Embodiment 1

[0019] According to the development and arrangement of the project area, when the project area is located between two bucket-level drainage ditches 1, take the distance between the two branch ditches as the length, and the distance between the two bucket-level drainage ditches 1 (500-600 meters) as the Divide the field by width, divide the field every 150 meters in the field, level the land in the field, build a hardened agricultural canal 2 at the boundary of each field, the head of the agricultural canal 2 is connected with the bucket-level canal 3, and the tail is connected with the bucket-level row Ditch 1 is connected, the channel ratio is 500:1, and the upper mouth of the agricultural channel 2 is slightly lower than the fields on both sides, such as figure 1 As shown, to ensure that the accumulated water in the rainy season can flow into the canal, the connection between the agricultural canal 2 and the bucket-level drainage ditch 1 is provided with a control gate 4 to f...

Embodiment 2

[0021] According to the area of ​​the project area according to the development and arrangement, when the project area is located between two branch-level drainage ditches, the distance between the two branch-level drainage ditches is taken as the length, and the distance between the two bucket-level drainage ditches 1 (500-600 meters) is taken as the width Divide the field, divide the field every 170 meters, level the land in the field, build a hardened agricultural canal 2 at the boundary of each field, the head of the agricultural canal 2 is connected to the bucket-level channel 3, and the tail is connected to the bucket-level drainage ditch 1 connection, the channel ratio is 500:1, and the upper mouth of the agricultural channel 2 channel is slightly lower than the fields on both sides, such as figure 1 As shown, through this structure, it is ensured that the accumulated water in the rainy season can flow into the canal, and a control gate 4 is added at the junction of the ...

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of land consolidation, in particular to a land consolidation method capable of increasing the effective cultivated land area. Background technique [0002] The Huang-Huai-Hai Plain refers to the largest plain in my country formed by the contiguous deposition of the lower reaches of the Yellow River, Huai River, and Hai River. It is located south of the Great Wall, north of the Huai River, east of the Taihang Mountains and the mountains in western Henan, including Shandong Province, Beijing, and Tianjin All, most of Hebei and Henan provinces and the Huaibei Plain in Anhui and Jiangsu provinces, involving a total of 379 counties (cities, districts). The Huang-Huai-Hai Plain is located between 32°-40°30' north latitude and 113°-120°30' east longitude, with a total land area of ​​about 450,000 square kilometers, including 24.06 million hectares of cultivated land, accounting for about 18% of the country's cultiva...
