【摘要】：为了进一步明确玛纳斯河流域土壤质地对机采棉水热状况及生长发育的影响,通过测坑试验,对3种不同土壤质地(壤土、砂土、黏土)下的土壤温度、土壤含水率、机采棉、株高、叶面积及产量进行了对比分析。结果表明,不同土壤质地条件下地温日变化及不同时间段温度增量表现为:砂土黏土壤土;不同土壤质地条件下0~60 cm和0~100 cm土层土壤质量含水率大小顺序为:黏土壤土砂土;不同土壤质地下机采棉的生长及产量均表现为壤土黏土砂土。研究认为壤土质地种植机采棉,提高了其生育前期的土壤温度,有效保持了土壤水分,有利于其生长发育。因此,为了提高水分利用效率及产量,建议玛纳斯河流域应增加壤土质地种植机采棉的比例。
[Abstract]:In order to further clarify the effect of soil texture on water and heat status and growth and development of mechanized cotton in Manas River Basin, soil temperature, soil moisture content and cotton harvesting under three different soil textures (loam, sand and clay) were measured by pit test. Plant height, leaf area and yield were compared and analyzed. The results showed that the diurnal variation of soil temperature and the temperature increment in different time periods under different soil texture conditions were as follows: sandy clay loam, soil quality moisture content of 0 ~ 60 cm and 0 ~ 100 cm soil layer under different soil texture conditions were in the order of clay loam sandy soil. The growth and yield of cotton picking under different soil textures were shown as loam clay sand. The results showed that the soil temperature was increased and soil moisture was maintained effectively, which was beneficial to the growth and development of loam soil. Therefore, in order to improve water use efficiency and yield, it is suggested that the proportion of loam texture planter should be increased in Manas River Basin.
