- Abstract:
- Chinese cabbage (Brassica chinensis),lettuce (Lactuca sativa),amaranth (Amarantus mangostanus) and spinach (Spinacia oleracea) were cultivated in the pot in the biotron,using soilless culture mediums composed of decomposed coal gangue and rape straw.Five culture mediums were set,with the volume ratios of decomposed coal gangue and rape straw of 2∶8,3∶7,4∶6,5∶5 and 6∶4,respectively,with garden soil was used as control.After 30 days and 55 days cultivation,the content of nitrate,the vitamin C,the soluble sugar,and the organic acid in the four leafy vegetables were measured.At the same time,the physiological characteristics of soilless culture mediums,as well as the quality characteristics of the four vegetable crops growing on different mediums were studied,in order to determine the best soilless culture medium.The results showed that the five soilless culture mediums had good physiological properties,with lower unit weight,better water-air ratio,and more nutrition.Compared to the control,the vegetable crops growing on the soilless culture mediums had significantly lower nitrate and organic acid content,and remarkably higher content of vitamin C and soluble sugar,especially in the soilless culture medium of 4∶6 and this medium as the best.
