Method for cultivating dioscorea alata lirm.sp

Abstract

The invention discloses a method for cultivating dioscorea alata lirm.sp, and relates to the technical field of cultivation and plantation of purple sweet potatoes. The method comprises the followingsteps: after land preparation, carrying out fertilization by virtue of peanut cakes, processing potato seeds, carrying out seedling growing under proper conditions, and carrying out transplantation after buds with the lengths of 1.5cm-2.5cm grow from potato pieces; carrying out ridging before the transplantation: controlling the heights, widths and intervals of ridges, plant intervals and row intervals; carrying out double-row plantation, laying forage, and building a frame among the potato pieces, wherein the frame is used for being climbed by plants of the dioscorea alata lirm.sp; and afterthe dioscorea alata lirm.sp is mature, digging out the dioscorea alata lirm.sp. The method has the advantages that the peanut cakes obtained after oil squeezing of peanuts are taken as an organic fertilizer for replacing common nitrogen, phosphorus and potassium fertilizers, and a small amount of compound fertilizers are added during ridging, so that the production cost of a cultivation techniqueis low; by adding a proper amount of lime during the land preparation and the fertilization, diseases in soil can be prevented and treated, and the looseness of the soil is increased, so that root tubers of the dioscorea alata lirm.sp grow bigger, and the yield is high. Besides, by virtue of a built frame structure, the wind resistance of the plants of the dioscorea alata lirm.sp is enhanced.

Description

technical field [0001] The invention relates to the technical field of cultivation and planting of purple sweet potato, in particular to a cultivation method of purple sweet potato. Background technique [0002] Purple foot potato (Dioscorea alata Lirm.sp) is a kind of sweet potato. It looks irregular and flat, similar to a foot plate. It belongs to the genus Dioscorea (Dioscorea), also known as ginseng potato. Purple Foot Potatoes are rich in starch, a large amount of vitamins, proteins, and other active substances such as viscous polysaccharides, saponins, and trace elements that are very beneficial to the human body. The beneficial ingredients in it can assist in the treatment of cancer, lower blood lipids, and regulate blood pressure. It also has the effect of nourishing the lungs. , Physiological curative effect of strengthening the kidney and invigorating the spleen. Purple foot potato can be used as a conventional food to make a variety of dishes, which is deeply lov...

Problems solved by technology

[0003] At present, there are certain problems in the cultivation of purple-footed potato. For example, due to the excessive use of nitrogen, phosphorus and potassium fertilizers, in addition to the absorption of purple-footed potato, excess nitrogen, phosphorus and potassium fertilizers will remain in the soil, which will cause soil compaction. In the first year of planting purple-footed potato, the yield is high, but in the second or third year and later, due to soil compaction, the yield, meat quality and size of the purple-footed potato produced are not as good as in the first year

At the same time, due to soil compaction, it will also affect the water retention capacity, fertilizer retention capacity and permeability of the soil, making this piece of land not only unable to produce high yields of purple footed potato, but also unable to produce high yields of other crops

In addition, due to the excessive use of nitrogen, phosphorus and potassium fertilizers, the production cost of producers will also increase significantly.
