| 摘 要： | 在深圳市郊进行了小白菜、菜心的硝酸盐积累田间试验，采用统计分析类数据挖掘技术对田间栽培、光照、施肥条件、采收期等因素进行了研究分析。研究发现，在一定的氮肥水平条件下，对蔬菜硝酸盐积累影响显著的因子依次为光照、采收时期、追肥次数和基肥比例。在此基础上，从16种试验方案中筛选出4种适宜无公害蔬菜的栽培模式，研究结果对控制蔬菜中的硝酸盐积累和预测提供了依据。

| Abstract: | 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 timing were analyzed with data - mining technology of statistical analysis. The experiment results showed that the order of the factor that significantly affect nitrate accumulation was lighting, harvesting timing and fertilization frequency and ratios. In addition, among the 16 experimental designs, 4 cultivation modes were selected for pollution - free vegetable production. The experiment results supplied data basis for nitrate accumulation control for vegetable production. |
