- 摘要:
- 为确定陕西省主栽品种榆糜2号引种到黑龙江省西部干旱区的最佳种植时间,以榆糜2号为试验材料,设置5月8日(B1)、5月18日(B2)、5月28日(B3)、6月7日(B4)、6月17日(B5)5个播期,在黑龙江省绥化管局和平牧场开展大田试验,比较不同处理下榆糜2号成熟期株高、主穗长、主茎节数、单穗粒数、千粒重和产量的变化。结果表明:B1、B2、B3处理的榆糜2号在株高、主穗长、主茎节数、单穗粒数、千粒重等指标上均高于B4、B5处理的糜子;各处理中榆糜2号的产量以B1处理为最高,分别较B2、B3、B4和B5处理高7.41%、8.33%、28.70%和19.44%。从而得出结论,榆糜2号在黑龙江省西部干旱区于5月8日播种可以获得较高的产量。
- Abstract:
- In order to determine the best sowing date of Yumi 2 that mainly plants in Shaanxi province in the arid area in western Heilongjiang province,the plant height,main spike length,main stem nodes,grains per spike,1 000-grain weight and yield of Yumi 2 were measured under different sowing dates treatments,that were May 8th (B1),May 18th(B2),May 28th (B3),June 7th(B4),June 17th (B5)in Heilongjiang Province.The results showed that the treatments of B1,B2 and B3 were higher than those of B4 and B5 in the plant height,main spike length,main stem nodes number,grain number per spike and 1 000-grain weight.The yield of B1 was higher than that of B2,B3,B4 and B5,and the yield was higher than that of B2,B3,B4 and B5,7.41%,8.33%,28.70%,19.44%.Based on the above traits,it is concluded that the appropriate sowing date of Yumi 2 can be on May 8th in the arid area of western Heilongjiang province so as to get more yield.
