What method can make sweet potatoes do not need turning vines? Sweet potato cultivation is very common in our rural areas, and the vitality of this crop is relatively tenacious, it is not strict with the soil requirements, but in loose fertile, good drainage, good permeability of soil growth more vigorous.Sweet potato is a delicious and nutritious crop, which has been widely welcomed by the market.So when we grow sweet potatoes, if the leaves of sweet potatoes grow vigorously, but without turning the rattan, will the yield of sweet potatoes be reduced? Before the transplantation of sweet potato seedlings, we applied basic fertilizer to the soil.General conditions permit the use of some decomposed farm manure, such as chicken manure, duck manure, cow manure and other high-quality farm manure to spread on the soil, and then fully make the farm manure and soil fully and evenly mixed.In this way, the requirement of nutrients for sweet potato plants in the process of growth can be ensured.For general soils, we can apply about 3000 kilograms of farm manure per mu, and add about 10 kilograms of superphosphate fertilizer plus 8 kilograms of ammonium bicarbonate fertilizer. Secondly, after the sweet potato vine grows to a certain stage, its sweet potato vine will grow aerial rooting, which directly roots in the soil, in this way to meet the needs of sweet potato vine leaves for nutrients.Therefore, if some sweet potato plots with sufficient basic fertilizer were not converted into vines, the longer and more vigorous the sweet potato vines would be, the longer and longer the vines would be.However, this will lead to the loss of nutrients and adequate nutrients in sweet potato root tubers, and eventually lead to small size and low yield of sweet potatoes.For many farmers, if they grow a lot of sweet potatoes, then turning vines is indeed a relatively laborious and labor-cost thing. So whenever we plant sweet potato vine leaves grow vigorously, we have to turn it over, so that by reducing the number of sweet potato vines through aerial rooting to absorb nutrients.Thus, the sweet potato tubers increased the absorption of nutrients, and eventually promoted the expansion of sweet potatoes.But the method of not turning the vine can also ensure high yield of sweet potato. We can isolate the contact between sweet potato vine and soil by covering the soil surface with plastic film. It can also inhibit the growth of sweet potato vine leaves and promote the expansion and high yield of potato pieces.On the one hand, some short-rattan sweet potato varieties can also be purchased for planting, in order to achieve the goal.
