摘要
[目的]探究种植密度对薏苡生长及产量的影响。[方法]以薏农种植密度2.780万穴/hm2为对照,并采用4个不同密度,即2.085、2.780、3.126和4.169万穴/hm2进行田间小区试验。[结果]种植密度对薏苡产量有很大的影响。从各试验处理结果看,在栽培中,以窝行距30 cm×80 cm,即4.169万穴/hm2为最好,产量比对照增产37.36%;其次是窝行距60 cm×80 cm,即2.085万穴/hm2,产量比对照增产16.45%。[结论]试验考察了种植密度对薏苡生长及产量的影响,为薏苡高效、高产、高质栽培提供理论依据。
[Objective] To study effects of planting density on growth and yield of SEMEN COICIS.[Method] With planting density of 2.780×104 caves/hm2 as control,four densities of 2.085,2.780,3.126 and 4.169×104 caves/hm2 were adopted to conduct field experiment.[Result] Planting density has significant effects on yield of SEMEN COICIS.Seeing from the results,row wide 30 cm×80 cm,namely 4.169×104 caves/hm2 is the best,the yield increased 37.36% compared with control;row wide 30 cm×80 cm,namely 2.085×104 caves/hm2 take the second place,the yield increased 16.45%.[Conclusion] Effects of planting density on growth and yield of SEMEN COICIS were investigated,which provide theoretical basis for high-efficient,high-yield,high-quality cultivation of SEMEN COICIS.
