Soilless seedling-cultivation device and method for vegetables in gardens of high-altitude agricultural and pastoral areas

Abstract

Provided is a soilless seedling-cultivation device and method for vegetables in gardens of high-altitude agricultural and pastoral areas. The soilless seedling-cultivation device and method are characterized in that the device is of an n-shaped structure and has three layers of cultivation racks and is integrated designed and composed of a steel structure, lighting, heat-preserving, ventilating, irrigating, cultivation bed and power systems; the device uses a seedling-cultivation management method for vegetables in all kinds; the steel structure is composed of a framework, cross beams and the like outside the device; a lighting system is a polyvinyl chloride plastic film lighting surface adopting sunlight as a light source; a heat-preserving system is composed of a double-layer plastic film, an outer-hanging heat-preserving quilt and a heat-preserving pad at the indoor bottom; a ventilating system is composed of mobile ventilating windows and doors on two sides; a cultivation bed system is composed of a polyvinyl chloride plastic film and a cultivation medium; the seedling-cultivation management method for vegetables in all kinds uses an organic medium as the medium for breeding and cultivation of vegetable seedlings so that functions of ventilating, decreasing temperature and eliminating humidity are fulfilled; and lighting daytime is prolonged by means of a movable device. The soilless seedling-cultivation device and method for vegetables in gardens of high-altitude agricultural and pastoral areas have following beneficial effects: the device can be utilizes as effective equipment for production or scientific researches and has a great business prospect.

Description

technical field [0001] The invention relates to the field of vegetable crop cultivation, in particular to a soilless garden vegetable seedling cultivation-cultivation device in a high-altitude low-temperature area and a matching method thereof, belonging to the category of facility agriculture. Background technique [0002] Vegetable crops are rich in variety, providing nutrients that meat and grains cannot provide for human health, and balancing the acid-base environment in the body, which is an irreplaceable food to ensure human health. Nutritionists propose that a healthy diet structure is "taking vegetables and fruits as 'staple food', grain and meat as 'non-staple food', annual per capita vegetable consumption 120kg-180kg, fruit 75kg-80kg, grain 60kg, meat 45kg-60kg ". Compared with grain, meat and fruit, most vegetable products are not resistant to storage, and eating fresh vegetables is the premise to ensure human health. In order to effectively meet the needs of Ch...

Problems solved by technology

However, so far, for farmers and herdsmen in high-altitude areas of Tibet, the amount of vegetable consumption has not been basically met, let alone the demand for vegetable quality

In 2014, with the help of the Tibet Science and Technology Coordination Research Project, we conducted a survey on the current situation and trend of vegetable consumption by farmers and herdsmen in 100 villages in 36 counties of Tibet. County towns and agricultural and pastoral areas above 4,000 meters above sea level have a very urgent demand for vegetables, and I hope the government can effectively solve them; (2) The government spends a lot of money to build greenhouses in various places, but the greenhouse film is easily damaged due to strong winds, and the supporting irrigation measures cannot solve the problem. In place, poor production technology of farmers and herdsmen, etc., the utilization rate of greenhouses in many places is low. Even after one season of planting in the year of construction, the greenhouse film was damaged by strong winds in winter and was no longer used and abandoned. Most areas have been abandoned due to high costs and other reasons. There is no greenhouse; (3) Some vendors transport long distances and sell at high prices. Although it brings hope to farmers and herdsmen to eat vegetables, the high price makes most farmers and herdsmen only buy low-priced vegetables, and it is difficult to deliver vegetables due to heavy snow in winter. home-cooked

[0003] At present, although there are several types of small greenhouses suitable for the cultivation of courtyard gardening plants on the market, these types of facilities have the following problems: first, the cultivation area is limited, second, the cost is high, third, it is difficult to effectively keep warm, and fourth, they cannot be moved
