Abstract:
The effect of different concentrations of nutrient solution on the growth of baby Chinese cabbage seedling was studied with ‘Jingchunwa No.2’ as the test material to achieve strong seedlings. The results showed that the seedlings which were grown with nutrient solution at low concentration (0.5 times and 1.0 times) obtained from improved underground water by the vegetables research center of Beijing academy of agricultural and forestry sciences. The seedlings were short and thin, and had low biomass, weak resistance, small root volume and low seedling strength index; and at high concentration (2.5 times), the seedlings were inhibited from growing in early stage. Although they were growing with accelerated speed in later stage, the seedling quality was relatively low. The concentration treatment of 2.0 times significantly promoted the growth of seedlings, effectively increased the biomass, seedling growth index and root activity of seedlings, and well coordinated the growth rate and resistance of seedlings. The salt stress effect was not obvious, and the effect of the concentration on the growth promotion was greater than the effect of stress. Therefore, the optimal concentration of the nutrient solution for the culture of seedlings of baby Chinese cabbage is 2.0 times of the formula of the improved groundwater nutrient solution of the Vegetables Research Center of Beijing Academy of Agricultural and Forestry Sciences.
