日光温室番茄长季节栽培定植密度和温室部位与产量产值的相关性

The Relativity between Fruit Yield and Value and Different Parts in Solar-greenhouse and Different Planting Densities in Long-term Growing Tomato in Solar Greenhouse in North China

于2005年至2006年,以无限生长型番茄品种卡特琳娜为试材,在三个不同栽培密度下,研究了日光温室内不同部位长季节栽培的番茄植株生长发育及果实品质和产量的关系。结果表明,定植密度对番茄产量及果实品质的影响非常大,并且对冬春季果实的坐果率和单果重影响也很大。不同的部位对植株生长发育和产量的构成影响很大。在本实验条件下,北方地区番茄长季节栽培在日光温室内不同部位的最适定植密度是不同的。综合比较产量、果实单果重、产值等方面,整个温室最适宜的平均栽培密度为80 cm×50 cm×46cm,其中温室南部最适宜的栽培密度为80 cm×50 cm×40 cm。

The solar greenhouse test in 2005～2006 with unlimited growing tomato variety Ketelinna under 3 planting densities showed that the planting density had great effects on tomato yield and fruit quality as well as on fruit setting rate and single fruit weight in winter and spring.The different parts had great effect on the growth and development of plant and yield constitutes.Under this test condition,the most suitable planting density of the cultivation was different in different parts in solar-greenhouse in northem China. Comparing comprehensively on yield, single fruit weight and production value, the most suitable planting density was 80 cm × 50 cm ×46 cm, and the most suitable cultivation density in the south of greenhouse was 80 cm × 50 cm ×40 cm.
