摘要
杂交谷子高产、节水、优质,在河北省张家口市坝下地区表现出了显著的增产优势和增收效果,但现有品种不能在坝上地区正常成熟。为发挥杂交谷子的增产优势,提高坝上地区粮食作物产量,以张杂谷3号和张杂谷6号为试材,通过适时早播、覆膜和移栽等栽培方法,研究了杂交谷子在坝上地区的种植效果,旨为明确杂交谷子能否在坝上地区种植提供依据。结果表明:张杂谷6号露地直播平均产量为3 748.5 kg/hm2,较对照增产86.1%,经济效益显著。在小日期新品种成功选育前,作为过渡,可以在坝上地区露地直播张杂谷6号。
Hybrid millets have the advantages of high-yield, water-saving and good quality, which have brought good economic effect in Baxia area. However, present varieties might not ripen normally in Bashang area. In order to make clear the cultivation possibility of hybrid millets in Bashang area, hybrid millet Zhangzagu No. 3 and Zhangzagu No. 6 were studied, by early-sowing, film mulching and transplanting technologies. The results showed that the average yield of Zhangzagu No. 6 by outdoor direct seeding was 3 748.5 kg/hm2, 86. 1% higher than CK, which could bring great economic benefits. Before breeding new early-maturing varieties, Zhangzagu No. 6 could be suggested in Bashang area.
