【摘要】 在深圳市郊某蔬菜基地进行了小白菜、菜心的硝酸盐积累试验,采用统计分析类数据挖掘技术对田间栽培、光照、施肥技术、采收时期等因素进行了研究分析,在16种处理方案中,筛选出4种适宜无公害蔬菜的栽培模式,研究发现对蔬菜硝酸盐积累影响显著的因子依次为日照、采收时期、追肥次数和基肥比例,研究结果对抑制蔬菜中的硝酸盐积累提供了依据。

【Abstract】 In present study, nitrate residue analysis for Chinese cabbage was conducted at a vegetable-base in Shenzhen suburbs. In the experiment factors of cultivation management, lighting, fertilization and harvesting time were analyzed with data-mining technology of statistical analysis. Among the 16 experimental designs, 4 cultivation modes were selected for pollution-free vegetable production. The experiment results showed that lighting, harvesting time and fertilization frequency and ratios were very important factors in order of affecting nitrate accumulation.In addition, the experiment results supplied data basis for nitrate accumulation control for vegetable production.
