红花不同定植密度对农艺性状的影响

Effect of Different Planting Densities on Agronomic Traits of Safflower

以新疆裕民1号为供试材料,设置6个不同定植密度处理,对红花不同密度下的农艺性状进行了分析,以探讨甘谷县红花适宜的种植密度。结果表明,随定植密度的增加,红花产量先升高、后降低的趋势,定植密度为1.6万株/667m^(2)时,农艺性状表现好,红花产量相对于其他处理亩产最高,相应总经济效益也最高,是63285.6元/hm^(2)。综上所述,红花裕民1号在甘谷县中等肥力上适宜的种植密度控制在为1.6万株667m^(2)。

In this experiment,the"Yumin No.1"safflower variety from Xinjiang was used as the test ma-terial.Six different planting density treatments were set up to analyze the agronomic traits of safflower under vari-ous densities.The objective was to explore the suitable planting density for safflower in Gangu County.The re-sults indicated that as planting density increased,the yield of safflower first increased and then decreased.When the planting density was 16,000 plants per 667 m^(2),the agronomic traits were optimal,and the yield per 667 m^(2) was the highest compared to other treatments.The corresponding total economic benefit was also the highest,reaching 63,285.6 yuan per hectare.In summary,the suitable planting density for"Yumin No.1"safflower in Gangu County,under medium fertility conditions,is 16,000 plants per 667 m^(2).
