| titleOfInvention | Build the method for topsoil in stony desertification earth's surface with heavy metal polluted bed mud |
| abstract | The invention discloses a kind of method building topsoil with heavy metal polluted bed mud in stony desertification earth's surface, comprise the steps: 1) will wait that the stone of renovating earth's surface, stony desertification ground carries out fragmentation, ground grading; 2) river sand is evenly laid in smooth after ground on; 3) heavy metal polluted bed mud is laid on river sand; 4) stabilizing agent is spread on heavy metal polluted bed mud; 5) first time rotary tillage; 6) alternation of wetting and drying process 15 days, is exposed to the sun 7 days, carries out second time rotary tillage, and rotary tillage direction is contrary with second time; After rotary tillage, the mixture quality moisture content of bed mud, river sand, stabilizing agent is reduced to 25 ~ 30% naturally, carries out third time rotary tillage, and rotary tillage direction is vertical with second time; 7) plant leguminous green manure 1 batch after third time rotary tillage, carry out the 4th rotary tillage by green manure also field, after 2 months, obtain topsoil.The topsoil heavy metal stabilization successful that this method obtains, the vegetable crop content of beary metal of plantation meets national standard. |
