以“中研988F1”番茄为试材,通过二因素四水平密度处理,研究了高寒地区不同栽培密度对大棚番茄植物学性状和产量的影响,筛选出适宜西宁地区大棚栽培番茄的合理密度。结果表明:行距与株距二因素互作效应无显著差异,株距间差异达显著水平;在8种密度试验中(80-40)cm×35cm和(70-40)cm×35此2种密度下栽培的番茄植物学性状综合表现较好,小区产量相对最高,且与其它小区产量间达差异显著水平,是高寒地区大棚番茄栽培的合理密度。 With “Zhongyan 988F1” tomato as test material, the effects of different planting densities on the growth and yield of tomato in greenhouse were studied by two factors and four horizontal densities, and the reasonable density of tomato suitable for growing in greenhouse in Xining was screened out. The results showed that there was no significant difference in the two-factor interaction effect between row spacing and plant spacing, and the difference between plant spacing was significant. Under the two density densities (80-40 cm × 35 cm and (70-40) cm × 35) The cultivated tomato had a better performance of botany traits, the highest yield of plots and the significant difference with yield of other plots, which was the reasonable density of tomato cultivation in greenhouse in alpine region.
