Abstract
In order to guide the rational fertilization and to produce Eruca sativa Mill with high yield and quality , taking Eruca sativa Mill as experimental material ,substrate culture was adopted to study the effects of differ-ent combined application of nitrogen and potassium levels on the yield formation ,chlorophyll content ,root ac-tivity ,fresh weight of aerial and underground part ,fresh and dry weight of single plant were measured .The re-sults showed that the yield of single plant was higher ,chlorophyll content was higher ,root activity was stron-ger ,fresh weight was more when the combined application of higher N and higher K which were N 3 K3 ,N3 K4 , N4 K3 and N4 K4 (N3 :7 .5 mmol·L-1 ,N4 :10 mmol·L-1 ,K3 :4 .5 mmol·L-1 ,K4 :6 mmol·L-1 ) ,that were deter-mined to be the most suitable combined application ratios .关键词
