Chinese yam matrix transverse cultivation method

Abstract

The invention relates to a method for horizontal cultivation of yam substrate, which is characterized in that the method comprises the following steps: 1) special cultivation substrate for yam, 2) preparation and germination of seed potato, 3) preparation of substrate cultivation tank and layout of field facilities, 4) Substrate filling, 5) Sowing and planting seedlings, 6) Field management, 7) Harvesting. The method significantly reduces the labor intensity of yam planting and harvesting, saves production costs, and is convenient for large-scale promotion; secondly, the method largely overcomes continuous cropping obstacles and greatly improves the yield and quality of yam.

Description

technical field [0001] The invention belongs to the soilless cultivation technology of vegetables, and specifically relates to a light-type, high-yield and high-efficiency cultivation technology of yam, and is a method for horizontal cultivation of yam substrate. Background technique [0002] Chinese yam, also known as Huai yam and Guang yam, is a herbaceous plant of Dioscoreaceae, a perennial herb with winding perennial roots. The common effects of yam are as follows, 1) invigorate the spleen and stomach, and help digestion. Yam contains amylase, polyphenol oxidase and other substances, which are beneficial to the digestion and absorption of the spleen and stomach. Nourishes the kidney and nourishes the essence, yam contains a variety of nutrients, has the effect of strengthening the body, nourishing the kidney and nourishing the essence, 3) nourishing the lung and relieving cough, yam contains saponin, mucus, has the effect of lubricating and moisturizing, so it can benefi...

Problems solved by technology

[0003] Chinese yam is becoming more and more popular not only at home, but also abroad, and the market demand is increasing. However, the following problems exist in the cultivation and production of yam: 1) The labor is heavy and the cost is high. The traditional production method of yam is to use The fleshy taproots of yam grow vertically deep into the soil, and it takes a lot of labor to dig the planting ditch and harvest. Generally, the depth of the ditch for planting and harvesting is 1.2 to 1.5 meters, and the width is 0.30 to 0.40 meters. The soil volume of yam is 0.18~0.3 cubic meters, the workload is quite huge, and the labor cost is up to more than 3000 yuan / mu, which limits the large-scale production and yield improvement of Chinese yam; for this problem, those skilled in the art are also constantly trying new methods. Methods, such as the yam planting method of mechanized ditching, have solved the labor intensity of yam planting to a certain extent, but the yam harvesting is still manual excavation, and the workload is still relatively large; the casing cultivation technology of yam, although this technology is appropriate It reduces the labor of yam planting and harvesting, but the cost of casing is much higher than the cost of labor, so it is difficult to promote

2) Continuous cropping obstacles are serious, and the yam production process consumes a lot of soil fertility. Therefore, it is difficult to grow yam on the field where yam has been planted for two consecutive years to form an ideal yield. Not only does it need to invest a lot of fertilizer, but also the disease of yam Severe, poor growth, greatly reduced yield
