Abstract:

The Granular Flows effects of the wheat on yield and germinating was studied in order to better use the Granular Flows technology at farm. The two main cultivars for dry land, ‘Changhan 58’ and ‘Jinmai 47’, treated by different dosages of granular flows, had been experimented by indoor germinative test and plot tests in Changwu and Heyang. The results indicated that, the rate of the experimental germinability increased 1.0%-2.6% comparing the none-experimental samples, and the rate of germinating capacity increased 1.12%-4.82%. It also showed significant changes on its biological character at the seedling stage. There was significant difference of the root numbers between the experimental seeds and contrast seeds after 15 days of germinating. The experiments were 5.8%-7.1% decrease than the none-experiments for ‘Changhan 58’, and more than 1.3%-7.8% for ‘Jinmai 47’. The results indicated that, the granular flows helped the roots develop much faster and stronger although there was obvious difference among the variety of seeds. The average biomass was decreased and no significant difference of the stem length comparing the contrasts. Higher grain yield had been observed through the treatment by granular flows. The treatment of 120 W/h/kg group was the best. The treatment of 120 W/h/kg grains of ‘Changhan 58’ and ‘Jinmai 47’ increased 5.3% and 6.2% respectively than the control groups. There was obvious difference of effects on yield component among the two wheat varieties. Different dosages of granular flows would increase the photosynthetic rate of flag leaves during anthesis.
