为了研究播种期和密度对荞麦产量性能的影响，选用甜荞麦品种吉乌1号，设计了5个播种期，分别为5月5日、5月25日、6月14日、7月4日和7月24日以及三个播种密度，即36、45和54万株·hm-2。测定了株高、主茎节数、主茎分枝数、植株鲜重和干重、株粒数、千粒重和产量等指标。结果表明，播种期和播种密度显著影响甜荞麦产量及产量相关性状。吉乌1号在黑龙江省西部地区的适宜种植密度为54万株·hm-2，适宜种植播期在6月14日~7月4日。

In order to study the effects of sowing date and planting density on productivity of sweat buckwheat,the cultivar Jiwu1 was used in field experiments. The experiment was designed in a split-split plot with randomized complete block design in three replications. The main plots were sowing date including 5 may,25 may,14 june,4 july and 14 july. Subplots were three planting densities of 3.6×105,4.5×105 and 5.4 ×105 plant·hm-2. The plant height,Node number,branching,fresh weight of plant,dry weight of plant,thousand grain weight and yield were measured in this experiment. The results showed that the sowing date and plant density produced the significant effects on the yield components and yield of sweat buckwheat. The optimum sowing date for Jiwu1 was from 14 june to 4 july,and the optimum planting density was 5.4×105 plant·hm-2 in the west of Heilongjiang province.
