Embodiment 1

[0030] Embodiment 1 Saline-alkali land improver formula

[0031] Said saline-alkali land improving agent includes powder and water,

[0032] The powder comprises the following components by weight: 10 parts of organic bentonite, 5 parts of modified rectorite, 15 parts of organic fertilizer, 12 parts of humus, 25 parts of compound fertilizer, 7 parts of amino acid, 0.8 part of polyacrylamide, biological flora 0.3 copies;

[0033] The rectorite is ground into a fine powder with a ball mill and calcined, then organically modified with cetyltrimethylammonium bromide as an intercalation agent, and finally the modified organic rectorite is melted with polypropylene Mixed on a twin-screw screw machine to prepare modified rectorite.

[0034] The organic fertilizer is animal manure and plant straw; the compound fertilizer is a mixture of potassium fertilizer, phosphorus fertilizer and nitrogen fertilizer in parts by weight of 3:6:12, and the biological flora includes Bacillus subtili...

Embodiment 2

[0037] Choose a piece of Weifang coastal saline-alkali land, choose tall thatch for planting, plant in different regions, and set up control samples and comparison samples (the control sample is planted with high water pressure salt and ordinary irrigation, and the comparison sample is planted with this method combined with saline-alkali soil improvers).

[0038] Terrain finishing: the saline-alkali land to be improved will be sorted out, and the flat land will be leveled with high digging and low filling, with a maximum slope of 5 。 ;

[0039] Laying of hidden salt drainage pipes: laying hidden salt drainage pipes with a trenching pipe burying machine, the buried depth of the buried salt drainage pipes is 0.7m, and the slope is 0.3‰. The distance between two adjacent hidden salt drainage pipes is 30m, and there are water collecting pipes connected to each of the hidden salt drainage pipes respectively. Wrap the 8cm sand filter material, choose the natural sand with uniform d...

Embodiment 3

[0048] Select a piece of Weifang coastal saline-alkali land, choose Poa annua planting, and plant in different regions, and set up control samples and comparison samples (the control sample is planted with high water pressure salt and ordinary irrigation, and the control sample is planted with this method combined with saline-alkali soil improvers).

[0049] Terrain arrangement, hidden pipe laying and desalinated water equipment installation are the same as in Example 2.

[0050] Lawn planting: a) Soil improvement, sprinkle the powder of saline-alkali land improver on the soil surface with a thickness of 0.8cm, then plow 30cm deep, and finally dilute the water agent of saline-alkali land improver by 500 times and spray on the soil surface, repeat spraying once every 5 days, and spray twice in total , according to the diluted 30g / ㎡spray.

[0051] b) turf transplantation, excavate a radius of 15cm on the land to be planted, a circular planting hole with a depth of 15cm, the adja...

Abstract

The invention discloses a method for planting lawn on saline-alkali land. The method comprises the following steps of firstly leveling the terrain of the selected saline-alkali land; then laying salt draining hidden pipes; mounting a brackish water desalination system, and desalting raw water of the saline-alkali land and collected saline water into fresh water provided for irrigation, so that brackish water of the saline-alkali land is reasonably utilized, and fresh water transporting cost can also be reduced; planting lawn, selecting salt-resistant varieties, improving soil with water agents and powder agents of saline-alkali land improving agents, and providing organic matters and trace elements, which are required for the growth of plants; and besides, continuously supplying water in a real-time and automatic manner at appropriate time and in an appropriate amount by using a drop irrigation-micro jet irrigation technique. According to the method for planting the lawn, fewer water resources are consumed, the survival rate is high, and growth conditions are good.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land improvement, in particular to a lawn planting method on saline-alkali land. Background technique [0002] Saline-alkali land is a kind of soil type widely distributed in the world, and it is an important land resource. The saline-alkali land area in the world is about 15 billion mu, and the saline-alkali land area in my country is about 540 million mu, accounting for one-thirtieth of the world; the saline-alkali land in my country is about 90 million mu, and the cultivated land in my country is only 1.5 billion mu, accounting for nearly one-tenth of the cultivated land area in my country. one fifth. At present, it has become the biggest obstacle restricting the construction of ecological environment and the sustainable development of agriculture in our country. At the same time, with the reclamation of large areas of land, soil salinization caused by unreasonable irrigation and water q...
