北京蔬菜生产"三率"测算分析
Calculation and Analysis of the"Three Rates"of Vegetable Production in Beijing
摘要
Abstract
By calculating and analyzing the current situation of land output rate,labor productivity,and resource utilization rate of 7 types of vegetables in Beijing,called"three rates"for short,this study analyzed the production and resource utilization of various types of vegetables,by comparing with large and medium-sized cities nationwide,the dominant varieties and the varieties to be developed in Beijing vegetable production were identified.The research showed that the dominant vegetable is facility tomato,with two types of relatively advantageous vegetables,namely open field eggplant and facility eggplant.There are four types of vegetables to be developed,namely facility pepper,open field Chinese cabbage,facility cucumber,and open field cucumber.Among them,facility tomato has a higher planting level,while open field eggplant and facility eggplant have relative planting advantages.Facility cucumber has certain potential for yield improvement;comparing the"three rates"of facility vegetables and outdoor vegetables,it was found that except for the utilization rate of agricultural film,the"three rates"of facility vegetables were significantly higher than those of outdoor vegetables;compared with large and medium-sized cities nationwide,the utilization rate of agricultural film is mostly lower than the average level of large and medium-sized cities nationwide.Based on this,suggestions were put forward to improve the"three rates"of vegetable production in Beijing from three aspects:increasing the multiple cropping index,strengthening training,and promoting green production.关键词
