| Abstract:
The dynamics of the growth of seakale plants, the concentrations of various nutritional elements in the plants and the uptake of the elements by plants during different growing periods was studied in Angers, France. The results show that the total growth of seakale plants in the field five months after transplanting was 10.47 t/ha (dry matter). The order of seakale whole plant growth during various periods was greatest in the 5th month > the 3rd month > the 2nd > the 4th month > the 1st month. The concentrations of B, S, Ca, and P are the highest in the 2nd month, and lowest in the 5th month; the concentrations of Cu, Fe, and Mn are highest in the 1st month, and after sharply declining, do not change much in the other periods. The concentrations of Zn and Mg decrease with the continued growth of seakale plants, and the concentrations of K and Na are relatively stable in the various growing periods. In terms of the total uptake of various nutritional elements during the entire growing season the results were: K> Ca> S> P> Mg> Na> Fe> Mn> Zn> B> Cu, and the order of magnitude of elemental uptake except for Mn in various growing periods is the 5th month> the 3rd month> the 2nd month> 4th month> the 1st month. | |
