Abstract

Abstract:

With a developed root system, Cyperus esculentus has great potential as a windbreak and sand-fixing crop in the farmland ecosystem. Cyperus esculentus models are important for obtaining more ecological and economic benefits by investigating the change of wind flow field and windbreak efficiency of different harvesting distances. We established three trip-harvesting distance models: harvest one belt interval one belt (H1), harvest two belt interval one belt (H2), and harvest three belt interval one belt (H3). We measured the flow field structure, wind speed acceleration rate, and windbreak efficiency of the three models at 6 m·s^-1, 8 m·s^-1, and 10 m·s^-1 wind speed rates. The results are as follows: (1) The wind speed decreases rapidly because of the resistance of the three plant models, resulting in the formation of a wind shadow area in the ground layer. The stability and wind shadow areas of H2 and H3 are greater than those of H1. (2) An increase in the wind speed acceleration rate decreases windbreak efficiency. The windbreak efficiency of H2 and H3 on the leeward side is significantly higher than that of H1, but there is no significant difference in windbreak efficiency between H2 and H3. In the harvest area, the windbreak efficiency of H2 and H3 is >50%, whereas that of H1 is <40%. (3) There is no significant difference between the H2 and H3 models in terms of windbreak and sand-fixation benefits. However, the harvest spacing of H2 is less than that of H3, as are the economic benefits. Thus, considering the ecological and economic benefits, H3 is the recommended harvesting method.

Key words: harvest spacing, wind tunnel test, flow field structure, wind speed acceleration rate, windbreak efficiency
