目前,大棚番茄生产群体结构变化很大,栽培密度由每亩2,800株增到4500株;整技方式有留2—4穗果的单、双干早熟栽培,也有留5—9穗果的单干一茬到底栽培;栽培方式有垄作、畦作和间作、主副行栽种。上述诸方面都涉及到群体结构布局问题。研究大棚番茄群体结构、空间布局、使其达到科学性,可提高番茄植株对光能的利用率,高效率地利用空间和地力,为早熟丰产奠定丰富的物质基
At present, the structure of greenhouse tomato production groups vary greatly, planting density increased from 2,800 to 4,500 per acre; the whole way to stay with 2-4 spike fruit single and double dry early cultivation, there are also left alone 5-9 spike Cultivation in the end of a crop; cultivation methods are ridge, cropping and intercropping, the main line deputy planted. All these aspects involve the issue of group structure layout. To study the structure and spatial distribution of tomato population in greenhouse can make it scientific. It can increase the utilization of light energy of tomato plants, make efficient use of space and fertility, and lay a rich material base for early maturing high yield
