A study of the effect of a tidal non-soil cultivation facility on the cultivation of cabbages
Abstract: Paper is contrast with Lu SC soilless cultivation system, planting four times in the two kinds of cultivation groove body short feet yellow Chinese cabbage, through the determination of the growth of Chinese cabbage in different cultivation groove results index and physiological index and the results show that the new cultivation groove can supply within 15 minutes to 80% water content, fully meet the needs of plant roots to moisture and oxygen, can promote plants growth.New cultivation groove on the substrate consumption, water consumption and material consumption, respectively, compared with the control saves 4.33%, 28.53% and 10.86%, significantly lower production costs and increase production by 38.4%.on facility
