Embodiment 1

[0043] Embodiment 1: the first step needs to be slotted and transported to another place, wherein it needs to spend about 10 yuan / square meter for slotting machinery costs and transportation costs; the second step is to complete the slotting and need to lay a 20 cm thick shower layer 2, per square meter 10 yuan per meter; the third step blind ditch needs to increase the cost of blind pipe 3, 4.5 yuan per meter; the fourth step to complete the above three tasks, need to backfill planting soil 1, at least 22 yuan per square meter.

[0044] In comparison, the cost savings of the new plan are as follows: 1. No slotting and soil removal, but deep plowing on the spot, which only costs 2 yuan / square meter, so that only the cost of slotting can save 8 yuan / square meter; 2. No laying The drench layer, because we use the capillary infiltration of the soil to achieve the effect of sprinkling salt and alkali, so we don't need to lay a drench layer, which can save 8 yuan per square meter in...

Embodiment 2

[0045] Embodiment 2: the new scheme step disclosed by the present invention is:

[0046] 1. Dig water ditch 5 on the land to be transformed, branch ditch 5b and main ditch 5a, branch ditch 5b parallel to each other, dig one every 10 meters, main ditch 5a and each The branch ditch 5b intersects vertically; both need to be dug 1.3 meters deep from the ground level; the width of the ditch 5 is 30 centimeters.

[0047] 2. Lay a woven fabric belt 8 in the excavated ditch 5, and backfill 30 cm of slag 7;

[0048] 3. Cover tightly with the slag 7 backfilled with the woven cloth belt 8, that is, build the blind water ditch 6, and at the same time prevent the soil foam from leaking into the ditch when watering and affect the smoothness of the drench;

[0049] 4. Backfill the soil 15 excavated from the ditch; that is, backfill the ditch 19 in the attached drawing;

[0050] 5. Add fermented cow and horse manure fertilizer 100mm to the soil surface after backfilling;

[0051] 6. Then d...

Embodiment 3

[0055] Embodiment 3, the present embodiment is the description of the supplement of embodiment 2, that is, the automatic precipitation system:

[0056] In the area that should be greened and planted, if the water level is too high, it will directly soak the root system of the plant, which will directly cause the plant to drown, especially the water with high salinity, which is more harmful to the growth of the plant. Soaked in salt water, the root system rots and dies quickly, so to transform the saline-alkali land, the first thing to do is to control the reasonable water level of the plant section. We use a series of measures to lower the plant plots to a fixed position line. After careful research and thinking, we think that we can use deep and strong drainage wells to solve this problem. The capillary infiltration leads to the strong drainage well, thereby reducing the water level of the plant section. If the reclaimed water equipment is used, the waste water can also be st...

Abstract

The invention discloses a water-saving salt marsh physic-chemical-ecological integrated modification and vegetation construction technique. The invention firstly digs a dripping slot at the ground needed reconstructed, and lays the material which is anti-corrosion and permeable in said dripping slot and lays a certain depth of stones above this; covers the stones with the material which is anti-corrosion and permeable to construct the dripping blind slot; backfills the soil excavated from said dripping slot; fills the acid organic manure above said backfilled soil surface; processes deep tillage on the manure soil to laid acid organic manure; and constructs the salt-extract permeable channel. The invention also has an automatically precipitation system. The invention has the advantages that: it avoids dig slot, remove soil, lays dripping layer, lays blind pipe, changes planting soil, which can confirm the normal growth of nursery-grown plant and avoid the destroy on the infield.

Description

(1) Technical field: [0001] The invention belongs to a method for comprehensive improvement of saline-alkali flats, in particular to a technology for comprehensive physical-chemical-ecological improvement and vegetation construction of water-saving saline-alkali flats. (two) background technology: [0002] Seaside saline-alkali land has a low groundwater level, few types of natural vegetation, and xerophytic vegetation is even difficult to grow, making it difficult to use land. However, with the development of society and economy, the expansion of population, the acceleration of urbanization and the rapid expansion of cities, land has become more and more a valuable resource. In the coastal cities with rapid economic development, tidal flat saline-alkali land has become or is becoming the object of development, and has even become the cradle of high-tech incubation and the basis for revitalizing the local economy. However, in the process of developing tidal flats, the elega...
