以黑叶白菜为试验材料,设计3种日本园试营养液配方浓度,研究其对黑叶白菜无土栽培生长及产量的影响。研究结果表明,在园试标准营养液配方l/8～l/2浓度范围内,随着营养液浓度的提高,黑叶白菜各植株鲜质量、小区产量及植株的叶长、株高、叶数、植株干质量、根干质量均有不同程度的增加,其中园试标准营养液配方1/2浓度处理最高。
Taking black cabbage as test material, three kinds of Japanese garden nutrient solution concentration were designed to study the effect on non-soil culture growth and yield of black cabbage. The results showed that in the range of l / 8 ~ l / 2 of the standard nutrient solution, the fresh mass, cell yield, leaf length, plant height, leaf height The dry matter weight and root dry weight of the plants increased in varying degrees. Among them, the highest concentration of 1/2 nutrient solution in the garden test was obtained.
