随着上海蔬菜产量、产值的不断提高,菜田施肥量,特别是化肥的使用量也不断增加。为了掌握目前上海菜区的施肥水平,指导菜农科学施肥,保持蔬菜生产的持续发展,上海市蔬菜科学技术推广站会同金山、南汇、青浦等10个区县蔬菜技术推广站的有关科技人员,对本市郊区20个乡镇的30个地块,共59.37hm~2菜田的施肥情况进行了调查研究,并作了初步分析评估,为指导菜区合理用肥提供依据。 With the continuous improvement of vegetable production and output value in Shanghai, the amount of fertilizers in vegetable fields, especially the use of chemical fertilizers, has also been on the rise. In order to grasp the current fertilization level in Shanghai vegetable zone and guide the farmers and peasants to apply fertilizers and maintain the sustainable development of vegetable production, Shanghai Vegetable Science and Technology Promotion Station cooperates with relevant scientific and technical personnel of vegetable technical extension stations in 10 districts and counties including Jinshan, Nanhui and Qingpu, The survey on the fertilization of 59.37hm ~ 2 vegetable fields in 30 plots in 20 townships in the suburbs of the city was conducted and preliminary analysis and evaluation were conducted to provide basis for guiding the rational use of fertilizers in the vegetable areas.
