Description
Technical field
The invention belongs to environmental protection technical field, relate to reasonable, the safe handling method of producing fertilizer from refuse in daily life.Say that more specifically a kind of compounded turf matrix of assembly that mixes is in the application that improves content of festuca arundinacea pigment.
Background technology
In recent years, along with growth in the living standard, the recycling of domestic refuse and recycling problem have become the most promising field in the environment protection, and the focus of research.Along with improving constantly of people's living standard, the quantity of domestic refuse also increases accordingly, therefore caused that a large amount of rubbish is irrational to be stacked in the edge in city and can to take a large amount of land resources, not only be unfavorable for the attractive in appearance of city but also HUMAN HEALTH is brought extremely adverse influence.
Domestic refuse is applied to the plantation of turfgrass, and the space that both being conducive to beautifies the environment depends on us for existence improves, and can reach again the purpose of recovery and the utilization of domestic refuse.Simultaneously, domestic refuse is applied to the plantation on lawn, but can also save out a large amount of anthropogenic soils, agroecosystem is bought go to pot.But domestic refuse has the shortcoming of himself, and the growth on lawn is had its adverse influence.By carrying out assembly with other materials, can weaken rubbish itself to the impact of grass.In addition, because assembly matrix has water retention, can reduce the total water amount, reach water-saving purpose.And have certain nutrient, can self provide nutritive substance.Under northern China arid, semiarid weather, the growth of lawn plant has very large realistic meaning.Therefore, which kind of selects join material and rubbish carries out assembly, which kind of ratio to carry out assembly according to, the relation of domestic refuse between the situation of the growth of the application of lawn matrix and lawn plant had very important meaning.
At present, producing fertilizer from refuse in daily life has certain report as the research that matrix is used for turf establishment.In addition, the thick compost of undressed domestic waste is used in the drought resisting of lawn and is had been reported, but poor effect does not tackle the problem at its root.From existing research, the in the past research for garbage compost focuses mostly in the integral body utilization of thick compost, if extensive like this way prolonged application is in the growth of soil or plant, microenvironment that not only can spoiled soil, and also be disadvantageous for the utilising efficiency that improves resource.If consumer garbage compost is processed the different particle diameter of formation through pulverizer, thereby remove the too much objectionable impurities of accumulation in some particle diameter of compost, be left the compost particle that plant-growth provides nutrient and improves soil physico-chemical property, treated compost is used for the lawn resisting drought saving water, can bring into play advantage organic in the specific particle of compost and that nutritive element is abundant, regulate the physical structure of soil, reach the optimization soil physico-chemical property, the effect of improvement soil.
In view of the foregoing, the inventor carried out utilize garbage waste material carry out the ecological engineering of environment that carpet turf produces research (growth parameter(s) of consumer garbage compost and garden mould matrix turf planting system compares for Zhao Shulan, many vertical peaces etc. ecological magazine, 2008,27; Waste lapping turf planting research take consumer garbage compost as matrix. northwest Botany Gazette, 2007,27).These studies show that: consumer garbage compost is from the angle of plant-growth nutritional needs, can satisfy the requirement of plant-growth, but maximum problem is: the garbage compost quality is loose, this makes matrix be difficult to combine with the lawn plant root system, and such result also makes this technology obtain to use in practice, that is to say that this technical bottleneck can't break through, just mean that this good idea just will lay aside and neglect forever.And in order to solve this key issue, the inventor has launched again to utilize beanstalk, and the research that utilizes sawdust wood chip that linden and birch mix etc. and producing fertilizer from refuse in daily life assembly lawn matrix, purpose so that the matrix of garbage compost assembly can combine with the lawn plant root system well.These results of study show: 1. when utilizing beanstalk and producing fertilizer from refuse in daily life assembly lawn matrix, the lawn plant early growth period has preferably performance { Lian Fei, Zhao Shulan, many vertical peaces, producing fertilizer from refuse in daily life (sieving with 200 mesh sieves) and the compound ecology response as lawn matrix and lawn plant of beanstalk, the agro-environment science journal, 2007,26) }, but the lawn plant growth later stage, when needing lawn plant to set up heavy root system, root growth is suppressed, this phenomenon analogue also once occurred, such as the restraining effect of plant residue to certain class plant in other researchs, its complicated mechanism, this may be relevant with allelopathy, and in addition, the consumer garbage compost matrix that 200 mesh sieves sieve still has the as easy as rolling off a log imagination that splits away off from the root system of plant; And this result of study is finally indicating, utilizes the technological line of crop material and producing fertilizer from refuse in daily life (sieving with 200 mesh sieves) assembly lawn matrix may be difficult to work.2. sawdust wood chip and producing fertilizer from refuse in daily life (sieving with 200 mesh sieves) assembly lawn matrix (the many vertical peaces that ought utilize linden and birch to mix, Zhao Shulan, domestic refuse is produced carpet turf ecological engineering of environment matrix apolegamy research, Chinese Journal of Applied Ecology, 2000,11); Also occurred with the result of " when utilizing beanstalk and producing fertilizer from refuse in daily life assembly lawn matrix " appearance similar, its mechanism is unknown, and this result of study equally also shows, the sawdust wood chip that utilization mixes etc. may be difficult to work with the way of producing fertilizer from refuse in daily life (sieving with 200 mesh sieves) assembly lawn matrix.
In a word, above-mentioned series of studies result gives us a conclusion: solve the loose problem of garbage compost quality if can not find, also just can't solve the difficult problem that combines with the lawn plant root system of matrix; If can not find equally the material of joining of suitable garbage compost lawn matrix, the performance of matrix also can't be improved.The utilisation technology of garbage compost in the mechanism of lawn also just can't obtain to use in practice.As if in a word, because above-mentioned when utilizing beanstalk and producing fertilizer from refuse in daily life assembly compounded turf matrix, effect is not good, and it is impracticable having provided and having utilized the road of stalk assembly garbage compost compounded turf matrix.
