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。 In a suburb of Shenzhen vegetable base for cabbage, cabbage nitrate accumulation test, the use of statistical analysis of data mining techniques field cultivation, lighting, fertilization techniques, harvest time and other factors were studied and analyzed in 16 treatment options , Four kinds of cultivation modes suitable for pollution-free vegetables were screened out. The factors that significantly affect the accumulation of nitrate in vegetables were found to be sunshine, harvest time, topdressing times and basal fertilizer ratio. The results provide the basis for inhibiting nitrate accumulation in vegetables The basis.
