This experiment uses wheat straw and corn seeds as materials, laboratory preparation of different concentrations of wheat straw leachate treatment on maize seed and seedlings, the germination rates observed corn as well as physiological and biochemical parameters, recorded data analysis derived rule. First of Extracts on Seed Germination, and then study the leaching solution on the growth of maize seedlings: leaching solution with different concentrations of water treatment three leaves, the corn has been grown for some time to determine the physiological indicators of different groups (the same leaf chlorophyll content, root activity assay, MDA determination, POD activity, etc.). Finally, experimental data on the number of statistical analysis to draw appropriate concentration of leaching solution on wheat straw stimulated the growth of maize conclusions.
