How to plant and maintain lawns in saline land

For lawn planting on saline-alkali land, the first choice is to improve the soil, you can apply ferrous sulfate 200kg per mu, and then water it again to neutralize the acid and alkali in the soil, and the soil can be planted with lawn after trimming.

If it's a green city, the simplest thing is not to improve it in the saline-alkali land, directly spread 10 cm of floating soil, and then plant, water and fertilizer, that is, it has nothing to do with the saline-alkali land. Or after improving the saline-alkali land

The movement law of water and salt is to return salt in spring, pour salt in summer and autumn, and salt is relatively stable in winter. The growth of crops requires the proper regulation of the movement of salt in the soil. Cover with mulch and lightly drizzle salt.

When planting a lawn in saline soil, it is important to choose seeds that are suitable for growing in saline soilBecause if the seeds are not suitable for growing in saline-alkali land, it is easy to affect the effect of normal growth, and it will also cause the grass leaves to appear yellow and even die; In addition, saline-alkali land is generally very water-scarce, and the lawn species selected should also be drought tolerant. In addition, if the lawn planting area is not particularly large, you can use the method of soil exchange, and replace the soil about 30 cm on the surface with normal soil before planting. If it is a large-scale planting, you can first plant some alkali thatch, alkali grass and other grass species with particularly strong resistance to salinity and alkali, improve the soil environment, and then plant some green manure plants such as milk vetch and alfalfa after three or five years of planting, and gradually improve and optimize the soil environment.

Saline-alkali land is particularly picky about the varieties of forage, and the general forage is not easy to survive in saline-alkali land, so the selection of varieties is suitable to see whether the characteristics of forage are suitable. And be careful, otherwise it is easy to get nothing.

Heavy alkaline land should be selected with strong alkali tolerance of alkali grass, satawang, purple locust, field cyanine, artemisia, caragana, long-spike ice grass, weeping spike alkali grass, sheath paspalum, light stamen, new wheat grass, rice grass, etc.;

Moderately alkaline land can be planted with moderately alkali-tolerant herbs, alfalfa, hairy roots, and alkali grass.

Rice grass is particularly salt-tolerant and is suitable for growing in the mid-tidal zone where the normal salinity of seawater is high soil salinity. In saline-alkali land, the stems and leaves can still be kept green. It is also resistant to flooding, and can grow normally every time the tide is submerged for a long time.

It can withstand a certain amount of wind and waves. Silt resistant, the plant can generally grow with siltation, but it is not tolerant to all special silting. It is resistant to high temperatures, and can still grow in tillers if there is enough moisture.

The root system of rice grass criss-crossed, particularly developed, the ability to absorb phosphorus is strong, the root system is not easy to rot under the condition of gas abusiveness, the bacteria in the root zone increase, and the regeneration is faster after mowing, and the grass yield can be increased by mowing 1-3 times a year. It can be born in seawater and saline soil, and also adapt to grow in fresh water, light soil, soft and hard mudflats and sandy beaches. The tillering power is particularly strong, and it can be turned into a pasture in a few years.

Giant Juncao, Oasis No. 1, etc., can improve saline-alkali land.

Saline-alkali land is a general term for saline soil and alkaline soil. Saline soil mainly refers to salinized soil with high chloride or sulfate content, and the soil is alkaline, but the pH value is not necessarily high. Alkaline soil refers to soil containing carbonate or biphosphate, with a high pH value and alkaline soil.

Saline-alkali soil has less organic matter content, low soil fertility, poor physical and chemical properties, more anions and cations harmful to crops, and crops are not easy to promote seedlings. Due to the high salinity, alkalinity, the soil structure is damaged, manifested as wet when sticky, dry when hard, the soil surface often has white salt deposit, aeration, poor water permeability, serious will cause plant wilting, poisoning and rotten root death, so it is best to improve the soil on the saline-alkali land before planting.

Commonly used can improve soil composition and structure, enhance soil permeability, and accelerate salt leaching by deep tillage, land leveling, grass covering, siltation, sand covering, and organic fertilizer application.

Planting and turning green manure forage, straw returning to the field, applying biological agents, planting salt-tolerant plants (Giant Juncao, Oasis No. 1), afforestation, etc., to improve soil fertility, improve soil structure, and improve farmland microclimate, reduce surface water evaporation, and inhibit salt return.

The most suitable lawns for planting in moderately saline land are tall fescue lawns, rye grass lawns, and white clover can also be planted.

Zhang Xinshe, Jiaxin Lawn Plantation in Luancheng County, Shijiazhuang City, Hebei Province, has been planting high fescue tolerant to salt and alkali for many years. He has been planting lawns for more than ten years, and according to him, after laying the grass in Tianjin, it can survive at that time, but it will slowly turn yellow and die in Futian. But the tall fescue lawn is different, it can withstand the humidity of Tianjin Futian and the return of salinity to the land.

If it's some kind of lawn.

If it is a green city, the simplest is not to improve the saline-alkali land, directly pave 10 cm of floating soil, and then plant, water and fertilizer, that is to say, it has nothing to do with the saline-alkali land. Or after improving the saline-alkali land

When planting a lawn in saline soil, it is important to choose seeds that are suitable for growing in saline soilBecause if the seeds are not suitable for growing in saline-alkali land, it is easy to affect the effect of normal growth, and it will also cause the grass leaves to appear yellow and even die;

In addition, saline-alkali land is generally very water-scarce, and the lawn species selected should also be drought tolerant.

If the lawn planting area is not particularly large, you can use the method of soil changeReplace the soil of about 30 cm on the surface with normal soil before planting.

If it is planted in a large area, you can first plant some alkali thatch, alkali grass and other grass species with particularly strong salt and alkali resistanceImprovement of the soil environmentAfter three or five years of planting, some green manure plants such as milk vetch and alfalfa were planted to gradually improve and optimize the soil environment.

Turf planting in sandy saline land is indeed more difficult, but there are several steps that can be taken to deal with it:

1.Soil improvement: The soil of saline-alkali land generally contains high salinity and needs to be improved. Lime, organic fertilizers, etc. can be applied before planting to reduce the salt content and improve soil quality.

2.Choose the right grass species: When planting a lawn in sandy saline soil, you need to choose a grass species that is suitable for the environment. For example, you can choose salt-tolerant grasses, such as wolftail grass, alkali grass, etc.

3.Planting techniques: When planting a lawn, you need to pay attention to the following:

Before sowing, sufficient tillage should be carried out to loosen the soil;

When sowing, pay attention to the density and depth of grass seeds to ensure the neatness and beauty of the lawn;

After sowing, it is necessary to water in time to keep the soil moist and promote the germination and growth of grass seeds;

Proper fertilization should be carried out after planting to increase the nutrient content of the lawn.

4.Regular maintenance: After the lawn is planted, regular maintenance is required, including watering, fertilizing, mowing, etc. At the same time, it is necessary to pay attention to the prevention and control of lawn diseases and pests to maintain the healthy growth of the lawn.

In general, turf planting in sandy saline land requires adequate soil improvement and grass seed selection, as well as attention to planting techniques and regular maintenance.
