摘  要:
为了确定饲用甜高粱地标3号制种母本适宜播种期,进行了不同播种期对其农艺性状、产量和效益影响的研究。结果表明,随着母本播种时间的延后,籽粒性状和产量呈现先升后降的趋势;其它农艺性状呈递减趋势。母本不同播种期产量、产值、利润和投资效率变化的顺序是:4月26日>4月22日>4月30日>5月4日,适宜播种时间一般为4月22日至4月26日,最佳播种时间为4月26日。

摘  要:
In order to determine the proper sowing time of female parent for seeds production of forage sweet sorghum Dibiao 3,the impact test of female parent's sowing time on its agronomic traits,yield and benefits was conducted.The results revealed that the grain character and yield showed a trend of increasing first and then decreasing,meanwhile,the other agronomic traits of the forage sweet sorghum declined with sowing time of female parent prolonged.The order of yield,output value,profit and investment efficiency with different sowing dates of female parent was:April 26 th > April 22 nd > April 30 th >May 4 th.The suitable sowing time of the female parent was from April 22 nd to April 26 th,and the best sowing time was April 26 th.
