Abstract

Based on the various agro-edaphic and agro-climatic characteristics, the suitability of maize cultivation during winter season has been determined in Cox’s Bazaar Sadar Upazila. For this purpose, under the existing climate conditions, considered agro-edaphic factors of various geomorphic units are soil permeability, effective soil depth, available soil moisture, soil reaction (pH), soil salinity, slope etc. Long-term climate attributes of the study area were used to determine the overall climate suitability classes, and the combined land suitability classes for maize (rabi) cultivation have been determined through the adjustment of the agro-edaphic and agro-climatic suitability criteria. Thus, recognized combined land suitability classes for maize (rabi) cultivation in the present study area are ‘highly suitable’, ‘suitable’, and ‘moderately suitable’. A total of 896 hectares land has been found as ‘highly suitable’ for maize cultivation in Cox’s Bazaar Sadar Upazila while approximately 4403 and 11,000 hectares have been identified as ‘suitable’ and ‘moderately suitable’, respectively.

孟加拉国考克斯巴扎市Sadar Upazila玉米种植土地适宜性评价

根据各种农业土壤和农业气候特征，确定了考克斯巴扎Sadar Upazila冬季玉米种植的适宜性。为此，在现有气候条件下，考虑各种地貌单元的农业土壤因子有土壤渗透性、土壤有效深度、土壤有效水分、土壤反应(pH)、土壤盐分、坡度等。利用研究区长期气候属性确定了总体气候适宜性等级，并通过调整农业土壤和农业气候适宜性标准确定了玉米(rabi)种植的综合土地适宜性等级。因此，本研究区公认的玉米(rabi)种植的土地适宜性等级为“高度适宜”、“适宜”和“中等适宜”。在Cox ' s Bazaar Sadar Upazila，共有896公顷的土地被认定为“非常适合”玉米种植，而大约4403公顷和1.1万公顷的土地分别被认定为“适合”和“中等适合”。Asiat。Soc。中国科学，44(1):35-51,2018年6月
