TABLE 3 EC values of soils before and after lawn laying by the methods of examples 1 to 4 and comparative examples 1 to 9

As can be seen from the data in Table 3, after the lawn is paved by the method in the embodiments 1-4 of the invention, the EC value of the soil can reach about 2.0mS/cm in 30 days after the lawn is paved, which shows that the content of soluble salt in the soil can be effectively reduced by paving the saline-alkali soil by the method of the invention.

No. 5 land cause comparative example 1 does not use soil conditioner in the paving method, the EC value after treatment is reduced more slowly, and the EC value is still more than 2.21mS/cm at the 30 th day of treatment, which shows that the soil conditioner prepared by the invention can effectively reduce the content of soluble salt in soil.

The fact that the soil conditioner of No. 6 is used in the process of spreading, the content of ES value in the soil is gradually reduced after spreading, but the EC value is slowly reduced at 25 th and 30 th days, and the EC value is still more than 2.42mS/cm at 30 days indicates that the soil conditioner of the market has the effect of reducing the content of soluble salt in the soil, but the treatment effect is not as long as the effective period in the embodiments 1-4 of the invention.

No. 7 soil conditioner does not refer to traditional Chinese medicine dregs, animal wastes and furfural dregs, after the soil is paved with the lawn, the EC value is gradually reduced, but is still more than 2.18mS/cm in 30 days, which indicates that the traditional Chinese medicine dregs, the animal wastes and the furfural dregs are used cooperatively, so that the EC value reduction effect in the soil is more obvious.

No. 8 ground does not add high molecular polymer, vermiculite powder and desulfurization gypsum in the soil improvement agent, and soil EC value reduces comparatively slowly when 5 th day and 15 th day, and still is more than 2mS/cm when 30 days, shows that adding high molecular polymer, vermiculite powder and desulfurization gypsum can the synergistic effect, promotes the reducing rate of EC value, accelerates the treatment effect in saline and alkaline land.

No. 9 land is not covered with nutrient soil, No. 10 land is replaced with commercial nutrient soil, and the EC value of No. 10 land is less than that of No. 9 land but more than that of No. 1-4 land in 30 days, which shows that the effect of the nutrient soil in reducing the EC value is good, and the content of the EC value in the soil can be reduced by the nutrient soil.

No. 11 caffeine nutrient soil is not added with a rooting inducer, diatomite and decomposed coffee grounds, and the EC value of the nutrient soil at 30 days is greater than that of the nutrient soil at 30 days of No. 9 land, so that the rest components in the nutrient soil can play a role in reducing soluble salts, but the EC value of the nutrient soil at 30 days is still greater than that of the nutrient soil at No. 1-4 land, so that the content of the soluble salts in the soil can be synergistically reduced by using the turfy soil, the diatomite and the decomposed coffee grounds.

No. 12 land is not added with biological nutrient solution, and the EC value in soil is still more than 2.21mS/cm at 30 days, which shows that the content of soluble salt in soil can be obviously reduced by adding the biological nutrient solution.

The content of EC value of No. 13 land is gradually reduced because wormcast, radix puerariae powder and calcium ammonium nitrate are not added into the biological nutrient solution, but the EC value of the land on the 25 th day and the 30 th day is not greatly changed, and is still more than 2.4mS/cm on the 30 th day, and the content of EC value of the soil is less than that of No. 12 land but still higher than that of No. 1-4 land on the 30 th day, which indicates that the content of soluble salt in the soil can be obviously reduced by adding wormcast, radix puerariae powder and calcium ammonium nitrate.

TABLE 4 pH of soil before and after laying lawn by the methods of examples 1-4 and comparative examples 1-9

As can be seen from the data in Table 4, the method of the invention in the saline-alkali land for the No. 1-4 land can obviously reduce the pH value of the saline-alkali land by adopting the method of the invention in the embodiment 1-4 land, and the pH value of the soil can be reduced to below 7.6 after 30 days of the planting, which indicates that the method for planting the lawn can effectively reduce the alkali content in the soil, so that the original moderate or high saline-alkali land becomes the weak alkaline soil with the pH value of 7-8, and the method is more suitable for the growth of the lawn.

No. 5. the method for laying the lawn in the comparative example 1 does not use the soil conditioner, the pH value is reduced on the 5 th day and the 15 th day, but the change of the pH value is not obvious on the 25 th day and the 30 th day, which shows that the soil conditioner can effectively reduce the alkali content in the soil, so that the saline-alkali soil is suitable for the growth of the lawn.

The No. 6 land uses the existing soil conditioner on the market when in paving, the alkali content of the soil is reduced after the lawn is planted, but the pH value is still larger than 8 at the 30 th day, the alkalinity is strong, and the soil is not suitable for the growth of the lawn.

No. 7 is a soil conditioner without traditional Chinese medicine dregs, animal wastes and furfural dregs, No. 8 is a soil conditioner without high molecular polymer, vermiculite powder and desulfurized gypsum, the alkali content in soil is reduced on days 5 and 15, and on day 30, the pH value is still above 8.0, and the alkali content is high, so that the soil conditioner is not suitable for lawn growth.

No. 9 land has no nutrient soil laid on the soil, No. 10 land has no pH value of above 8.0 because the nutrient soil prepared by the invention is replaced by commercial nutrient soil, and the pH value of the soil in No. 9 land is higher than that of the soil in No. 1-4 although the pH value of the soil in No. 10 land is below 8, which indicates that the growth speed of the lawn in No. 10 land is lower than that of the lawn in No. 1-4 land.

No. 11 caffeine nutrient soil is not added with a rooting inducer, diatomite and decomposed coffee grounds, and through improvement, the pH value of the soil is still higher, and the growth speed of the lawn is slower.

No. 12 land is not added with biological nutrient solution, No. 13 land is not added with wormcast, kudzu root powder and calcium ammonium nitrate, and the pH values of the No. 12 land and the No. 13 land are both high, so that the lawn is not suitable for growth.
