盆栽试验表明，土壤施硒或叶面喷硒均可显著提高小白菜（ＢｒａｓｉｃａｃｈｉｎｅｓｉｓＳｓｔ．）体内的含硒量。在施硒量为１．５、３．０μｇ／ｇ时，有机硒占全硒的６６％和７１％，比对照提高了３８％和４３％，土壤施硒使小白菜体内有机硒含量增加。硒肥喷施与土施相比，是提高小白菜含硒量的有效方式。施硒处理能提高必需氨基酸含量及氨基酸总量，其中苯丙氨酸和精氨酸较对照分别增加１倍和２．５倍以上。
Pot experiments showed that selenium content in Chinese cabbage (BrasicachinesisSst.) Was significantly increased by either selenium application or selenium spraying on leaves. Organic selenium accounted for 66% and 71% of total selenium at selenium application rates of 1.5 and 3.0 μg / g, respectively, which were 38% and 43% higher than that of the control. Soil selenium increased the content of organic selenium in Chinese cabbage. Selenium fertilizer application compared with soil, is an effective way to improve the selenium content of Chinese cabbage. Selenium treatment can increase the content of essential amino acids and total amino acids, of which phenylalanine and arginine were increased by 1 times and 2.5 times more than the control.
