Energy-saving and temperature-increasing strawberry elevated medium cultivation device

Abstract

The invention discloses an energy-saving and temperature-increasing strawberry elevated medium cultivation device. The device comprises a groove seat, an inner cultivation groove formed in the grooveseat and a drainage channel located at the part between the groove seat and the inner cultivation groove; the inner cultivation groove comprises groove walls and a groove bottom, the groove walls arearranged on two sides of the groove bottom, and a space for accommodating cultivated mediums is formed in the part between the groove walls and the groove bottom; a plurality of first drainage holes for draining are formed in the groove bottom; a plurality of second drainage holes for draining are formed in the groove seat. According to the device, the drainage channel is formed in the part between the inner cultivation groove and the groove seat, water-gas contradiction of the cultivated mediums is better solved to improve the heat-preserving performance of the cultivation groove, and the difficulty of heat-preserving covering of large greenhouses and the problem of higher cost of heating energy consumption are relieved.

Description

technical field [0001] The invention relates to a strawberry cultivation device, in particular to a strawberry elevated substrate cultivation device. Background technique [0002] Strawberry (Fragaria ananassa.Duch) is a perennial evergreen herb of the Rosaceae genus Fragaria. Strawberry berries are fragrant, juicy and nutritious. With the improvement of people's living standards in our country and the rapid development of leisure and sightseeing agriculture, strawberry has become a major fruit for facility cultivation. In particular, it can be listed on the Spring Festival and New Year's Day by promoting cultivation. As a fresh fruit, it has strong market competitiveness and is economical. Benefits and social benefits are higher. [0003] The traditional strawberry planting method is mainly soil ridge cultivation. Strawberry soil cultivation is susceptible to facility soil salinization, continuous cropping obstacles, and soil-borne diseases, resulting in reduced strawberr...

Problems solved by technology

And do not play the effect of insulation tank like this technology, also do not increase drainage equipment

At the same time, the above two patents do not fundamentally solve the problems of the difficulty of covering and heat preservation of large-scale greenhouses during the low temperature period in winter and the high energy consumption of heating equipment.

[0007] The applicant has solved the problem of water-air contradiction in strawberry cultivation tanks (see Chinese patents 2014104756361 and 2015207143523 for details), but neither has fundamentally solved the problem of low temperature of low-temperature substrate in winter, nor solved the difficulty of large-scale greenhouse insulation coverage, The problem of high energy consumption of heating equipment
