摘  要:
[目的]研究耐密植品种黔兴201的适宜密度。[方法]通过田间试验,设置6个不同的种植密度,考察密度对黔兴201和会单4号2品种产量和植株性状的影响。[结果]产量与密度间呈一元二次抛物线关系;对于2个品种,千粒重与密度均呈极显著负相关(P<0.01),穗长、穗行数与密度均呈显著负相关(P<0.05);对于黔兴201,单株有效穗数、果穗长与密度均呈显著负相关(P<0.05)、果穗粗与密度呈极显著负相关(P<0.01);对于会单4号,行粒数与密度呈极显著负相关(P<0.01)。[结论]黔兴201在贵州省西部以及云南省海拔1 400~2 550 m区域推广应用前景较好。

摘  要:
[Objective] The research aimed to study the suitable planting density of the compact planting variety Qianxing 201.[Method] The influences of density on the yield and plant character of Qianxing 201 and Huidan 4 were studied with the field experiment and six levels of planting density.[Results] The results showed that the relation between yield and planting density accorded with one-place quadratic.For Qianxing 201 and Huidan 4,it was a significant negative correlation between the 1 000-grain weight and density(P<0.01) and there was a significant negative correlation between ear length,ear rows and density(P<0.05). [Conclusion] There was a promising prospect for commercial production of Qianxing 201 in Guizhou province and the 1 400~2 550 m elevation area of Yunnan province.
