Abstract:
he irrigation arrangements are conceived, designed, realized and
exploited as ecological engineering works, flexibly dimensioned depending
on the change in time of some climatic elements found by studies.
The issue of environmental protection depends on the quality of the
components and it is conditioned by the efficient use of the offalls resulted
from the worn out components.
The researches were performed in a representative region of
Romania, involving digging and irrigation works on drained land. The
experimental field has a surface of 4 ha and it is located in the meadow
research worksite of INCDIF, Baneasa, Giurgiu county.
The annual concentration of C absorbed by plants is of 30-60 billions
tones (table 1). The interval of variation of daytime intensity of
photosynthesis depending on the cultivated plant is presented in table 2.
The dimensioning of the regularization network with double is made
using the concept of maximum capitalization of the phreatic water inside the
plot, being defined the intervals of variation of the phreatic level for realizing
drainage/discharge-irrigation and storage of water in the plot.
The method of capitalizing land is represented by the selection of the
plant depending on the best location of the phreatic level and the amount of
CO2 absorbed.
