特效植物营养素对特色蔬菜迟菜心的增产效应

Effect of increasing product by SPNE on late-mature flowering cabbage

迟菜心是广州增城的特色蔬菜,为提高其产量用特效植物营养素(SPNE)喷施迟菜心,两批试验的研究结果均表明,在相同条件下,SPNE喷施后迟菜心的商品产量大幅度高于对照,抗逆性也提高了。其增产效应主要表现为促进叶面积增大、叶绿素增加,使光合作用能力增强,从而植株的叶重增加、绿叶片数增多,苔粗增加,商品产量大幅增加。用SPNE喷施迟菜心,其种子产量、质量都超过对照,使用户在大幅度提高产量和收入的同时获得优良种子。SPNE在农业生产上具有广阔的应用前景。

The late-mature flowering cabbage （Brassica parachinensis Bailey） was specialty vegetable in Zengcheng Guangzhou. The special plant nutritional element （SPNE） was sprayed to the late-mature flowering cabbage in order to increase its yield. Results of two batches showed that the commodity yield and stress resistance of plants treated by SPNE were better than the contrast. The benefit of increasing production was mainly showed up in increment of the leaf area and content of chlorophyl so that the photosynthetic capacity was enhanced, and then increased the weight of plant leaf ,leaf number, diameter of flowering stem and commodity yield. The seed yield and quality at next generation of late-mature flowering cabbage treated by SPNE were better than the contrast. So the users could get good seeds to significantly increase production and income. SPNE would be broad prospects for application in agricultural production.
