不同播期和播量对济宁17号小麦品种产量的影响

Effect of different Sowing Date and Sowing Amount on Yield of Wheat Variety Jining No. 17

不同播期和播量对小麦品种济宁17号的产量构成及产量有不同的影响。播期对济宁17号的产量影响很大,不同播期调播量可以使济宁17号小麦群体达到合理的群体结构,但播期处理对济宁17号小麦群体结构的影响比播量处理对群体结构影响更大,因此研究济宁17号小麦不同播期、播量对其产量的影响可以确定其最佳播期为10月5日—15日;适宜播期内播量以基本苗12×10^(4)~20×10^(4)苗/hm^(2)为宜,以播期调播量。

Different sowing date and amount had different effects on the yield composition and yield of wheat variety Jining No.17.The sowing date has a great impact on the yield of Jining No.17. Adjusting the sowing rate at different sowing dates can make the population structure of Jining No.17 wheat reach and reasonable, but the effect of sowing date treatment on the population structure of Jining No.17 wheat is greater than that of sowing rate treatment. Therefore, the best sowing date can be determined as October 5 ~15 by studying the effect of different sowing dates and sowing rates on the yield of Jining No.17 wheat. The suitable sowing amount within the suitable sowing time is 12×10^(4)~20×10^(4)sprout/hm^(2)of basic seedlings, and the sowing amount is adjusted according to the sowing time.
