Abstract
The invention discloses a method for improving a mountainous region with copper exceeding standards through plants. The method comprises the following steps that tea seed powder and charcoal are applied to the mountainous region with the copper exceeding the standards, and after the mountainous region is ploughed according to a conventional method, ailanthus and Chinese pennisetum are planted; during planting, planting holes are formed for the ailanthus according to the planting density that the planting spacing ranges from 1.5 m to 2.5 m, and 2 to 3 Chinese pennisetum planting holes are formed between every two plants of ailanthus; after planting, harvesting can be carried out once when the plant height of the Chinese pennisetum reaches 80 cm to 100 cm, and urea of 10 kg to 20 kg is applied per mu after harvesting of every time; and after the ailanthus is planted, the position 1 m high of each branch is cut once in winter every other year, and every cut branch head is coated with a plastic film. According to the method, the ailanthus and the Chinese pennisetum which are high in survival ability, high in breeding speed and fast in growth cycle are selected, the planting density is reasonably arranged, and after planting, the severe copper metal contamination environment is managed.
Description
Technical field
The present invention relates to biotic environment recovery technique field, the especially a kind of side in the exceeded mountain region of utilization plant improvement copper
Method.
Background technology
Soil is the important component part of environment, is the important natural resourcess that human society is depended on for existence.With economy
The increase of fast-developing and population, soil and mountainous exploration become the urgent content due to many mountain region heavy metal coppers and seriously surpass
Mark, is not suitable for the growth of agriculture and forestry plant, should not more make the plantation of crops, and Planting Crops can be enriched in plant body and pass through
Food chain enters human body, seriously threatens human health, therefore the improvement in the mountain region of the content severe overweight of heavy metal copper to carve not
Rong Huan.
Using plant heavy metal enrichment or absorb, the content of the heavy metal copper in mountain soil can be removed
Excessive problem, this technology are called plant extract rehabilitating soil technology.Plant extract rehabilitating soil technology is used as a kind of emerging
Green, environmental and ecological biotechnology, can keep Soil structure and microorganism to live in the presence of ecological environment of soil is not destroyed
Property situation under, directly substantial amounts of pollution element is absorbed by the root system of plant, is transferred in plant stem-leaf, and in addition profit
With, reach and heavy metal is taken away from soil, the purpose of improvement contaminated soil.Therefore, how to change good copper content using plant to surpass
Mark mountain region is current study hotspot.
The content of the invention
The present invention is directed to mountain soil heavy metals exceeding standard problem, there is provided a kind of side in the exceeded mountain region of utilization plant improvement copper
Method., by planting ailanthus altissima (mill.) swingle and Herba penniseti, Adsorption of Heavy Metals copper is improving mountain soil for the method.
In order to realize object above, the technical solution used in the present invention is as follows：
A kind of method in the exceeded mountain region of utilization plant improvement copper, comprises the following steps：
（1）Choose the exceeded mountain region of cupric and improved the mountain region for agricultural；
（2）Camellia oleosa seed powder and charcoal are put on the exceeded mountain region of cupric, behind mountain region of turning over according to a conventional method, plantation ailanthus altissima (mill.) swingle and
Herba penniseti；Ailanthus altissima (mill.) swingle is opened into kind of a plant hole according to the planting density that seeding row spacing is 1.5-2.5m during plantation, in overcast and rainy routinely side
Method is planted, and opens 2-3 caves Herba penniseti kind plant hole between 2 plants of ailanthus altissima (mill.) swingles, and the wherein height of seedling of ailanthus altissima (mill.) swingle is 80-100cm, the height of seedling of Herba penniseti
For 10-15cm；
（3）By after plantation, the plant height of Herba penniseti often reaches 80-100cm, once, after gathering in every time, per mu applies 10- again for harvesting
The carbamide of 20kg；Ailanthus altissima (mill.) swingle plantation cut bar once in winter every 1 year at tree trunk is high 1 meter, and cut head with plastic film wrapped.
Preferably, the exceeded mountain region of above-described copper is for Copper In The Soil content >=200mg/kg.
Preferably, the consumption of the above camellia oleosa seed powder and charcoal is the weight of every mu of 200-300kg, camellia oleosa seed powder and charcoal
Amount is than being 1:3-5.
Preferably, after the exceeded mountain region improvement of the copper reaches standard of soil environment quality, seeding row spacing will be moved between ailanthus altissima (mill.) swingle
2m × 3m builds economic forest, or all transplants, and recovers proportion of crop planting, or routinely planting forage grass.
Compared with prior art, advantages of the present invention and have the beneficial effect that：
1st, survival ability is strong, reproduction speed is fast, the ailanthus altissima (mill.) swingle that growth cycle is fast and Herba penniseti by selecting for the inventive method, rationally pacifies
Seeding density in planting, after plantation, the exceeded mountain region of severe copper is governed, and solves that copper at this stage is exceeded to cause plant short and small, raw
Thing amount is little, the problem that environment remediation effect is poor.
2nd, the inventive method can improve the life of copper metal by putting on the exceeded mountain region of copper with camellia oleosa seed powder and charcoal
Thing effectiveness, and then promote the absorption of plant heavy metal, repair time is greatly shortened, the efficiency of modification is improved.
3rd, the inventive method administers the exceeded mountain region of copper using function phytobiocoenose, is green original flavor reparation, does not result in
Secondary pollution, governance process will not destroy original ecological environment, be finally reached recovery fertility, promote regional landscape and
Humorous, ecological balance and the long-term goal of sustainable development.
4th, this method planted ailanthus altissima (mill.) swingle and Herba penniseti after 2 years, and the copper removal amount of soil reaches more than 95%.
