Abstract

    The purpose of this study was to use of environmental-friendly cropping rotation model to achieve due to climate change and increasing food self-sufficiency. In the northern region will be two cropping rice pattern planning into a rice, autumn crop dry farming (groundnut, corn and sweet potatoes) farming model, the results showed rice cultivation can reduce pesticide application rate, upland is adopted without (low) site preparation tillage practices to achieve the sustainable use of agricultural land and water environment field rotation affinity business model; explore different fertilizer effects on crop growth and soil environment of the central region, showed that rice- vegetables-wheat rotation can reduce the amount of fertilizer to achieve both production and the environment ; the southern region to explore the economic benefits of different upland cropping patterns, the results are displayed in Job's tears-green manure sesbania-sesame crop rotation patterns of hectares up to a net gain; eastern region to explore the different inputs of fertilizers and pesticides impact of floods, droughts and crop rotation, the results show can reduce fertilizer and pesticide inputs, use repellent and non-crop pesticide prevention act to achieve environmental affinity upland rotation model.

Keywords: Crop Rotation, Environmental Friendly Cropping System.
