Abstract
The effect that five kinds of colloidal polymers did to seed germination and growth in sand was studied through orthogonal experiment in this paper. The water consumption, germination rate, growing and shoot length of five kinds of plants were investigated by changing the type and amount of natural colloidal polymers, soil and bio-fertilizer. Furthermore, the soil crust effect and the biomass of soil around sand seeds were analyzed in different conditions. It can be seen from the analysis of variance result that the types of colloidal polymer played a crucial role in water consumption of seed, and the water consumption was the smallest when Konjac Glucomannan was added with 911.14g/g. And the primary factor was plant species that effected germination rate of seeds, growing and plant height. Besides, the soil depth, plant species, polymer type and mass of polymer significantly influence the soil crust effect all. However, the amount of bio-fertilizer played an inhibiting part on biomass of soil.
