播期、播量和施氮水平对‘西农109’小麦生长及产量的影响

Effects of Sowing Date, Sowing Amount and Nitrogen Application Level on Growth and Yield of Wheat ‘Xinong 109’

对在陕西省和安徽省审定的冬小麦品种西农109进行栽培技术措施探索,为其在关中地区乃至黄淮南片冬麦区的推广提供技术支撑。试验于2018-2020年在陕西省宝鸡市陇县的西北农林科技大学旱地农作物试验示范基地开展,通过探索不同播期、播量以及氮肥水平处理条件下对冬小麦西农109农艺性状和产量及品质的调控影响,综合分析得出:10月10日播种、157.5 kg/hm~2的播量与144~168 kg/hm~2氮肥水平栽培措施更适宜西农109小麦增产提质。

In this paper, the cultivation techniques and measures for winter wheat variety Xinong 109 approved by Shaanxi and Anhui provinces were explored to provide technical support for its extension in Guanzhong area and even in the South Huanghuai winter wheat area. The experiment was carried out in Crop Experiment and Demonstration Base of Northwest A&F University in the dry land area of Longxian county in Baoji of Shaanxi Province from 2018 to 2020. Through study on the regulatory effects of different sowing dates, sowing amounts and nitrogen fertilizer level treatment on the agronomic traits, yield and quality of Xinong 109, we found that 10 th October( 10 days later than the normal sowing date),sowing amount of 157.5 kg/hm~2 and nitrogen fertilizer level of 144-168 kg/hm~2 are more suitable for increase of yield and quality of Xinong109.
