Effects of Different Sowing Rate on Matrix Raising Seedling Quality and Yield of Machine Transplanted Rice

The effects of different seed sowing rates on Kejie matrix material raised rice seedling growth and yield of Wuyunjing 23 were investigated in field experiment. The results indicated that there were larger differences for seedling traits of aboveground and un-derground in different seed sowing rates, the chlorophyll content, twine forces and root vigor were increased when the sowing rate was120 ~210 g/disc. The optimum sowing rate was 150~180 g/disc, which conducive to foster strong seedling and high yield.
