A kind of soilless cultivation tank of Chinese yam

Abstract

The invention relates to a soilless culture box trough for dioscorea opposita. A culture box trough body (1) comprises unit culture troughs (2), medium collection boxes (3) and culture boxes (4). The soilless culture box trough for dioscorea opposita is characterized in that the culture box trough body (1) is formed by connecting the unit culture troughs (2) in parallel, the medium collection boxes (3) are connected to the lower portions of the two ends of the unit culture troughs (2), and the culture boxes (4) are connected in series and then arranged in the unit culture troughs (2). The soilless culture box trough for dioscorea opposita has the advantages that the equipment structure is simple, the box troughs are made of cement, the culture boxes and components thereof are made of hard plastic, manufacturing cost is low, the soilless culture box trough can be repeatedly used for 8-12 years at one-off input, and application and popularization are easy. According to the soilless culture box trough for dioscorea opposita, sliding wheels and sliding tracks are combined to bear the gravity of the culture boxes and soilless culture media, a lot of labor used for soil excavation in dioscorea opposita harvesting in a traditional culture method is omitted, labor is saved by 55-68%, and meanwhile damage caused to dioscorea opposita tubers in dioscorea opposita harvesting in the traditional culture method is reduced.

Description

Technical field [0001] The invention relates to a soilless cultivation tank for yam. Background technique [0002] Dioseorea opposite Thunb (Dioseorea opposite Thunb) belongs to the Stemonaceae (Stemonaceae), a plant of the genus Dioseorea. Yam is mainly used for medicinal purposes and then for consumption. The food is mostly for medicinal purposes. People eat yam because they think it can cure diseases, nourish, and of course can also satisfy hunger. Yam has developed to this day and has become an important international medicine and food. Yam mainly contains mucus juice, mannan, mannan, 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, with pharmacological effects such as tonifying the spleen and stomach, promoting fluids and lungs, nourishing the kidney and astringent essence. It is often used for spleen deficiency, less food, c...

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
