大棚秋延后小型无籽西瓜定植密度对其产质量的影响

Effects of Planting Density on Yield and Quality of Greenhouse Autumn Delayed Mini Seedless Watermelon

[目的]探索大棚秋延后小型无籽西瓜的适宜定植密度。[方法]以小型无籽西瓜桂西瓜1号为试验材料,研究大棚秋延后小型无籽西瓜不同定植密度对其生育期、产量和品质的影响。[结果]不同定植密度对桂西瓜1号的生育期、品质影响不明显,但各处理间产量有差异,株距40 cm处理下产量最高,但商品果率最低,株距50 cm处理时产量与40 cm株距处理无显著差异,且商品果率高。[结论]在塑料大棚秋延后吊蔓栽培、单蔓整枝条件下,株距50 cm处理,即26 670株/hm2为最适宜定植密度。

[Objective] The aim was to explore suitable cultivating density of greenhouse autumn delayed mini seedless watermelon. [Method] With Guixigua No. 1 as test material,the effects of different cultivating density on growth period,yield and quality of greenhouse autumn delayed mini seedless watermelon were studied. [Result]The results showed that effect of different planting densities on the growth period and quality of mini seedless watermelon Guixigua No. 1 was not obvious,but there had differences in the processing production. Under 40 cm spacing in rows,the yield was highest while commodity fruit rate was lowest; under 50 cm spacing in rows,the yield had no significant difference with that in 40 cm,the commodity rate was high. [Conclusion] In delayed autumn plastic greenhouse,hanging single tendril cultivation and50 cm spacing in rows,the optimal cultivating density was 26 670 plants / hm2.
