Greenhouse for planting kalimeris

Abstract

The invention discloses a greenhouse for planting kalimeris, which comprises several greenhouse frameworks and a film covering at the outer parts of the greenhouse frameworks; the film and the greenhouse frameworks are commonly formed to be a planting space for planting the kalimeris; the front end of the planting zone is provided with a cooling zone, and water curtains are installed on the front and back end faces of the cooling zone; an impounding reservoir for providing circulating water for the water curtains is arranged in the cooling zone, and the back end on the greenhouse in the planting zone is equipped with a negative pressure blower controlled by a controller; the vertical outside of the film is covered with an external heat insulation material, the outer parts of the greenhouse frameworks are provided with external winding devices for winding the external heat insulation material; the back end of the planting zone is provided with a temperature sensor, and the temperature sensor is connected with the controller; the greenhouse can effectively reduce temperature, thus the greenhouse is under a constant temperature state and convenient to plant the kalimeris.

Description

Technical field [0001] The invention relates to a large shed, in particular to a large shed for planting Malan head. Background technique [0002] Malantou is a leafy vegetable with excellent medicinal and diet. It is a wild perennial plant originally from the perennial root. The market needs rapid growth in recent years. Malantou relies on its underground rhizomes to multiply and grow. When the temperature is suitable, the growth points of the underground stems will quickly arch out of the soil layer to produce tender branches for picking. Every time a twig is picked, side shoots will immediately grow in the leaf axils remaining on the above-ground stem below the shoot. After several pickings, more and more above-ground stems remain, and more and more side shoots grow in the leaf axils. It becomes extremely small and loses its commercial value. Vegetable farmers must dig it out and replant it. The current Malantou is generally wild in the open air. Malantou is planted in Octob...

AI Technical Summary

Problems solved by technology

At present, Malantou is generally wild in the open air. Malantou starts to be planted in October of the lunar calendar and grows until May of the next year. Between May and October, due to weather conditions and high temperatures, the stems and leaves of Malantou grow too fast. The taste is old, it cannot be eaten within a few months, and there is a blank in the market

The main function of the current greenhouse is to heat up the temperature in winter, therefore, it cannot be applied to the cultivation of Malantou
