A kind of method of soilless cultivation Chinese yam

Abstract

The invention discloses a soilless Chinese yam cultivation method. The method includes the steps of material preparation, preparation before planting, field planting of Chinese yam, frame setting-up, field management, pest control and harvesting. A customized sleeve and a matrix prepared by traditional Chinese medicine residue are adopted, careful management is performed after field planting, drip irrigation of water and fertilizer is performed regularly, pesticide is sprayed to prevent and control pest, and the Chinese yam can be harvested before beginning of winter. The Chinese yam planted by adopting the method is high in yield, uniform in length and thickness, rich in trace element and high in nutrient value, and yield of a single Chinese yam plant can reach 1.96kg. Dried Chinese yam is cylindrical, straight in strip, smooth, round, flush in two ends, white both inside and outside, firm in quality, high in mealiness, weak in taste, free of crack, hollowing and exploding head and high in medicinal value, moisture content is smaller than or equal to 12%, ash content is smaller than or equal to 2%, and extract is not smaller than 6.1%.

AI Technical Summary

Problems solved by technology

[0004] The traditional yam planting method has the following disadvantages: 1. It has high requirements on the soil, and the planting area is limited. It is only suitable for planting in areas with fertile soil, and it cannot grow in saline-alkali land, thus affecting the planting efficiency.

2. If the soil is not uniform in tightness and thickness, it will cause uneven thickness and uneven appearance of the tubers of yam, which will affect the yield of yam

4. Excessive use of pesticides and chemical fertilizers in the process of yam cultivation has affected food safety

5. The traditional planting of yam requires digging to a depth of more than 100cm when harvesting, and there is no machinery available, which is extremely labor-intensive
