【摘要】 试验结果表明,参试各品种之间生育进程有较明显差异,同期播种同类品种采收间隔时间4d以上,同一品种不同播期采收间隔时间16～22d,早、中、晚熟品种搭配和分期播种结合,使青嫩鲜穗采收期达到53d,比单一品种采收期增加40d左右。更多还原

【Abstract】 The experimental results showed t h at there are more obvious differences in the course of development between all v ari-eties tested,the harvest interval time of congeneric varieties sowing at t he same time is beyond4days,and the harvest interval time of i-dentical varie ty sowing at different time is between16and22days,moreover,through the com bination of premature,mid-mature and late-mature varieties arrangement in gro ups and sowing at different seed time,the harvest time of tender and fresh ears may arrive at53days,which is more about40days than that of single variety .更多还原
