摘要
为了探索不同种植密度与配置方式对藜麦Chenopodium quinoa农艺性状及籽粒产量的影响,2020年4—8月,在浙江省庆元县油茶Camellia oleifera幼林地,以‘陇藜1号’为试验材料,在行距为20~60 cm,株距为20~40 cm条件下,布设9种不同株行距配置方式的比较试验。结果表明,随着行距的缩小,藜麦的第1有效分枝部位上移,有效穗数减少,株高、主穗长、植株保存率、处理产量、抗倒伏性能提高;扩大株距,第1有效分枝部位下移,有效穗数、单株粒质量增加,主穗长、植株保存率、处理产量减少。在9个处理中,20 cm×20 cm株行距配置方式,能获得最高的单位面积藜麦产量。在试验当地,与‘陇藜1号’农艺性状相近的藜麦品系种植时宜适当密植,种植密度宜控制在160000~250000株·hm^(-2)。
In March 2020,oil tea base was established in Qingyuan,Zhejiang province with 1-year Camellia oleifera‘Changlin 53,4,27’with density of 1333 plant/ha.In April 2020,interplanting of Chenopodium quinoa‘Longli 1’was implemented in oil tea plantation with 9 densities and in August 2020,investigations were carried out on agronomic traits,lodging rate and seed yield.The results showed that the treatment with spacing of 20 cm×20 cm had the advantages of higher first effective branch,less number of productive ear,as well as improved plant height,main panicle length,survival rate,lodging resistance performance and the highest seed yield among the 9 treatments.Density with 160000-250000 plant/ha was recommended for interplanting of Chquinoa‘Longli 1’in Qingyuan.
