Embodiment

[0021] Example: Demolition of the old area in Yangcenzi Village, Gegu Town, Jinnan District, Tianjin, the reclaimed area is 3.84hm 2 , 105 abandoned village houses with clay soil.

[0022] (1) Clean up the construction waste of the abandoned homestead, and dismantle and transport the surface structures in the area to be reclaimed.

[0023] (2) Carry out land leveling in the reclamation area to minimize the amount of excavation and filling, and the design elevation is 2.66m, so that the ground elevation difference in the entire area does not exceed ±3cm. 3 times. During the ploughing process, the remaining bricks and bricks in the soil should be filtered out, and the large compacted soil should be crushed.

[0024] (3) Divide the reclamation area into 2 typical fields with areas of 100m×200m and 92m×200m respectively. Drainage engineering layout: The hidden pipe adopts two-way drainage, the diameter of the drainage hidden pipe is 70mm, the spacing is 10m, the burial depth is...

Abstract

The invention discloses a reclamation method for rural residence lands on a coastal saline land region. The method includes the first step that building rubbish of the waste residence lands is cleared out; the second step that land leveling is performed on a reclamation area; the third step that water-salt control is performed, according to road planning, the treated reclamation area is divided into land blocks, new irrigation and drainage projects are constructed, and subsurface drainage pipes, water-collecting pipes and water-collecting wells are laid; the fourth step that biological improvement projects are constructed, organic fertilizer and planting green manure are applied to increase the content of organic materials and microorganisms in soil, improve the activity of the soil and complete soil reclamation of the residence lands. According to the method, the residence lands wasted in rural districts are reclaimed into cultivated lands, the utilization rate of the lands is improved, the agricultural acreage is increased, the technologies of land arrangement, water-salt control and biological improvement are organically integrated, and therefore the soil productivity of the residence land can be effectively recovered and farm land ecological environment can be improved. Thus, the reclamation method for the rural residence lands on the coastal saline land region is a practical technology method.

Description

technical field [0001] The invention relates to a method for reclaiming rural homesteads, in particular to a method for reclaiming rural homesteads in coastal salinized areas. Background technique [0002] With the improvement of social and economic development in rural areas and the acceleration of urbanization, more and more farmers have moved into new cities, resulting in a large number of original homesteads being abandoned and idle, resulting in a serious waste of land resources. Against the background of the red line of arable land, the available arable land is decreasing year by year, and promoting the reclamation of rural homesteads has become a top priority. The key to homestead reclamation is to solve the problems of soil compaction, poor air permeability and poor soil activity. [0003] In coastal salinization areas, the groundwater depth is shallow and the groundwater salinity is high, and it is easy to produce salt accumulation on the surface, leading to soil s...
