Example Embodiment

[0027] The present invention will be further described in detail below in conjunction with the drawings.

[0028] As shown in the figure, the soilless culture system includes a foam plastic tank 3, a vent pipe 7, a liquid collection tank or a liquid supply tank 12, a hot blast stove 15, an axial fan 14 and an ozone generator 13 and so on. The upper inner diameter of the foamed plastic tank 3 is 30cm wide, the lower inner diameter is 25cm wide, the inner diameter is 25cm high, the foam tank is 3cm thick, and the single length is 1m. It can be extended according to the greenhouse structure. After the length of the cultivation tank is determined, use a 0.1mm thick plastic film 2 Lining the periphery of the foam plastic tank 3, the spacing between each cultivation tank is 40-80cm. The 0.1mm thick plastic film 2 lining the periphery of the foam tank can play a role in retaining fertilizer and water, preventing the water and fertilizer sprayed from the drip irrigation belt 1 from losin...

Abstract

The invention relates to a soilless culture trough and an application thereof, and belongs to soilless culture equipment. The soilless culture trough comprises a foamed plastic trough body and is characterized in that a plastic film is lined on the inner wall of the trough body, river sand is filled at the lower part of the trough body, a culture medium is arranged at the upper part of the trough body, a piece of braid shield fabric is arranged between the river sand and the culture medium, a vent pipe is buried at the bottom of the river sand, a piece of non-woven fabric wraps the outer wall of the vent pipe, one end of the vent pipe extends out of the trough body, the other end of the vent pipe is closed, and air vents are formed in the wall of the vent pipe. The purpose of uniform air outgoing of the vent pipe is realized by using a simple method in which the non-woven fabric and the sand are adopted, and the cost is low. Problems in four major medium soilless culture planting processes, including medium warming, medium ventilation, medium drainage and medium sterilization, are solved by one set of vent pipe, and one pipe can be used for multiple purposes.

Description

Technical field [0001] The invention relates to the field of plant cultivation, in particular to a soilless cultivation tank and its application, and is an integrated technique of substrate heating, ventilation, drainage and disinfection in ecological substrate soilless cultivation. Background technique [0002] In the past 20 years, my country's facility horticulture industry has developed rapidly, but the continuous cropping obstacles of facility soil have become increasingly serious, which has become a bottleneck for the sustainable development of facility industry. The ecological substrate soilless cultivation technology has solved the serious shortage of arable land resources and water resources in our country, the low efficiency of facility vegetable production, and the increasingly serious obstacles of facility soil continuous cropping. At present, the ecological substrate soilless cultivation has been used in 31 provinces (regions) across the country. , City) promotion, a...
