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

The invention provides a method for ecological restoration of soil heavy metal pollution by a rice field comprehensive planting and breeding technology, and relates to an important technical innovation in the field of soil heavy metal pollution treatment. According to the method, an implementation process of production links such as rice field reconstruction, fertilization, disinfection and fieldmanagement of the rice field comprehensive planting and breeding technology is adopted, so that the ecological restoration of the soil heavy metal pollution treatment achieves a satisfactory effect. The method is scientific application of the rice field comprehensive planting and breeding technology in the field of soil heavy metal pollution treatment. The problems of high cost, no output, unsustainability, irreproducibility, low public participation and even incapability of implementation of the current soil heavy metal pollution treatment method are solved, and the method is an ideal restoration mode which is truly environment-friendly and energy-saving, lasting in restoration effect, capable of improving the output of restored land, convenient to popularize and easy to operate.

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...
