Chinese yam matrix transverse cultivation method

Abstract

The invention relates to a Chinese yam matrix transverse cultivation method. The Chinese yam matrix transverse cultivation method is characterized by comprising the following steps of (1) preparing cultivation matrix for Chinese yams, (2) preparing Chinese yam seeds and accelerating germination, (3) preparing a matrix cultivation trough and a field facility layout, (4) filling matrixes, (5) sowing and planting seedlings, (6) tending a field and (7) harvesting. The Chinese yam matrix transverse cultivation method remarkably lowers labor intensity when the Chinese yams are cultivated and harvested, saves producing cost, and is convenient to popularize in a large scale. Furthermore, the Chinese yam matrix transverse cultivation method overcomes successive cropping obstacles to a large extent, and largely improves the yield and the quality of the Chinese yams.

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 taproot of yam grows 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 about 1.2-1.5 meters, and the width is 0.30-0.40 meters. The amount of earthwork per plant is 0.18 ~ 0.3 cubic meters, the workload is quite huge, and the labor cost is as high as more than 3000 yuan / mu, which limits the large-scale production of yam and the improvement of yield; for this problem, those skilled in the art are also constantly trying new methods. For example, the yam planting method of mechanized ditching solves the labor intensity of yam planting to a certain extent, but the harvesting of yam is still manual excavation, and the workload is still relatively large; the casing cultivation technology of yam, although this technology Appropriately reduces the amount of labor in 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
