Glass-stem thermometer: 0～100 ℃
The cryogenic thermostat water-bath
Punch tool
Timing register
Cotton duck garden sheet: 21 3 strands * 21 4 strands of fine canvases, make that the garden sheet of diameter 30mm is standby (should wear gloves when producing the garden sheet with punch tool.Operation keeps away manual-free and directly contacts canvas)
(2) determination step
Slowly splash in the beaker that fills 200ml distilled water with pipette, extract 0.4ml sample (if too thick sample 0.4 gram that weighs in the balance of sample), sample adds with glass stick and slowly stirs evenly, place 25 ± 1 ℃ of waters bath with thermostatic control, keep 25 ± 1 ℃ of the interior solution of beaker, treat beaker liquid level lather collapse, after canvas garden sheet kept flat solution surface, timing.When the canvas disk was settled down to beaker bottom, record was put cloth to sedimentation required time (in Sec) parallel testing 10 times, gets its mean value, and will reject at a distance of the above data of ± 20Sec with mean value, and then ask its mean value, then be penetration time.
Two, formulation selection
For the fertilizer efficiency of clear and definite calcium lignosulfonate with select prescription preferably, in plastic tent cucumber, under the condition of general planting fertilising, spend preceding, spend back, each spray of fruiting period once, carried out following test.
(1) different PH are to the influence (table 1) of calcium lignosulfonate fertilizer efficiency
If: handle 1 (contrast)-general planting fertilising spray clear water
Handle 2-calcium lignosulfonate 30% and be diluted with water to 100%
Handle 3-calcium lignosulfonate 30%, with adding water to 100% with PH6 among the KOH
Handle 4-calcium lignosulfonate 30%, with adding water to 100% with PH7 among the KOH
Handle 5-calcium lignosulfonate 30%, with adding water to 100% with PH8 among the KOH
Handle 6-calcium lignosulfonate 30%, with adding water to 100% with PH9 among the KOH
Handle 7-calcium lignosulfonate 30%, with adding water to 100% with PH10 among the KOH
If the too high aqueous solution of lignosulfonic acid calcium contents is too thick, it is not easy to operate to add other materials, therefore only adds 30%.
Table 1 different PH is to the influence of fertilizer efficiency
Last table explanation: calcium lignosulfonate has the fertilizer efficiency effect, but the following underproduction of relevant PH6 with the size of pH value has production-increasing function more than the PH7, and the volume increase of PH8 is more obvious little with PH9-PH10 difference.Therefore selecting calcium lignosulfonate for use is raw material, and control PH8 is for suitable during production.
(2) Different Alkali is to the influence (table 2) of calcium lignosulfonate fertilizer efficiency
