不同栽培密度与留果数对秋大棚番茄生长发育及产量的影响

为提高北京地区秋大棚番茄产量,增加效益,找出一种设施蔬菜高效种植模式,本试验采用裂区试验设计,以产量为第1考核指标,研究了不同栽培密度与单株留果数对秋大棚番茄生长发育及产量的影响。结果表明,不同的栽培密度对番茄植株生长前期影响较小,对生长后期有显著影响。不同栽培密度与单株留果数对番茄产量和平均单果质量的影响均有显著差异,当栽培密度为3200株/667m2、留果数为14个/株时,产量最高,可达5375.2kg/667m2。

Effects of the Different Plant Density and Different Stay Fruit on Growth Vigour and the Yield of Autumn Greenhouse Tomato

A model of efficient cropping practices is found to promote quanlities of autumn greenhouse tomatoes in Beijing municipality,and to increase economic incomes in turn.The split-plot experimental design is used in this test,production is as the first evaluation indicators to study different plant density and stay-fruit number per plant effects of growth and yield of autumn greenhouse tomatoes.The results shows that,different planting density is smaller impacts of early growth than later of it,overall,differen...
