| 摘 要： | 本文就土施Ｌ－色氨酸即Ｌ－ＴＲＰ对盆栽甘蓝产量和养分吸收的影响进行了研究。结果表明，在移植前一周土施Ｌ－ＴＲＰ，能明显提高甘蓝产量和干物质积累，并明显促进了甘蓝植株对Ｎ、Ｐ、Ｋ的吸收，提高了Ｎ、Ｐ在球叶中的分配，降低了Ｋ在球叶中的积累。

| Abstract: | A study was conducted to determine the influence of L-TRP(L-tryptophan) applied to soil on the yield and nurtient uptake of cabbage (Brassica olercea Var. capitata L.)in a pot experiment. The results showed that L-TRP applied to soil a week before transplanting might obviously increase the cabbage yield, dry matter accumulation and the uptake of nitrogen, phosphorus and potassium of cabbage plants, Nitrogen and phosphorus distributed in the head leaves increased but potassium decreased. |
