Introduction to cultivation techniques and Management of Sweet Potato

Sweet potato, which is what we call sweet potato, sweet potato, etc., has been planted all over our country, which can not only be used as staple food, but also can be made into processed food, starch, alcohol and so on. Sweet potato has high nutritional value and tastes soft and glutinous, but don't eat too much at one time, which can easily cause flatulence. The roots, stems and leaves of sweet potatoes can be used as feed, and the requirements for planting links are not high. Let's take a look at the cultivation techniques and management points of sweet potato.

1. Seed selection and seedling raising

Seed selection is the key to the yield of sweet potatoes. Potato cubes should be planted with appropriate size, neatness, no invasion of diseases and insect pests, no wounds and other characteristics.

When the length of the potato cubes reaches about 30 centimeters, the seedlings can be planted and propagated.

2. Land selection and arrangement

When planting sweet potatoes, try to choose sandy loam or loam with good looseness, strong air permeability, moderate fertility and good drainage.

When planting, we should give foot base fertilizer, choose farm manure as the main fertilizer, and match it with chemical fertilizer.

3. Planting

If the top strong seedlings are planted, the growth is relatively robust, with top advantage, adequate nutrition in the later stage, good disease resistance, fast turning green, early rooting time and higher yield.

The common planting methods of sweet potato are direct insertion, oblique insertion, hook insertion, horizontal insertion and so on. the appropriate planting methods should be selected according to the local geographical environment and climatic conditions.

The selection of planting methods is directly related to the root of sweet potato seedlings, the formation and expansion of sweet potato lumps. In addition, the influence of planting depth is also great.

Reasonable close planting is beneficial to increase the yield of sweet potato, but it should be grasped according to different sweet potato varieties, soil fertility, season and so on.

4. Field management

The period from rooting to seedling returning to branching and tuber formation is an important stage of root rejuvenation of sweet potato, in which little water is needed and less nutrients are consumed. the main work is to check seedlings and fill gaps. The work should be done within five days after planting sweet potato seedlings to maintain the wettability of the soil and improve the survival rate of sweet potato seedlings.

The period from the luxuriant period of sweet potato stems and leaves to the expansion stage of sweet potato tuber is an important stage of nutrition accumulation, so we should pay attention to the work of water and fertilizer. When watering, we should master the method, not too much water, so as not to grow too much. Intertillage weeding is also very important, which can keep the soil loose, increase its air permeability, increase the soil temperature and reduce the phenomenon of weeds. Note that sweet potatoes are drought tolerant and do not need to be watered too much in the early stage, but they can be watered if the soil is too dry.

Sweet potato tuber expansion period to harvest is an important period of sweet potato root starch accumulation, this stage should be based on the actual situation of fertilizer.

Sweet potato is easy to be attacked by insect pests, so it must be prevented in advance and treated with medicine in time when diseases are found, so as not to affect the yield and quality.
