Problems solved by technology

These studies show that: from the perspective of plant growth nutritional requirements, domestic waste compost can meet the requirements of plant growth, but the biggest problem is: waste compost is loose in texture, which makes it difficult for the substrate to combine with the roots of lawn plants, 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 the lawn substrate is combined with soybean straw and municipal solid waste compost, the lawn plants have better performance at the early stage of growth {Lian Fei, Zhao Shulan, Duolian, Municipal solid waste compost (passed through a 200-mesh sieve) sieve) and bean straw are used as lawn matrix and the ecological response of lawn plants, Journal of Agricultural and Environmental Sciences, 2007, 26)}, but in the later stage of lawn plant growth, when lawn plants are required to establish a huge root system, the root growth is inhibited. Similar phenomena have also appeared in other studies, such as the inhibitory effect of plant residues on certain types of plants, and its mechanism is complex, which may be related to other effects. There is an imagination that it is very easy to fall off from the root system of the plant; and this research result finally indicates that the technical route of using crop straw and municipal solid waste compost (sieved with a 200-mesh sieve) to combine the lawn substrate may not be feasible
② When using sawdust mixed with basswood and birch and municipal solid waste compost (sieved with a 200-mesh sieve) to form a turf substrate (Duolian, Zhao Shulan, research on matrix selection for carpet-type turf environmental ecological engineering from 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 loose texture of garbage compost, we can’t solve the problem that the substrate is difficult to combine with the roots of lawn plants; 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

[0074] 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. The compost with a particle size of 1700nm was pulverized at 24000 rpm for 3 minutes to prepare micro-fertilizers with a particle size of 300nm, and the particle size of municipal solid waste compost was analyzed with a S4800 field emission scanning electron microscope (S4800, JAPAN).

Embodiment 2

[0077] Mixing and compounding: the pulverized poplar tomentosa sawdust and 300nm garbage micro-fertilizer are compounded at a weight ratio of 1:6. 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. And changes in plant height and net photosynthesis.

Embodiment 3

[0079] Mixing and compounding: the pulverized poplar tomentosa sawdust and 300nm garbage micro-fertilizer are compounded at a weight ratio of 1:13. 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%. After about 28 days, cut and measure.

Abstract

The invention relates to application of a mixed and compounded turf matrix in promoting growth of festuca arundinacea of lawn plants. 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 crushed Chinese white poplar bits and fined life refuse are compounded to be beneficial to the growth of the festuca arundinacea, all indexes are remarkable and higher than those of a contrast group, wherein the ratios of 28+2, 27+3, 26+4 and 25+5 are relatively better. It proves that the compounded raw materials can improve the property of the matrix, have a certain nutrition function, and 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 an application of a mixed and assembled turf substrate in promoting the growth of lawn plant tall fescue. 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 o...
