摘要
以耐裂王番茄为材料,设置5种栽培密度处理,通过测定分析不同栽培密度下,番茄群落中下部光照强度、光质组成、番茄产量及果实品质等指标,研究不同栽培密度对四川盆地番茄产量和品质的影响。结果表明,降低栽培密度可以增加番茄群落中下部的光照强度、降低远红光占比,增加了红光、绿光及蓝光占比;同时提高番茄单果质量、单株产量、可溶性糖和维生素C含量等指标。1667株·667 m^(-2)处理下番茄单株产量、果实可溶性糖和维生素C含量分别比2779株·667 m^(-2)处理提高45.34%、37.11%和84.62%。综上所述,在四川盆地667 m^(2)种植1667~1852株番茄可显著提高单株产量和品质,试验结果为田间生产实践提供了理论依据。
Five cultivation densities were tested using tomato variety Nailiewang.By measuring light intensity,light quality,tomato yield and fruit quality in the middle and lower parts of tomato under different plant densities,the effect of plant density on tomato yield and quality in the Sichuan Basin was studied.The results showed that decreasing planting density increased the light intensity in the middle and lower parts of the tomato plant,reduced the proportion of far-red light,and increased the proportion of red light,green light and blue light,increased fruit weight,yield per plant,soluble sugar and vitamin C content.Yield per plant,fruit soluble sugar and vitamin C content for planting density of 1667 plants per 667 m^(2) were 45.34%,37.11%and 84.62%higher than those of 2779 plants per 667 m^(2).In conclusion,1667-1852 plants per 667 m^(2) in the Sichuan Basin can significantly improve the yield per plant and quality of fruit.
