春大棚保护地栽培条件下,研究了处理1为2500株/667m2、处理2为2700株/667m2、处理3为2900株/667m2、处理4为3100株/667m2、处理5为3300株/667m2和处理6为3500株/667m26个密度处理对黄瓜植株生长势、产量及效益的影响。结果表明,不同密度对春大棚黄瓜植株的株高、叶片数影响不大,对叶面积有一定的影响,在本试验的6个处理中,除处理4叶面积显著>处理2、6外,其他处理间差异不显著,且各处理与对照相比差异不显著;对产量有显著的影响,以处理5产量最高,达到4628.5kg/667m2,比对照增产24.2%,与产量相关联的,以处理5效益最高,达到5398.73元/667m2,比对照增加1078.28元/667m2,增效达到25%。试验初步结果表明,京郊春大棚刺黄瓜生产的适宜密度为3300株/667m2。
Under the greenhouse cultivation conditions, the treatment 1 was 2500 plants / 667m2, the treatment 2 was 2700 plants / 667m2, the treatment 3 was 2900 plants / 667m2, the treatment 4 was 3100 plants / 667m2, the treatment 5 was 3300 plants / 667m2 and the treatment 5 was 3300 plants / The effect of treatment 6 on the growth vigor, yield and benefit of cucumber plants was 3500 / 667m26 density treatment. The results showed that different densities had little effect on plant height and leaf number of cucumber in spring greenhouse and had a certain impact on leaf area. In the six treatments of this experiment, in addition to 4> There was no significant difference among the other treatments, and there was no significant difference between the treatments and the control. There was a significant effect on the yield, with the highest yield of 4628.5kg / 667m2 and the yield of 24.2% Treatment 5 has the highest benefit, reaching 5398.73 yuan / 667m2, an increase of 1078.28 yuan / 667m2 compared with the control, with a gain of 25%. Preliminary results showed that the suitable density of prickly cucumber production in spring in Beijing suburbs was 3300 plants / 667m2.
