摘　　要：为明确不同种植密度对黄瓜新品种‘津优401’植株生长、瓜条商品性及产量的影响,试验采用春露地栽培,在同等土壤肥力条件下,设置4个不同667 m2栽培密度(2 000、2 400、2 800、3 000株),调查植株生长各指标,记录和统计商品瓜产量及总产量。结果表明:不同密度处理对植株生长发育没有明显的影响,但对瓜条商品瓜产量和总产量有极显著影响。667 m2栽培密度为2 400株时,该品种有效产量和产值都达到最高,是该品种在该地区的最佳栽培密度。The objective of the study is to clarify the effect of plant density on cucumber plant growth, fruit quality and yield of the new variety ‘ Jinyou 401 ＇. 4 plant density levels including 2 000,2 400,2 800 and 3 000 plants per 667 m2 were adopt- ed in the experiment. Plant growth parameters, marketable fruit yield and total fruit yield were observed and analyzed. The results showed that there were no obvious difference in plant hight, stem diameter, leaf number, nod position of 1st female flower and the 1st harvesting time. But there were significant difference in total yield and marketable fruit yield. The results suggest that the optimum plant density for cucumber＇Jinyou 401 ＇in Luoyang region is 2 400 plants per 667 m2.
