, potassium has the greatest impact on sweet potato yield. The purpose of sweet potato stems and leaves growth, the late expansion of potato block for the application of potassium, supplemented with green pollution-free microbial fertilizer Jinbao, can effectively achieve the purpose of high quality and high yield of sweet potato.
1, Shizujifei, organic fertilizer and Golden Baby microbial fertilizer combination. Although sweet potato has the characteristics of resistance to barrenness, it absorbs fertility during the growth period and consumes more nutrients in the soil. Therefore, base fertilizer must be applied in order to give full play to the high yield performance of sweet potato. For land with medium or above fertility, the average Mushi farmyard fertilizer 3000-4000 kg plus gold baby microbial fertilizer 1 to 2 kg. Because the sweet potato roots are mostly concentrated in 25-30 cm soil layers, the base fertilizer must be applied in a depth of 25-30 cm in order to facilitate root absorption.
2, skillfully applied top dressing, make up for nutrition, and promote healthy growth of plants. For underfertilized land, fertilizer is generally applied in the early stage of potato block expansion, and 7.5 to 10 kilograms of nitrogen, phosphorus and potassium ternary compound fertilizer may be topped off, and 1 to 2 kilograms of the microbial fertilizer may be added. The fertilization method is to apply a hole or water to dissolve the roots, each fertilizer 0.25 to 0.5 kg. Such as watering, goldfish microbial fertilizer should be 3 to 4 times the amount of dilution.
3. Scientifically use foliar fertilizer to balance nutrition and coordinate growth. Spraying foliar fertilizer can stimulate plant vigor, improve stress resistance, coordinate vegetative growth and reproductive growth, and greatly improve the magical effect of quality and yield.
During the whole growth period of sweet potato, the application of the microbial fertilizer can increase the resilience of sweet potato and increase the yield of sweet potato by more than 10% on the original basis. At the same time, the microbial fertilizer has the effect of fertilizing the soil and promoting the early ripeness of sweet potato, and plays an irreplaceable role in the cultivation of high-quality and high-yield sweet potato.
