Using method of the present utility model:
1) at least two this utility model product is used；
2) (this substrate passes through professional equipment the cup of one of them this utility model product to be filled a certain amount of standard substrates
Test)；
3) cup of other this utility model products is filled equivalent substrate to be measured or soil；
4) equivalent clear water is put into toward each cup；
5) with step 4) timing simultaneously；
6) after identical duration, cup is extracted；
7) water level in each this utility model product cup is judged；
8) retention ability judges: water level less than equal to standard substrates water level as reaching standard；
9) matrix porosity judges: water level less than equal to standard substrates water level as reaching standard.
The beneficial effects of the utility model are: this utility model simple in construction, can quickly be held by substrate portion and water storage part
Simply comparing of waterpower and porosity, little additionally, due to this utility model simple in construction volume, in that context it may be convenient to carry, it is simple to field
Between manage.
