【 摘 要 】

So as to study the effects of seed pelleting on the physiological characteristics of rice, took the japonica hybrid rice variety Tianlongyou 619 as the material, this experiment adopted different pelletized packaging materials and different sowing methods to test the physiological characteristics of rice at different growth stages under field cultivation conditions. Seen from The results, it showed that the soluble sugar content, soluble starch content, soluble protein content and peroxidase activity of the seed granulated rice were increased during the growth process, and the physiological indexes of rice in the T3 treatment (soil-to-fertilizer mass ratio was 100:1) increased the most. The seeding method of 4 seeds per hole was the most effective to improve the physiological characteristics of rice. The granulation of seed-pelleting and the seeding method with 4 seeds per hole have some advantages for the direct cultivation of northern japonica rice.
