小农户模式下不同播期和播量对冬小麦群体动态和产量的影响

Effects of Different Sowing Date and Seeding Rate on Population Dynamic and Yield of Winter Wheat Under Smallholder Mode

为探索曲周地区小麦的最佳播期和播量,本文对示范区59个农户进行跟踪调查研究。结果表明,在10月10日播种、播量为225 kg/hm^(2)时,小麦有效穗数最多,产量最高。应注意小麦播期推迟时,适当增加播量,以保证产量。

In order to explore the best sowing date and seeding rate of wheat in Quzhou area,this paper investigated 59 farmers in the demonstration area.The results showed that the effective panicles number and yield were the highest when sowing date was October 10 and seeding rate was 225 kg/hm^(2).It should be noted that when the sowing date of wheat is delayed,the seeding rate should be increased appropriately to ensure the yield.
