摘要
为了解山西省设施蔬菜生产存在的问题,对8个代表区域设施蔬菜生产的投入产出情况进行了调查,并分析了生产投入构成、投入产出关系及生产要素与产出的关系。结果表明,日光温室相对拱棚具有高投入、高产出的特征,区域间设施蔬菜投入产出差异较大;随投入的增加产出增加幅度减小。在种苗、整地、肥料、灌溉、病害防治、棚室维护等6项投入中,肥料投入比例最大,要素投入增加均会促进产出增加。总之,山西省设施蔬菜生产缺乏标准,需要规范各项生产要素投入使之达到科学合理的要求,最终实现标准化,以提高山西省设施蔬菜的生产效益。
In order to solve the problems existing in protected vegetable production in Shanxi province, The investigation on the input-output of the production of protected vegetable in eight representative regions was made, and the composition of production input, the relation between input and output, and the relation between production factors and output were analyzes. The results show that the sunlight greenhouse possesses the features of higher input and higher output compared to the arched shed, and the difference of the input-output of protected vegetable among different regions is greater; and the increase amplitude of the output decreased with the increase of the input. In six input items of seedlings, site preparation, fertilizer, irrigation, disease control and arched shed maintenance, the input proportion of fertilizer was the largest, and the input increase of all factors will help to increase the output. In conclusion, Shanxi Province lacks the standards for the production of protected vegetable, needs to standardize the various factors of production input for achieving the scientific and reasonable requirements, and finally realizes the standardization and improves the production benefit of Shanxi’s protected vegetable.
