Detailed description of the invention
Embodiment: test plot is divided into 8 regions, including 2 clear areas and 6 trial zones, every 2 of 6 trial zones be a component are 3 groups, often organize respectively according to every mu of 1000kg(DS1000), 2000kg(DS2000), 3000kg(DS3000) use described microbe soil organic substrate, adopt Shen Di gardens Nutrition Soil as comparison.Method particularly includes: Nocard's bacillus, bacillus acidophilus and bacillus subtilis are weighed as microbe soil organic substrate, add in the organic substrate obtained after greening garbage (leaves, branch etc.) carries out aerobic fermentation with changing food waste in proportion, uniformly puddle in the soil of test plot by machinery operation, and be suitably humidified as required, plant after 15 days；Wherein work machine is giant caterpillar formula engineering machinery, is transported to trial zone with flat car, and additionally domestic digging machine does to coordinate and completes original soil reparation in position, and the day hack ability of machine is: 250-350 cube of soil, soil grinding particle size is: 5-25mm.After crop growth period terminates, taking pedotheque and detect, the overall test cycle is about 5 months.
Result of the test:
The equal multi-point sampling of regional, pH value, have matrix content, total nutrient content by compose Buddhist nun test, content of beary metal entrust Shanghai City academy of agricultural sciences detect.
1.pH value is tested
Blank group: 8.72
DS1000:8.43
DS2000:8.56
DS3000:8.71
Matched group: 8.56
Each test group is after less than the process of 5 months, and compared with blank group, soil pH all shows downward trend.
2. there is matrix content detection (weight percent hundred)
Blank group: 0.806%
DS1000:1.81%
DS2000:1.52%
DS3000:1.09%
Each test group there is matrix content all to rise to some extent, and the most obvious with DS1000 group.
3. total nutrient content detection (mg/kg, by N, P, K summation meter)
Blank group: 0.278
DS1000:0.309
DS2000:0.362
DS3000:0.339
In each test group, total nutrient content all rises to some extent, and the most obvious with DS2000 group.
4. shown in the following form of content of beary metal detection (mg/kg)
5. the soil texture and geobiont are observed
The original soil of pilot region is before reparation, biological variety and quantity are very low, substantial amounts of various geobiont is occurred in that in the repairing test stage, including substantial amounts of Aranea, Big Formica fusca, locust, Bufo siccus, Aeschna melanictera and part Lumbricus etc., soil occurs in that the mycelium not having in original soil, although only having repair time 10 months, but the sedimentation of soil is significantly improved.
The present invention adds microbe soil remediation microbial inoculum by plant equipment in proportion in original soil and yellow ground is uniformly puddled; microbe soil repair materials contains substantial amounts of soil probiotics; the indigenous microorganism in soil can be activated; by metabolism and amplification; probiotics content in soil is greatly increased and occupies advantage; can effectively suppress the harmful levels of pathogens in soil; the pH value (being particularly conducive to the growth of the happiness acid trees such as oriental cherry, Semen Ginkgo, red maple) of original soil, the overall vigor improving soil can be reduced.On the other hand, soil, by mechanical activation comminution, has been carried out oxygenation and ultraviolet disinfection by the present invention, improves the oxygen content of soil, and ultraviolet has killed substantial amounts of harmful bacteria in soil effectively simultaneously；It is effectively increased the soil property of original soil after process, is conducive to the root of hair of trees and flowers and plants, is conducive to the sprouting of shoot, young leaves.
Practical situation for the low and existing planting technique soil poor quality of original soil utilization rate, mechanization original soil and existing urban afforestation planting soil is carried out in-situ immobilization, can effectively pulverize the soil hardened, remove the green brick in a large amount of soil and impurity, soil is smashed, oxygenation and ultraviolet disinfection, improve crumb structure and the purity of soil, by mixed microorganism organic substrate in soil in proportion, function probiotics contained in microbe organic matrix is made to produce metabolism and amplification with indigenous microorganism, improve breathability and the sedimentation of soil, green brick in removing soil and other impurity, improve the crumb structure of soil, the purity of recovery and raising soil and vigor are simultaneously, can also effectively reduce the acid-base value of soil and relevant heavy metal analysis value, after making reparation, the indices of original soil reaches the industry standard (CJT340-2011) with compound afforestation planting soil.Therefore, this technology, while solving the existing quality problems of urban afforestation planting soil, also solves the practical problems such as environmental protection and huge waste that in real estate development of the city process, the outward transport of a large amount of original soils causes.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention.Claimed scope is defined by appending claims and equivalent thereof.
