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.A kind of compounded turf matrix that mixes assembly say so more specifically 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 has become the focus in the most promising field and research in the environment protection with utilizing problem again.Improving constantly of Along with people's standard of living; 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 having helped beautifies the environment depends on us for existence improves, and can reach the purpose of the recovery and the utilization of domestic refuse again.Simultaneously, domestic refuse is applied to the plantation on lawn, but can also practice thrift 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.Through carrying out assembly, can weaken the influence of rubbish itself to grass with other materials.In addition, because assembly matrix has water retention, can reduce the total water amount, reach water-saving purpose.And have certain nutrient, can self nutritive substance be provided.Under northern China arid, semiarid weather, the growth of lawn plant has very big realistic meaning.Therefore, which kind of selects for use join material and rubbish carries out assembly, which kind of ratio to carry out assembly, the relation of domestic refuse between the situation of the growth of the application of lawn matrix and lawn plant had crucial meaning according to.
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 existing report in the drought resisting of lawn, but poor effect does not tackle the problem at its root.From existing research; Research for garbage compost in the past focuses mostly in the integral body utilization of thick compost; If extensive like this way prolonged application in the growth of soil or plant, not only can be destroyed the microenvironment of soil, and also be disadvantageous for improving efficiency of resource.If consumer garbage compost is handled the different particle diameter of formation through kibbler; 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 organic matter and the abundant advantage of nutritive element in the compost particular particles; Regulate the physical structure of soil, reach the optimization soil physico-chemical property, the effect of improving the 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 upright peaces etc. ecological magazine; 2008,27; With the consumer garbage compost is the waste lapping turf planting research of matrix. northwest Botany Gazette, 2007,27).These researchs show: consumer garbage compost is seen 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, and 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 to utilize beanstalk again; And the research that utilizes linden and birch blended sawdust wood chip 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 performance { Lian Fei, Zhao Shulan preferably; Many upright peaces, producing fertilizer from refuse in daily life (sieving) and the compound ecology response of beanstalk, agricultural environment science journal as lawn matrix and lawn plant with 200 mesh sieves; 2007,26) }, but the lawn plant growth later stage; When needing lawn plant to set up heavy root system, root growth is suppressed, and this phenomenon is in other researchs; Analogue also once occurred, like the restraining effect of plant residue to certain type of plant, its mechanism is complicated; This maybe 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 from the root system of plant, splits away off; 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 possibly be difficult to work.2. ought utilize linden and birch blended sawdust wood chip and producing fertilizer from refuse in daily life (sieving) assembly lawn matrix (many upright peaces with 200 mesh sieves; 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, utilizes the blended sawdust wood chip etc. and the way of producing fertilizer from refuse in daily life (sieving with 200 mesh sieves) assembly lawn matrix possibly be difficult to work.
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 the material of joining of suitable garbage compost lawn matrix equally, 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.
