Soilless culture trough and application thereof

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...

AI Technical Summary

Problems solved by technology

[0003] At present, the heating of facilities in protected cultivation in my country basically adopts the method of air heating, and the heating of substrate mainly adopts the method of electric heating, which has high one-time investment and operation cost, and has a single effect.

The disinfection of the substrate is also to take the substrate out of the cultivation tank and then stack retting, perform solar disinfection in the cultivation tank or use medicament disinfection in the cultivation tank, which is laborious and laborious, and the disinfection effect is not thorough
