塑料大棚是陇东地区，特别是泾河川区蔬菜栽培的主要设施。因地制宜安排塑料大棚蔬菜栽培模式，对优化泾河川区蔬菜品种布局、减轻连作障碍，进而提高土地产出效益具有现实意义。根据近年的试验和生产实践，总结出3种适宜泾河川区应用的塑料大棚蔬菜“春提早、秋延后”栽培模式，即“一年一大茬”“早春一小茬-夏秋一大茬”“早春一大茬-夏秋一小茬”。对3种栽培模式的品种选择、茬口安排、栽培要点、产出与效益等进行了简要分析和评价。

Plastic greenhouses are the main facilities of vegetable cultivation in Longdong region, especially irrigation region along the Jing River. Suitable vegetable cultivation mode in plastic greenhouse based on local conditions has practical significance for optimizing the layout of vegetable varieties, reducing continuous cropping obstacles, and improving land output efficiency for irrigating region along the Jing River. According to the experiments and production practices in recent years, three cultivation models of 'early sowing in spring, late sowing in autumn per year' for plastic greenhouses were summarized, namely, 'planting one time per year with longer growth period', 'sowing two times per year, firstly sowing in early spring with shorter growth date, secondly planting in summer-autumn with longer growth date', conversely, 'on the first time sowing in early spring with longer growth date, on the second time sowing in summer-autumn with shorter growth period'. The variety selection, crop arrangement, key techniques of cultivation, output and benefit of three cultivation models were briefly analyzed and evaluated.
