Abstract
The present invention discloses preparation of a soil heavy metal contamination treatment biological preparation, and a green ecological restoration project. According to the treatment restoration project, the biological preparation and the green ecological restoration project are used to perform in situ soil restoration from the source so as to solve the heavy metal contamination and eliminate the heavy metal hidden danger; and during the planting process, with the combination with crop growth, the biological preparation and the green ecological restoration project are used, such that the fertilizer applying and the pesticide applying are reduced while the absorption of plants on heavy metals is reduced so as to ensure the food safety from the source, ensure high-quality, safe and high-yield of agricultural products, and promote sustainable development of the green ecological agriculture.
Description
Technical field
The present invention relates to a kind of preparation and green ecological recovery project of administering the biotechnological formulation of heavy metal pollution of soil, belong to agro-biological engineering class.
Background technology
For many years, China's economic, while fast development, also brings the pollution of environment, especially on the impact of agroecological environment, according to the parties concerned, the whole nation 1,800,000,000 mu of arable lands, have 1.5 hundred million mu contaminated by heavy metals, account for 8.3% of cultivated area.Heavy metal contamination farmland directly affects grain security and food safety, affects the livelihood of every family.Grain security and food safety must be done from source, and therefore, administer heavy metal pollution of soil green ecological and repair farmland, the sixth of the twelve Earthly Branches is extremely urgent.Although many experts and scholars propose various administering method, for this special ecotope in farmland, by general physics, chemical process, be difficult to thoroughly more control.For this reason, people wish a kind of effective method, are separated by heavy metal pollution of soil from farmland, eliminate the hidden danger that heavy metal exceeds standard in grain and food, be up to state standards the content allowed, thus hold the pass of grain security and food safety from source.
Summary of the invention
The object of the invention is for solving the problem, a kind of preparation and the green ecological recovery project of administering the biotechnological formulation of heavy metal pollution of soil provided.
For achieving the above object, the invention also discloses the preparation of administering heavy metal pollution of soil biotechnological formulation.

According to aforementioned proportion: by chitosan 0.1 ~ 0.2 part, be dispersed in 85-95 parts of water, then add 8-12 parts of citric acids and be heated to 80 DEG C of dissolvings, add humic acids, stir and be cooled to 45 DEG C, add composite flora and ferment 8 hours.
Soil regulates a preparation for sorbent material, it is characterized in that: produce (weight percent) by following proportioning
According to the above ratio, successively sepiolite, wilkinite, calcium carbonate, potassium humate are mixed and can pack.
A preparation for mineral thalline sorbent material, is characterized in that: produce (weight percent) by following proportioning
(Bacillus Lateyospoye) ， Department is that product is bought, living bacteria count (cfu/ gram) 3,000,000,000/gram in market to described Bacillus Lateraporus.
According to aforementioned proportion: with 5 ~ 6 parts of Bacillus Lateraporus, fully mix with 15 ~ 20 parts of citric acid thalline after, then after mixing with 20 ~ 30 parts, diatomite, sepiolite 30 ~ 35 parts, zeolite powder 20 ~ 25 parts.
A preparation for Tiny ecosystem biotechnological formulation, is characterized in that: produce (weight percent) by following proportioning
Described fruits and vegetables starter is the preparation of fruit and vegetables hybrid anaerobic fermentation.
According to aforementioned proportion: by 1.0 ~ 1.5 parts of chitosans, be scattered in 60 ~ 80 parts of water, then add 0.5 ~ 1 part of lactic acid, 1 ~ 2 part of citric acid, dissolve chitosan, be heated to about 80 DEG C, limit heating edge is dissolved, until vitreous state, is then cooled to about 30 DEG C, add fruits and vegetables starter, ferment 24 hours.
Invention further provides the constructional method of administering heavy metal pollution of soil green ecological preparation for repairing.
A kind of constructional method of administering the soil green ecological preparation for repairing of heavy metal contamination.
1. before turn in farmland, first detect heavy metals in farmland content, pH value, understand pollution level.
2. according to pollution level, use biological chelating, every mu of 3 ~ 5kg.Pollute the lighter's Shaoshi, pollute severe one and execute more.Then turn over, discharge water immersion 3 ~ 5 days, a trench digging point railway carriage or compartment draining, draining furrow width 50 centimetres, dark 30 centimetres.
3. by the draining containing heavy metal, in suction bio-processing container, first low rate mixing (per minute 20 turns), throw in biological flocculant while stirring, rapid stirring (per minute 80 turns) 1 minute after 2 minutes, at once stop stirring, after static 15 minutes, by throw out and throw out filtered and recycled.Water after filtration, then row utilizes.
4. farmland is by after 1 ~ 2 washing, and sampling Detection soil, heavy metal content in soil is up to state standards, and no longer washs.
5 for soil up to standard after washing, and the every mu of adjustment sorbent material 5kg that is manured into soil, balanced soil nutrition, regulates pH value, get final product Planting Crops.
6., for rice field, every mu of rice field 5kg mineral thalline sorbent material and base manure are mixed thoroughly, apply in farmland together.
7., at seedlings of cereal crops growing period, every mu sprays emblem ecologic biological preparation 500mL, and wherein seeding stage sprays 50mL, sprays 200mL before rice tillering, sprays 250mL during Qi Sui 20%.
Specific embodiment
Example one, green ecological Rice Cropping
2013, in Shi Jing village, Shuan Jiang town, Changsha County, 500 mu, plantation green ecological paddy rice, have employed above-mentioned implantation methods.According to Shuan Jiang town Shi Jing village heavy metal contamination situation, belong to local slight pollution.Therefore, in the specific implementation, only when ploughing, every mu of rice field is first manured into soil and regulates sorbent material 5kg, balanced soil nutrition adjustment pH value.Then use 5kg mineral thalline sorbent material by every mu, apply together with base manure in rice field, spray a 50mL emblem ecologic biological preparation seeding stage every mu, before tillering, every mu sprays 200mg emblem ecologic biological preparation, and during the neat fringe 20% of the seedlings of cereal crops, every mu sprays 250mL emblem ecologic biological preparation again.
During results, paddy is full, setting percentage is high, increases production 15.8% on year-on-year basis, heavy metal, agriculture is residual does not all exceed standard, especially heavy metal cadmium, and through limited liability company of grain group of Hunan Province, warehouse-in detects, cadmium content 0.08mg/kg, is significantly less than national standard permissible value 2mg/kg.
