The invention discloses a
land consolidation method capable of increasing effective
cultivated land area. The method comprises the steps of firstly, dividing field between two
branch ditches and two lateral draining ditches, dividing field blocks in the field, and leveling land in the field blocks; secondly, respectively building hardened field ditches in boundary positions of all the field blocks, ensuring that the head ends of the field ditches are connected with lateral canals, the
tail ends are connected with the lateral draining ditches, the canal ratio is reduced to 1000:1 to 300:1, and the upper opening of each field
ditch is lower than field surfaces on two sides, and additionally arranging a controlling gate at the junction of each the field
ditch and each lateral draining
ditch; thirdly, arranging a plurality of conical large open wells on identical sides of the field ditches at intervals, and ensuring that the large open wells beside adjacent field ditches are distributed in a staggered way; and fourthly, arranging a diving pump in each large open well, connecting the water outlet with the large open well, and arranging an
automatic control switch on each diving pump. The method can rapidly remove excess
surface water, ensures that the excess
surface water rapidly infiltrates into earth
mass and leaches
saline matter in the earth
mass, reduces the direct runoff rate,
surface layer nutrient loss and water
logging damage, can increase the effective
cultivated land area, and facilitates
irrigation.
