Experimental example 1
The experiment is carried out in a test greenhouse, the temperature of the greenhouse is controlled to be 20-25 ℃ during the experiment, the humidity is controlled to be 40-60%, and the experiment period is 30 d. The influence of different treatments on plant greening is evaluated by taking the coverage area of the green bristlegrass herb and the biomass (dry weight) on the ground as indexes. The method comprises the following specific steps:
the greenhouse planting land is divided into 6 groups, and the area of each group is 4m multiplied by 10 m. Adding water into the first components of examples 1-3 and comparative examples 1-3 according to the mass ratio of 1:0.84, uniformly stirring in a stirrer, and then respectively paving in respective test fields to obtain concrete matrix layers with the paving thickness of 6 cm; then, the two groups of the second component are uniformly mixed by adding water according to the proportion of 1:20, and the mixture is paved on a concrete substrate layer with the paving thickness of 2 cm. The water is poured once a day in the first week of the test, and is poured once every 3 days after the week until the test is finished. The vegetation coverage area and the aboveground biomass of each treatment were counted, and the results are shown in table 1.
TABLE 1 area covered by vegetation and aboveground biomass treated differently
| Treatment of | Area of vegetation cover | Aerial biomass (dry weight) |
| Example 1 | 84.5％ | 2.35kg/m 2 |
| Example 2 | 82.6％ | 2.14kg/m 2 |
| Example 3 | 83.8％ | 2.31kg/m 2 |
| Comparative example 1 | 65.5％ | 1.68kg/m 2 |
| Comparative example 2 | 58.2％ | 1.40kg/m 2 |
| Comparative example 3 | 48.5％ | 1.05kg/m 2 |
As can be seen from Table 1, the plant coverage of the groups of examples 1 to 3 was 80% or more, and the average coverage was 83.6%. Compared with the comparative example 1, the plant coverage rate is reduced after the coarse sandstone is replaced by the fine sandstone; plant coverage decreased significantly after further reduction of the length of the bark fibers compared to comparative example 2; compared with the comparative example 3, the plant coverage rate is less than 50% after the rice hulls in the component II are replaced by fallen leaves of plants. Therefore, the material composition and the material structure change of the component I and the component II can influence the growth of plants, and finally, the coverage rate of green plants is influenced.
Statistically, it can be found that the biomass of aerial parts in the groups of examples 1 to 3 is 2.27kg/m on average 2 . While the biomass of the aerial parts of comparative examples 1 to 3 was significantly lower than that of the examplesExamples 1 to 3.
Experimental example 2
The experiment also explores the influence of different using methods of the spray seeding material on plant greening according to the method of the experimental example 1. The components of example 1 were mixed well, then added with water in equal amount and stirred well, and laid on a test field with a thickness of 8 cm. After the experiment is finished, the vegetation coverage area and the biomass (dry weight) of the overground part are counted, and the result shows that the vegetation coverage area is 21.5 percent and the biomass of the overground part is 0.69kg/m 2 . The greening effect was very significantly reduced compared to the treatment of example 1.
The embodiments of the present invention provide a spray seeding material and a method for using the same, which can significantly improve the vegetation coverage and the greening effect of plants by improving the biomass of the aerial parts.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
