Problems solved by technology

Purple yam contains a large amount of purple anthocyanins, which is beneficial to the treatment of cardiovascular diseases, and has the effect of anti-oxidation, beauty and beauty. The growth environment of purple yam is relatively harsh, and improper planting methods will also seriously affect the output and quality of purple yam. The purple yam planting is based on the vertical growth of the roots, which not only leads to the uneven development of the yam, the appearance is not beautiful, the fertilizer utilization rate is low, and it is easy to breed bacteria, and it is difficult to harvest, which increases the cost of planting and a large number of yams. manpower

Abstract

The invention relates to the field of Chinese yam planting and provides a method for increasing the yield of purple yams. The method comprises the steps of: (1) soil preparation: applying sufficient base fertilizer and adding river sand, gravels, pine needle leaves, fig leaves and saw dust into planting soil, so that purple yams are prevented from being infected with germs and being caught in waterlogging, nutrient ingredients in the soil can be absorbed by yam roots, and thus the nutrient value of yams is increased; (2) planting ridge arrangement: adopting a method of arranging planting grooves in planting furrows for arranging of planting ridges, so that yam rots grow transversely, the sun light, water and fertilizer absorption and utilization rates are higher, and yams are uniform in thickness and convenient to dig; (3) planting: giving full consideration to physiological features of yam seedlings in a planting process, wherein seedlings exposed to the sun can provide sufficient nutrients to large roots. The planting method can increase the yield of purple yams by 30-35% and reduce costs by 15-20%; the content of nutrients of purple yams exceeds a normal level.

Description

technical field [0001] The invention relates to the field of yam planting, in particular to a method for increasing the yield of purple yam. Background technique [0002] Purple yam is also known as "purple ginseng", also known as yam and long taro. The root tuber contains 1.5% protein, 14.4% carbohydrate, and contains a variety of vitamins and choline, etc., with extremely high nutritional value. It is rich in yam soap (natural DHEA), which contains various basic hormone substances. Often eating purple yam can promote the synthesis of endocrine hormones. The protein content and starch content of purple yam are very high, so regular consumption of purple yam is suitable for moisturizing the skin and promoting cell metabolism. It is a table dish. The main production areas are Jiangxi, Gannan, Guangdong, Taiwan, and Fujian. The Hakka people regard it as a health treasure, and it is also a frequent ingredient in Hakka snacks. Purple yam is also called "Purple Huaishan". Ac...
