The management of the "fish pond-Taiwan" model is to solve the problem of

Analysis of answer D: The "fish pond - platform field" model is a concrete embodiment of the principle of "adapting to local conditions" and belongs to a three-dimensional agricultural structure, that is, digging fish ponds, raising fish and ducks in the water, planting aquatic cash crops; building platform fields

, grow grains, fruits, cotton and feed plants in the fields, and raise livestock and poultry, so as to achieve mutual promotion, three-dimensional development and comprehensive utilization of "fish ponds and Taiwan fields".

It is a management model proposed to address the problem of low-wet depressions that accumulate water in the depressions when rainfall is heavy and the groundwater level rises, causing the depressions to become swampy and the edges of the depressions to become salinized.

Although A, B, and C are all easy to form medium- and low-yielding fields, the use of the "fish pond-platform field" model is not very targeted.
