Criticize and apply, apply 60 kilograms altogether, be first dissolved in water before applying every time, be then uniformly spread to again in pond.
The collection of test water sample：Gathered 1 qualitative sample and 1 in October 30 in each sampled point laid respectively fixed
Amount sample.The collection of qualitative sample：With No. 25 plankton nets, on water body top layer to 0.5m depths, slowly drag around " ∞ " shape
1-3min, the sample of collection is fixed with 1.5% Lugol's；The collection of quantitative sample：After the sampling of 5L lucite hydrophore,
With No. 25 plankton net filtrations, the water sample of filtration residue is filled in 50ML plastic bottle, is fixed with 1.5% Lugol's.
（1）Qualitative survey result
Pond 3# identifies 3 14 kinds of phytoplankton, wherein 7 kinds of diatom altogether, and cyanophyceae is 2 kinds, and chlorella is 3 kinds and dinoflagellate 2
Kind；Pond 4# identifies 5 39 kinds of phytoplankton altogether, has 30 kinds based on diatom, 4 kinds of cyanophyceae, 3 kinds of chlorella, dinoflagellate and Euglena
Each a kind；At off-lying sea, the multiformity of phytoplankton is relatively low, identifies 3 12 kinds of phytoplankton, wherein 6 kinds of diatom, cyanophyceae altogether
4 kinds, 2 kinds of chlorella.Each sampled point phytoplankton register is specifically shown in Table 1.
Table 1 phytoplankton register
In terms of survey result, the sociales of pond 3# are inconspicuous, and the phytoplankton species of pond 4# are many, and sociales are mainly
The Nitzschia of Bacillariophyta, Navicula and bar algae U.S. wall algae, off-lying sea phytoplankton species are few, but sociales to be evident as Denmark thin
Post algae.
（2）Quantitative interview result
Quantitative analyses are carried out to each sampled point plankton, calculate each sample point phytoplankton density and Biomass,
Result is as shown in table 2.
The each sampled point phytoplankton density of table 2 and Biomass
As can be seen from Table 2, the phytoplankton density of pond 3# and off-lying sea and Biomass are relatively low, are substantially at lean battalion
Foster state, pond 4# phytoplankton density and Biomass are higher, have the trend to middle Nutrition Development from lean nutrition.Can also simultaneously
Find out, the phytoplankton structure of pond 3# is diatom-chlorella-cyanophyceae and deposits, and the diatom content of pond 4# and off-lying sea is equal
More than 50%, its architectural feature is based on diatom, and other class phytoplanktons are simultaneously deposited, and mariculture special fertilizer of the present invention is described
The amount reproduction of the beneficial algae such as diatom in water body, chlorella can be promoted, quickly realize seawater quality and foster and apply fertilizer.
The foregoing is only presently preferred embodiments of the present invention, all impartial changes done according to scope of the present invention patent with
Modify, all should belong to the covering scope of the present invention.
