Effects of Different Rate of Seeds on the Seedling Quality and Yields of Rice in the Saline-Sodic Fields

doi:10.7668/hbnxb.2011.S2.016

Abstract

Abstract: Seeding quality and yields of DongDao2 in the Saline-Sodic were investigated respectively.The results showed that different rate of seeds affected seedling quality significantly.With seeds rate increased,seedling quality declined.50,80,100,120 g seeds rate per seedling tray was significantly better than 150 g and 200 g,whose seedlings grew well and had higher quality.Yields rose at first and then decreased with the increasing of seeds rate.80 g(500 g/m²) seeds rate per seedling tray had the maximum yields of 5 284.7 kg/ha,which was 9.9%,6.1%,9.8%,16.1% and 14% higher than 50,100,120,150,200 g respectively.

Key words: Rice, Different rate of seeds, Seedling quality, Yield
