Problems solved by technology

These studies show that: from the perspective of growth nutrition, domestic waste compost can meet the requirements of lawn plant growth, but the biggest problem is: waste compost is loose in texture, which makes it difficult for the substrate to combine with the ryegrass root system, and such As a result, this technology cannot be applied in practice, that is to say, this technical bottleneck cannot be broken through, which means that this good idea will be shelved forever
These research results show that: ① When using bean straw and municipal solid waste compost to combine turf matrix, ryegrass has a better performance in the early growth stage {Lian Fei, Zhao Shulan, Duolian, Municipal solid waste compost (sieved with 200 mesh sieve) and bean straw are used as turf substrate and the ecological response of ryegrass, Journal of Agricultural and Environmental Sciences, 2007, 26)}, but in the later stage of ryegrass growth, when ryegrass needs to establish a huge root system, the root growth is inhibited, this Similar phenomena have also appeared in other studies, such as the inhibitory effect of rice straw residues on certain types of rice straw, the mechanism of which is complex, which may be related to other effects. In addition, domestic waste composted through a 200-mesh The substrate is still very easy to fall off from the root system of lawn plants; and this research result finally indicates that the technical route of using crop straw and municipal solid waste compost (screened with a 200-mesh sieve) to assemble the lawn substrate will be possible. Difficult to pass
② When using sawdust mixed with basswood and birch and municipal solid waste compost (screened with a 200-mesh sieve) to form a turf matrix (Duo Li'an, Zhao Shulan, research on matrix selection for environmental ecological engineering of carpet-type turf produced by domestic waste. Application Acta Ecologica Sinica, 2000, 11); also appeared similar to the results of "using bean stalks and municipal solid waste compost to assemble lawn substrates", the mechanism is unknown, and this research result also shows that the use of mixed It may be difficult to combine sawdust and wood chips with municipal solid waste compost (screened with a 200-mesh sieve) as a lawn substrate
[0006] In short, the above series of research results give us a conclusion: if we can’t find a solution to the problem of loose texture of garbage compost, we can’t solve the problem that the substrate is difficult to combine with the roots of ryegrass; The performance of the matching materials and the matrix cannot be improved
The application technology of garbage composting in the lawn mechanism cannot be applied in practice
In a word, due to the above-mentioned combination of soybean straw and municipal solid waste composting turf substrate, the application effect is not good, it seems that the way of using straw to combine garbage composting turf substrate is not feasible

Embodiment 1

[0061] The rice stalks are pulverized and dried, mixed according to the ratio of rice to compost of 1%, 2%, and 3%, and 100g of each is prepared.

[0062] First, crush the larger soil clods in the garbage and dry them for more than 8 hours to a constant weight, then sieve them through a 200-mesh sieve, then use a 200-mesh sieve to filter them, and use a hammer to crush the large pieces of sifted garbage and re-sieve them. Make effective use of the components in the garbage. The compost used in the experiment first removed all kinds of wood, plastic, glass, metal and other sundries, and then dried it to constant weight at 105°C, and sieved the compost with a particle size of 1700nm. 1700nm particle size compost is pulverized under 24000 rpm, and the time is 3min respectively, to prepare the 300nm garbage micro-fertilizer of particle size, and use S4800 field emission scanning electron microscope (S4800, JAPAN) fine municipal solid waste compost particle size analysis (following...

Embodiment 2

[0065] Mixing and composition: mixing the pulverized rice stalks and compost soil at a ratio of 2% of the rice stalks. Sprinkle 100 seeds evenly in the matching medium, place them on a biological culture platform for cultivation, ventilate naturally, and water them uniformly and quantitatively until the end of the experiment. The temperature and humidity were measured every day, and the temperature was 23°C and the relative humidity was 56%. Cut after about 28 days, and measure the germination rate of the seeds. Seed germination rate and germination potential are most similar to those of soil.

Embodiment 3

[0067] Mixing composition: the crushed rice straw and the compost soil are mixed at a ratio of 3% of the crushed rice straw. Sprinkle 100 seeds evenly in the matching medium, place them on a biological culture platform for cultivation, ventilate naturally, and water them uniformly and quantitatively until the end of the experiment. The temperature and humidity were measured every day, and the temperature was 23°C and the relative humidity was 56%. Cut after about 28 days, and determine the germination rate and germination potential of the seeds to be most similar to those of the soil.

Abstract

The invention relates to application of a mixed turf matrix in promoting germination percentage of ryegrass. The germination percentage, the growth height, the single plant net photosynthesis amount, the dry and fresh ratio, and indexes of chlorophyll A, chlorophyll B, carotenoid and the like in the cytochrome are measured and compared, results show that the mixed turf matrix compounded by 300nm rubbish microelement fertilizer and 1-12 percent by weight of crushed rice straws has relatively better effect, can improve the property of the matrix, has a certain nutrition effect, and can ensure that the turf matrix and the root system of the lawn plants have better bonding effect.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and relates to a reasonable and safe use method for composting municipal domestic garbage. More specifically, it is the application of mixed turf substrate in promoting the germination rate of ryegrass. Background technique [0002] In recent years, with the improvement of living standards, the recycling and reuse of domestic waste has become the most promising field and research hotspot in environmental protection. With the continuous improvement of people's living standards, the amount of domestic garbage has also increased accordingly, resulting in a large amount of garbage being unreasonably piled on the edge of the city and occupying a large amount of land resources, which is not conducive to the beauty of the city and is harmful to the human body. extremely adverse effects on health. [0003] Applying domestic waste to the planting of turfgrass is not only conducive to be...
