Abstract
The invention discloses a seedling raising substrate for wind prevention and sand fixation plants. The seedling raising substrate is prepared from municipal sludge and biomass charcoal in such a manner of aerobic composting. The invention also provides a preparation method of the seedling raising substrate. The seedling raising substrate for the wind prevention and sand fixation plants is prepared by carrying out aerobic composting on the raw materials (municipal sludge and the biomass charcoal) and adding a certain quantity of water-retaining agent and plant growth regulator to the raw materials; the seedling raising substrate is rich in nutrient elements such as organic matters and nitrogen phosphorus and potassium, and also has strong microbial activity; the plants cultivated by use of the seedling raising substrate have prosperous root systems; the substrate is applied during transplanting so that the rejuvenation period of the transplanted plants can be shortened and the survival rate of the transplanted plants can be increased; in short, the seedling raising substrate is highly suitable for afforestation and grass planting on difficult sites such as droughty desert areas.

Technical field
The present invention relates to municipal sludge and agricultural organic waste recycling field, be specifically related to seedling medium of a kind of plant of checking winds and fixing drifting sand and preparation method thereof.
Background technology
Along with the expansion of city size and the increase of municipal sewage plant's number, all a large amount of municipal sludges can be produced every year.These mud due to heavy metal element and virus causing disease body burden higher, direct use can bring serious problem of environmental pollution.Carrying out aerobic composting process to mud can heavy metal element in stabilized sludge, and the virus can killed in mud and pathogenic bacteria, make mud reach the requirement of second stage employ.Owing to containing the nutritive elements such as abundant organic matter and N P and K in mud, and mud is cheap and easy to get, mud is used for afforestation and afforestation is an important outlet of current mud, nutritive element in mud can promote the growth of plant, and abundant organic matter can play the effect of improvement soil.
Biomass charcoal is a kind of material containing carbon rich formed under the condition of anaerobism pyrolysis by the material of carbon containing, biomass charcoal is used as soil improvement agent, many-sided beneficial effect can be produced to soil, it can improve soil to the confinement capabilities of nutritive element and cation exchange capacity, reduce toxic element to the toxicity of plant, improve the utilization ratio of soil nutrient, strengthen the water retention capacity of soil, improve Soil structure and other physical properties, promote the development of microbial populations in soil and strengthen the activity of soil microorganisms, reduce the leaching loss of soil nutrient, promote the circulation of soil nutrient, and the content of soil organic matter can be increased, thus the growth of plant can be promoted.
In recent years, due to the destruction of vegetation and the denudation of forest, cause China's Desertification area expanding day, for the plant of checking winds and fixing drifting sand often because land occupation condition is poor, after transplanting, surviving rate is lower, therefore, the transplanting survival rate improving plant of checking winds and fixing drifting sand is the key factor playing its sand break and fixation function.
Summary of the invention
Object of the present invention is exactly for the low defect of plant transplantation surviving rate of checking winds and fixing drifting sand in above-mentioned prior art, provides a kind of cheap and easy to get, can improve the seedling medium of plant transplantation surviving rate of checking winds and fixing drifting sand.
To achieve these goals, technical scheme provided by the invention is: the seedling medium of a kind of plant of checking winds and fixing drifting sand, and is to be prepared by the mode of aerobic compost with municipal sludge and biomass charcoal.
Second object of the present invention there is provided the preparation method of the seedling medium of above-mentioned a kind of plant of checking winds and fixing drifting sand, be by municipal sludge, biomass charcoal and 0.1% fermenting agent mix laggard row aerobic compost, crushing material after becoming thoroughly decomposed crosses 2mm sieve, the mode of spraying is utilized evenly to spray into the wood vinegar that concentration is 20mg/kg ~ 40mg/kg, finally mix the particulate state water-holding agent of 0.1%, after mixing.
Further, the preparation method of the seedling medium of above-mentioned a kind of plant of checking winds and fixing drifting sand, in described seedling medium, containing the municipal sludge counting 50% ~ 70% according to weight percent, count the biomass charcoal of 50% ~ 30% according to weight percent, count the water-holding agent of 0.1% according to weight percent.
Further, the preparation method of the seedling medium of above-mentioned a kind of plant of checking winds and fixing drifting sand, municipal sludge is the mud after city sewage plant dehydration and drying, crosses 2mm sieve and obtain after pulverizing; The preparation method of biomass charcoal is take agricultural crop straw as raw material, adopts biomass carbonizing furnace, and prepare under the condition of anaerobism pyrolysis and cross 2mm sieve, anaerobism pyrolysis temperature is 300 DEG C ~ 500 DEG C.
Further, the preparation method of the seedling medium of above-mentioned a kind of plant of checking winds and fixing drifting sand, described aerobic composting process is: will cross the municipal sludge after 2mm sieve, biomass charcoal and 0.1% fermenting agent fully mix, adjustment water content is 50% ~ 60%, pile bar heap in echelon and carry out aerobic fermentation, trapezoidal bar heap bottom width 2m, top width 1m, high 1.5m, period was stirred once every 5 days, and measuring tempeature and water ratio, according to the leavening temperature determination fermentation ends time, after having fermented, compost is air-dry, pulverized 2mm sieve, the wood vinegar of 20mg/kg ~ 40mg/kg is added with spray pattern, finally add the particulate state water-holding agent of 0.1%, mix.
Beneficial effect of the present invention is: the seedling medium of a kind of plant of checking winds and fixing drifting sand provided by the invention, for raw material with municipal sludge and biomass charcoal, add that a certain amount of water-holding agent and plant-growth regulator make through aerobic compost, this seedling medium contains the nutritive elements such as abundant organic matter and N P and K, and there is stronger microorganism active, the root system of plant that this seedling medium is cultivated is flourishing, apply this kind of matrix when transplanting simultaneously, the plant seedling-slowing stage after transplanting can be made to shorten, surviving rate improves, be well suited for the afforestation grass planting on the Difficult site such as the desert area of arid.
