优质杂交稻江优126不同丢秧密度试验研究

Study of Different Throwing Density on High Quality Rice Jiangyou 126

为探索适宜优质杂交稻江优126的抛秧密度,开展了5个密度的研究。结果表明:密度1.6万/667m^2穴单产最高,达728.41kg/667m^2;其次是密度1.8万穴/667m^2,单产701.46kg/667m^2;1.4万/667m^2穴单产为694.79kg/667m^2,密度1万穴/667m^2和1.2万穴/667m^2单产较低。经综合分析江优126采用丢秧最佳密度为1.4-1.8万穴/667m^2。

To explore planting density of high quality rice Jiangyou 126 by throwing,5 densities were tested. The results showed that the yield of 16000 hills/667 m^2 was greatest,it＇s 728. 41 kg/667 m^2,yield of 18000 hills/667 m^2 was second,it＇s 728. 41 kg/667 m^2,and then fallows 16000 hills/667 m^2,the yield was 694. 79 kg/667 m^2,the yield of 10000 hills/667 m^2 and 12000 hills/667 m^2 were lower than above densities. So the planting density of 14000-18000 hills/667 m^2 were proposed on transplant seedling by throwing.
