高寒地区番茄不同栽培密度对产量的影响

Effect of Different Planting Density on the Yield of Tomato in Alpine Region

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。

Taking ‘Zhongyan 988F1’ tomato as test material, the effect of different planting density on the yield and agrinomic traits in alpine region were studied, by using the experiment of two factors and four levels of density. The results showed that two factors of row spacing and plant spacing interaction effects had no significant difference, spacing between the difference reached significant level;tomato plant under the two kinds of density with （80-40） cm× 35 cm and （70-40） cm× 35 cm performance better overall traits, yield was relatively high. The difference of yield was significant level. They were the reasonable density of greenhouse tomato cultivation in alpine region.
