Based on different concentrations of biological activity water,this article does research on the effect of corn seeds germination and seedling growth,it provides data support and theory basis to the promotion and application of biological activity water in planting industry.Corn seeds zheng dan 985 which is commonly planted in our country is choosed to be the experimental material.
Experimental analysis Experiment reagent and material Reagent of determination of the content of chlorophyll calcium carbonate,quartz sand,95% ethanol solution,biological activity water(the chemical characteristics of biological activity water is EC=0.2170ds/m ;pH=8.3).
After cleaning,drying and shearing leaves which have already germinated,we should weigh accuracy 50mg,then put them in research pot,add 3ml 95% ethanol,and grind till the material completely turn to be white,then add 7ml 95% ethanol,grinding,and filtrate,take supernate and measure optical density which wavelength is between 665nmand 650nm,calculate content of chlorophyll according to the following formula: Chlorophyll a(g/mg)=13.95×D665-6.88×D650；chlorophyll b(g/mg)=24.96×D650-7.32×D665; total chlorophyll(g/mg)=20.2×D650+8.02×D665;repeat the test 3 times,and conduct the date with statistical analysis.
