| Abstract: | Using high-hydroscopicity resin seed-coating material to study its application effect on the plastic-plate dry-raised and scatteredtransplantation seedling.The result indicated that: High-hydroscopicity resin seed-coat was able to improve survival ratio of plastic-plate dry-raised seedling;abate the damage of bakanae disease,damping-off and thrips oryzae Williams;reduce cluster-root;increase the chlorophyll content of seedling,the plant relative moisture content,the plant soluble sugar and enhance nitrogen,SOD activeness of plant root and leaf;improve the photosynthesis speed and ratio of root-developing;accelerate seedlingstand;improve rate of tiller,leaf area index,the dry matter accumulates.Finally,effect of increase production of rice is abtained. |
