Filter apparatus and count method for counting porphyra spores

Abstract

The invention relates to a filter apparatus and a count method for counting porphyra spores. The apparatus comprises a piston rod and a piston cylinder, wherein the piston rod enters the piston cylinder from one end of the piston cylinder and is arranged in the piston cylinder in a reciprocating manner, a water inlet hole is formed in the upper side wall of the piston cylinder, the water inlet hole is communicated with a sampling tube by virtue of an electromagnetic valve, and the sampling tube is internally and serially connected with a water pump; the middle portion of the piston cylinder is converged, a manual valve is arranged at a converged position, the piston cylinder forms a water storage cavity at the upper portion of the manual valve and forms a paper filter cavity at the lower portion of the manual valve; and a lower opening of the paper filter cavity, i.e. an opening of the piston cylinder is connected with a pressure block with a filter water outlet in the middle portion, the pressure block presses a piece of filter paper at the opening of the paper filter cavity, the filter paper is white, and pores of the filter paper are smaller than porphyra spores. Sample spore fluid with sufficient water is filtered by the filter paper, so that the spores are intercepted on the filter paper, the number of the spores on the filter paper is observed by a microscope, and then the spore concentration in an entire culture pond is then calculated.

Description

technical field [0001] The invention relates to the field of laver spore counting equipment, in particular to a filter device and a counting method for laver spore counting. Background technique [0002] In the process of laver planting, the number of spores in the spore water needs to be monitored. The existing laver spore counting method is to take the spore water through a counting frame with glass slides and place it under a microscope for direct observation and counting. For the cultivation tank of laver spores As far as the water volume is concerned, it is difficult to obtain a representative and sufficient sample water volume with the existing technology and sampling methods, which often leads to a large deviation between the counting result and the actual spore concentration. Contents of the invention [0003] The purpose of the present invention is to solve the problems of the technologies described above, and a filter device and counting method for counting laver...
