A kind of using method of the soilless cultivation tank of Chinese yam

Abstract

The invention relates to a use method for a soilless culture box tank for dioscorea opposita. The use method includes the following steps that a, a cultivation medium is prepared and disinfected; b, the box tank, a medium collecting position and a culture box are cleaned; c, the culture box is installed and filled with the medium; d, dioscorea opposita seedlings are transplanted; e, cultivation and management are conducted; f, the dioscorea opposita is harvested. The use method has the technical advantages that the action principle is clear and easy to understand, can be grasped by people of all ages and both sexes, and is not limited by the scientific and technological culture level; the specific soilless cultivation medium is adopted for cultivation of the dioscorea opposita, organic matter in the medium is high in content, nutrients are balanced, the purpose of the high yield of the cultivated dioscorea opposita is achieved, the average per unit yield is 4,162-5,766 kg / 667 m<2>, the adopted medium is disinfected with formalin or manually disinfected in a workshop or replaced in the workshop, and disease and pest damage caused by a cultivation medium for the dioscorea opposita and the negative effects caused by continuous cultivation are avoided.

Description

technical field [0001] The invention relates to a method for using a soilless cultivation tank of Chinese yam. Background technique [0002] Chinese yam (Dioseorea opposite Thunb) belongs to the family Stemonaceae, a plant of the genus Dioseorea. Yam is mainly used for medicine and then for food. It is also eaten mostly for medicinal purposes. When people eat yam, they think it can cure diseases, nourish, and of course satisfy hunger. Yam has developed to this day and has become an important international medicine and food crop. Yam mainly contains mucus juice, mannan, mannan polysaccharide, choline, glycoprotein, polyphenol oxidase, vitamin C, phytic acid, 16 kinds of amino acids, allantoin and 3,4-dihydroxyphenylethylamine , dopamine (domamine), etc., are important nourishing foods, which have pharmacological effects such as nourishing the spleen and stomach, promoting body fluid and benefiting the lungs, nourishing the kidney and astringent essence, etc. Treatment of...

Problems solved by technology

However, if these technologies are to be widely applied in the production practice of yam, there are still various restrictions. For example, the mechanical ditching harvester is suitable for large-scale planting bases with flat terrain, and ordinary growers cannot afford it. Uneven bases cannot be used; pipes, casings or semi-sleeves, and guide grooves control the growth direction of yam tubers by guiding them to allow yam tubers to grow in an approximately horizontal direction, which is convenient for harvesting and saves labor and effort, but ignores the geologic growth of yam tubers (vertical ground inclination ≥ 58.28°: the arc tangent function value of the reciprocal of the golden section value of the influence of gravity on crop growth), due to the pressure and gravity of the guide material wall during the tuber growth process (vertical ground inclination < 58.28° ) to produce a large number of yams, yams, and yams, which directly affect the commodity rate and quality of the tubers; the water-retaining and root-controlling bags have relatively high requirements, and are only suitable for family balconies and small farms for leisure agricultural development. Area planting cannot be promoted
