Phyto-mycorrhizal restoration Mulberry/mulberry + arbuscular mycorrhizal fungi; leguminous plants + rhizobia

(2) Determination of soil cultivation technology

Since the soil in treatment area A is not polluted, soil remediation is not required, so the “plant-mycorrhizal remediation” technology in the generalized configuration results is removed; secondly, the soil fertility in treatment area A is not high, and soil improvement is required, so keep "Green manure plants" in the generalized configuration results.

(3) Determination of water-saving technology

Due to the frequent occurrence of droughts in the treatment area A, drinking water for humans and animals is difficult, and water-saving technology is required, so the generalized configuration results include "biological coverage and moisture conservation/seeding-raising seedlings for drought resistance//deficit-regulating irrigation//small pipe outflow irrigation-low-pressure pipeline water delivery ".

(4) Determination of water conservancy projects

Due to the difficulty in irrigating slope cultivated land in the treatment area A, it is necessary to configure the slope water system project, so the "sediment retention and drainage - water collection and storage - water diversion and water supply technology" in the generalized configuration results are retained; secondly, there is no flood disaster in the treatment area A, Depression flood drainage works are not required, so the "sink hole treatment" in the generalized configuration results is removed.

(5) Confirmation of energy engineering

Due to the lack of energy in the rural area of governance area A, energy engineering needs to be configured, so the "biogas technology/energy-saving technology" in the generalized configuration results is retained.

After the above detailed configuration steps, the final configuration results are shown in Table 3 and Table 4 below.
