为探讨黑龙江西部半干旱地区小豆高产高效栽培技术措施,采用裂区设计,在平播、65cm垄作、110cm垄作方式下,研究9、13、17、21、25万株/hm~2密度对小豆子粒产量及干物质积累动态的影响。结果表明,不同种植方式的单株荚数和单株粒数均在9万株/hm~2时最高,110和65cm垄作主茎荚数随密度增加呈降低趋势;相同种植方式下,不同密度处理对小豆百粒重的影响较之对其他性状(分枝数除外)稍小,不同种植方式随密度增加小豆茎叶干物质积累量呈现先上升后下降的趋势,小豆荚和子粒干物质积累量随生育进程呈上升趋势。平播和65cm垄作在17万株/hm~2时小豆产量最高,分别为1 387.67和1 723.53kg/hm~2;110cm垄作条件下,21万株/hm~2时小豆产量最高,为1 901.07kg/hm~2;故黑龙江西部半干旱地区110cm垄作,密度21万株/hm~2为小豆适宜种植模式。
In order to explore the high yielding and efficient cultivation techniques of adzuki bean in the semiarid area of western Heilongjiang Province, we studied the effects of densities of 9, 13, 17, 21, 25, 000 plants / hm ~ Effects of grain yield and dry matter accumulation dynamics. The results showed that the number of pods per plant and the number of single plant per plant were the highest at 90 000 plants / hm -2, and the number of stem pods of 110 and 65 cm ridge decreased with the increasing of density. Under the same planting pattern, Compared with other traits (except the number of branches), the effect of treatment on the weight of adzuki bean was slightly smaller. The dry matter accumulation of adzuki bean increased at first and then decreased with the increasing of density. The dry matter accumulation of adzuki bean and grain The amount increases with the growth process. The yield of adzuki bean was highest at 170000 plants / hm ~ 2 with flat planting and 65cm ridge planting, respectively, which was 1 387.67 and 1 723.53kg / hm ~ 2, respectively. 901.07kg / hm ~ 2. Therefore, 110cm ridge planting in the semi-arid area of western Heilongjiang Province with a density of 210,000 plants / hm ~ 2 is suitable for planting.
