Problems solved by technology

[0003] As one of the traditional Chinese crops, sweet potato is a food that people prefer. However, due to unreasonable planting methods, the yield of sweet potato is not high despite the wide planting area. The yield per mu of sweet potato can only reach 2800-3300 kg. Therefore, realizing the high yield of sweet potato is the main subject of research in recent years.

Embodiment 1

[0020] A high-yield planting method for sweet potatoes, which consists of several links: seedling raising, soil preparation, planting, topdressing water and fertilizer, and field management.

[0021] (1) Seedling cultivation: a, select the sweet potato with smooth skin, bright color, and no frostbite, cut the sweet potato in half, put the cut sweet potato into the nutrient solution, wherein, immerse one side of the cut in the nutrient solution, and the other One side is suspended in the air, and cultivated under constant temperature and humidity conditions; b. After the shoots grow to 8cm, pick them off and put them in the culture solution. Routine field management.

[0022] (2) Soil preparation: choose sunny and fertile soft soil, plow the soil deeply, spray 0.05% saline solution, and let it dry naturally. Before planting, lay plastic film on the soil surface, and cut the diameter on the plastic film at an interval of 10cm. A round hole of 5cm.

[0023] (3) Planting: On the...

Abstract

The invention belongs to the technical field of crop planting and specifically relates to a high-yield planting method of sweet potatoes. Through links including seedling culturing, land preparation, planting, topdressing of water and fertilizer and field management, root systems of the sweet potatoes are developed, the stress resistance is high, the environmental adaptability is high, and the emergence rate is 92% or above, the sweet potatoes sufficiently absorb the water and the fertilizer in later planting and grow rapidly, and besides, the demands of the sweet potatoes for macroelements and microelements during growth are met due to application of organic fertilizer; meanwhile, pesticides for treating diseases and pests are reasonably added, and diseases and pests are effectively reduced under the condition that the sweet potatoes are not damaged; the condition of soil damage due to excessive fertilization and pesticide application in order to obtain high yield of the sweet potatoes is also avoided. By means of the planting method, the yield of the sweet potatoes per mu can reach 5,100 kg or above, and the yield is substantially increased.

Description

technical field [0001] The invention belongs to the technical field of crop planting, and in particular relates to a high-yield planting method of sweet potatoes. Background technique [0002] Sweet potato, also known as sweet potato, sweet potato, sweet potato, etc., contains dietary fiber, carotene, vitamins and various trace elements. It is rich in nutrients and can be used not only as a staple food, but also processed into a variety of non-staple foods. Farmers love it. It has the effects of weight loss, bodybuilding, preventing sub-health, laxative and detoxification. It contains dietary fiber, which cannot be digested and absorbed in the intestinal tract. It can stimulate the intestinal tract and enhance peristalsis. Sweet potatoes have a special protective effect on the mucous membrane of human organs and can inhibit Cholesterol deposition, maintain blood vessel elasticity, prevent connective tissue atrophy in liver and kidney, and prevent collagen disease.
