Problems solved by technology

In the remediation process, multiple methods need to be used in combination, so the corresponding remediation system should be improved. A single soil heavy metal pollution treatment method is often impossible to implement due to high cost, unsustainability, or even neglecting the other.

Embodiment Construction

[0016] The specific implementation methods of the rice field comprehensive planting and breeding technology to repair soil heavy metal pollution are as follows:

[0017] 1. Paddy field reconstruction, deep soil plowing: open ditches on three sides around the paddy field (leave one side to facilitate mechanized cultivation), the ditches are 100-150cm deep, 200-300cm wide, slope ratio 1:2.5, and deep can be opened in the middle of paddy fields of more than 6 mu 60-80cm, 50-60cm wide one-shaped ditch, cross ditch or well-shaped ditch are connected with the surrounding ditch, the total area of ​​the fish ditch is controlled not to exceed 15-20% of the paddy field area, the planting area is plowed 15-20cm deep, and the ridge is reinforced . The soil for excavating the circular ditch can be piled up on the periphery to build a field ridge and compacted, heightened, widened, and reinforced to ensure that the field ridge is 0.6 to 0.8 meters above the field surface and the top is abou...

Abstract

A method of ecologically restoring heavy meatal contamination of soil by a ricefield integrated breeding-planting technique relates to major technical innovations in the field of treatment of heavy metal contamination of soil and is characterized in that the production steps, such as ricefield reformation, fertilizer application, disinfecting and field management, of the ricefield integrated breeding-planting technique are implemented to arrive at ecological restoration for heavy metal contamination of soil; the method belongs to scientific application of the ricefield integrated breeding-planting technique in the field of treatment of heavy metal pollution of soil; the problem is solved that existing methods of treating heavy metal contamination of soil are high in cost, zero in output, unsuitable for continuation or copying, low in public participation and even unable to be implemented due to the failure of multiple attendance; the method is truly an ideal restoration mode that is environmentally friendly and energy efficient, has lasting restoration effect, can restore land yield to higher level, and is convenient to popularize and easy to perform.

Description

technical field [0001] The technical invention relates to an important technical innovation in the field of soil heavy metal pollution control, and is a comprehensive technical application in the field of agricultural production. Through the scientific use of comprehensive planting and breeding technology in the field of agricultural production, the effect of solving the ecological restoration of heavy metal pollution in rice field soil can be achieved, and at the same time, it can solve the problems of high cost of heavy metal pollution restoration and treatment, unsustainable, difficult to promote the model, and restoration of land output. The series of problems is a major change in the method of heavy metal pollution control, and it is also a breakthrough in the directional thinking of comprehensive environmental governance. Background technique [0002] At present, there are many restoration methods for soil heavy metal pollution control, among which physical restoration...
