Application of mixed turf matrix in drought resistance of lawn plants

Abstract

The invention relates to application of a mixed and compounded turf matrix in improving the drought resistance of lawn plants, wherein the mixed turf matrix is compounded by 300nm rubbish microelement fertilizer and smashed Chinese scholartree bits in weight part ratio of respectively 28:2, 27:3 and 26:4. It proves that the compounded raw materials can improve the water holding 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 the application of a mixed turf substrate in the drought resistance of turf plants. 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 beaut...

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, the mechanism of which is complex, which may be related to the sensory effect. 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 (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 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
