| Abstract: | Different sowing days, planting densities and applied pure N - fertilizers for corn Chengdan NO. 13 were studied. The results showed that high - yield physiological index correlated significantly to cultivative techniques and economic index. The high stable yield coefficient analysis revcaled that Chengdan NO. 13 is a variety which is of high and stadlc yields through Sichuan distribution experiments in 1989~1990 and variety experiments in 1992~1993. |
