摘要
[目的]研究沙坡头区种植二茬春小麦的适宜性.[方法]以宁春4号为供试小麦品种,分别于2015年7月13日和17日播种,研究不同播种期对宁春4号生育期、苗情、经济性状及产量的影响,并与历年参数进行比较,评价种植二茬春小麦的适宜性.[结果]宁春4号的全生育期为73~77 d,基本苗数在200万株/hm2以上,千粒重22.10~23.15 g,理论产量2 625~2 730 kg/hm2,但是大部分指标较历年减少.[结论]结合经济成本、田间管理,推断沙坡头不适宜推广种植二茬春小麦.
Abstract
[Objective]To study the suitability of two spring wheat planted in Shapotou Area. [Method]Taking Ningchun 4 as tested wheat varieties, sowing in July 17th and July 13th, 2015, effect of different sowing stage on the growth period, seedling growth, yield and economic characters were studied. Compared with the parameters in the past year, the suitability of two spring wheat was evaluated. [Result]Total growth period of Ningchun 4 was 73 to 77 d, the basic seedling number was more than 2 million plant/hm2, 1 000 grain weight was 22.10~23.15 g, theoretical yield was 2 625~2 730 kg/hm2, but most of the indexes was reduced over the years. [Conclusion]Combined with economic cost and field management, it was concluded that two crops of wheat were not suitable for popularizing in Shapotou Area.
