摘 要：
采用田间施药方法,研究了不同浓度植保康对大棚中普通白菜生长、硝酸盐含量、营养品质及土壤性质的影响。结果表明,施用植保康后,普通白菜叶片数、最大叶面积和产量均有所提高,其中以植保康施用量22.5kg·hm-2的效果最为明显。在营养品质方面,不同浓度植保康的施用效果不同,22.5kg·hm-2处理的植株硝酸盐含量最低,而15.0kg·hm-2处理的植株VC含量较高。添加植保康有效降低了土壤全盐量,提高了土壤微生物数量。综合各项因素,生产中植保康施用量以22.5kg·hm-2为最佳。

摘 要：
This research focuses on the effects of different levels of microorganism agent-Zhibaokang on the growth,nitrate content,nutritional quality of Brassica campestris L.ssp.chinensis(L.)Makino var.communis Tsen et Lee and soil condition.Results showed that microorganism agent had significant effect on the leaves number,maximum leaves area and yield of Brassica campestris L.ssp.chinensis(L.)Makino var.communis Tsen et Lee,especially at a concentration of 22.5 kg·hm-2 level,and the plant had the lowest nitrate content at 22.5 kg·hm-2 level.But for the content of VC,15.0 kg·hm-2 level was the highest.Furthermore,the soil salt content was reduced and the microbial number increased significantly with the addition of microorganism agent-Zhibaokang.In conclusion,microbial agents at concentration of 22.5 kg·hm-2 level has the optimal economic effect.
