摘　　要：用特效植物营养素(SPNE)对不同时期种植的迟菜心采取相同的方法喷施植株,比较SPNE对迟菜心生物产量、商品产量、种子产量的影响差异。结果表明:SPNE处理方法相同但迟菜心种植时期不同,SPNE对迟菜心的生物产量、商品产量、种子产量的增产效果都很明显,但种植时期不同处理效果存在差异,在适宜迟菜心生长的时期使用SPNE增产效果更佳。Special Plant Nutritional Element （short for ＂SPNE＂） was sprayed to plant of late flowering cabbage that were planted in different time, and the biological yield, commodity yield, seed yield were compared. The results showed that for the plant treated by SPNE in the same way but were planted in different time, the effect of increase yield that above character is very obvious to all when treated by SPNE in same way but difference to planted in different time. The treated effect was the best by SPNE when planted in good time for late flowering cabbage.
