Planting techniques of wild sweet potato

Wild sweet potato, also known as sweet potato bubble, sweet potato and so on, is a kind of deciduous creeping woody vine of Moraceae. Wild sweet potato is originally a kind of wild fruit, but the whole plant of wild sweet potato can be used as medicine, which has the effect of dispelling wind and relieving menstruation. And it also has various uses such as edible, greening and ornamental, and its economic value is very high. So how to grow wild sweet potato? The following editor brings you the planting technology of wild sweet potato, let's have a look!

1. Land preparation and seed selection

First of all, we should choose a good planting soil, wild sweet potato is suitable to grow in the soil with deep soft soil, high fertility and good drainage and irrigation. And although the wild sweet potato is a kind of wild fruit with strong growth ability, it can not be continuous cropping, and it must be rotated for at least three years. After selecting the land, the soil will be ploughed deeply, combined with base fertilizer, fully watered, and then the varieties with excellent high yield and strong disease resistance will be selected. Seed dressing with new high fat membrane can improve the insect resistance of seeds, reduce bacterial infection, strengthen seed respiration and improve germination rate.

2. Sowing seeds at the right time

The growth period of wild sweet potato is very short, if planted in May, it will probably mature in June, and if it is not harvested in time, the wild sweet potato will gradually rot. And wild sweet potato plants only bear fruit once a year, so when sowing, we should take into account the market demand, weather and other factors to control the sowing time. If the market is not good, the planting efficiency will plummet. After selecting the sowing time, we should control the sowing density and sow. After sowing, we can spray appropriate amount of new high-fat film, disinfect the soil, improve the soil moisture and fertilizer conservation capacity, prevent soil consolidation, and promote the emergence of seedlings and soil breaking.

3. Water and fertilizer management

The growth of wild sweet potato needs a certain amount of water, so we should water it properly in the process of planting. Especially after the closure, about 7 days need to be watered to ensure that the soil is moist and promote the wild sweet potato to blossom and bear fruit. Wild sweet potato has strong growth ability and great demand for nutrition, so it is necessary to do a good job of topdressing while watering. Especially in the peak growth period, the ratio of nitrogen, phosphorus and potassium should be increased, and urea and compound fertilizer should be applied properly according to the growth and soil fertility of wild sweet potato to promote plant growth.

4. Field management

The plants of wild sweet potato are almost all creeping on the ground, especially in the later stage of growth, it will be all over the garden. Therefore, in the early stage of growth, we should do a good job of weeding to prevent weeds from grabbing the growth and nutrition of wild sweet potato, and in the later stage, weeding will become very difficult. Only weeding in the early stage can ensure the growth of plants in the later stage. The incidence of diseases and insect pests in wild sweet potato is low, but there are occasionally diseases and insect pests such as leaf-eating pests and root rot. We should often observe the orchard, do a good job of prevention, disinfect regularly, and remove the diseased plants together with the soil after the disease.

The above is a brief introduction to the planting technology of wild sweet potato. It should be noted that although the market price of wild sweet potato is relatively high, the current planting benefit is not very good. Because the wild sweet potato growth environment and planting technology and other factors lead to the yield of wild sweet potato is not high. Now if we want to grow on a large scale, we should carry out comprehensive development, and if we sell fruit alone, the planting efficiency is low.
