冀西北坝上地区大蒜播种期研究

为了探讨冀西北坝上地区大蒜适宜的播种期,给当地大蒜高效生产提供理论依据,试验以大蒜品种西八里为试验材料,设置A(3月22日)、B(4月1日)、C(4月11日)3个不同播期,测定了不同播期下大蒜的生育期、植株性状、蒜头性状、蒜薹和蒜头产量等指标。结果表明,播期B和C较播期A的出苗时间分别缩短7 d和11 d;播期B的植株性状、蒜头性状均优于播期A和C,播期B一级蒜的比例最高,较播期A、C分别高出11.0和27.6个百分点;播期B较播期A和C的蒜薹产量分别提高8.41%和40.82%,蒜头产量分别提高10.19%和16.08%。本试验条件下,坝上地区大蒜适宜的播种期为3月底至清明节之间。

Study on Sowing Time of Garlic in Bashang Region in the Northwest of Hebei Province

In order to explore the suitable sowing time of garlic named "Xibali" in Bashang region in the Northwest of Hebei Province,so as to provide a reasonable foundation for the local garlic production,the three sowing time treatments including A (March 22), B (April 1), C (April 11) were designed to determine the indexes including growth and development period, plant trait,bulb traits and yield, et al. The results showed that, compared with treatment A, the emerging time of treatment B and treatment C was shorten 7 and 11 days,respectively. The plant trait,bulb traits of treatment B were significantly higher than treatment A and treatment C;The premier grade garlic proportion of treatment B was the highest, which was 11.0 per-centage point and 27.6 percentage point higher than treatment A and treatment C, respectively. Compared with treatment A and treatment C, the garlic bolt yield of treatment B was increased by 8.41℅ and 40.82℅,the garlic bulb yield of treatment B was increased by 10.19℅ and 16.08℅,respectively. In this experiment,the suitable sowing time of garlic in Bashang region in the Northwest of Hebei Province was the end of March to Qingming Festival.
