A kind of trough planting method of nano-selenium yam

Abstract

The invention discloses a groove-type planting method of nano-selenium Chinese yam. Deep soil is crushed and made to float to be mixed with cultivated soil through a deep plowing technology, by adding a certain amount of biological-organic fertilizer containing nano-selenium, the soil is fertile, loose, rich in organics, and is more suitable for growth of the Chinese yam, the selenium content of the Chinese yam is increased, and the nutrition and medicinal value of the Chinese yam are increased. A plurality of U-shaped planting grooves are arranged for planting the Chinese yam, the Chinese yam can transversely grow along the U-shaped planting grooves and is easy to plant and harvest, labor intensity is relieved, and production cost is reduced. Meanwhile, the planting grooves are made of materials with mesh holes, palm bark is laid inside the planting grooves, the breathability and water permeability of the planting grooves can be effectively improved, and waterlogging and droughts are both effectively prevented. A double-layer planting method is adopted, the utilization area of land is effectively increased, and production and income are both increased largely.

Description

Technical field [0001] The invention relates to the field of planting, in particular to a groove planting method of nano-selenium yam. Background technique [0002] Yam, also known as Huai Yam and Guang Yam, belongs to the Dioscoreaceae family. It is a perennial entwining herbaceous plant. Yam is used as medicine with tuberous roots. It has a sweet, flat taste and has the effects of invigorating the spleen and lungs and strengthening vital energy. It is a kind of medicine and food. Vegetable varieties have high nutritional and health value and have always been welcomed by the people. [0003] The tuber of yam grows deeply, and it is time-consuming and laborious to collect the whole ridge, and it is easy to damage the tuber. Huaishan requires warm, humid, and sunny environmental conditions. It grows well in a deep, fertile, relaxed, and well-drained sandy soil. It is afraid of drought and waterlogging. It generally requires deep soil, good air permeability, and richness. Organic m...

Problems solved by technology

[0004] 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 at present: First, the labor load is large and the cost is high. The traditional yam production method is To make yam fleshy taproots grow vertically deep into the soil, it takes a lot of labor to dig planting ditch and excavate and harvest, 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 output; in view of this problem, Those skilled in the art are also constantly trying new methods, such as the yam planting method of mechanized ditching. Although the labor intensity of yam planting has been solved to a certain extent, yam harvesting is still manual excavation, and the workload is still relatively large. the second, the continuous cropping obstacle is serious, and the yam production process consumes a lot of soil fertility, so it is difficult to form an ideal output by continuing to plant yam on the field of planting yam for two consecutive years. Therefore, there is an urgent need for a new method to solve the above technical problems
