摘要

半干旱地区的特点是极端高温，这限制了土壤保持水分的能力，从而影响了农业生产。本研究的目的是研究覆盖对巴西半干旱区滴灌香蕉种植园土壤温度和湿度的影响。采用6个热电偶和3个土壤湿度探头，椰壳为地膜。比较了两种覆盖密度(4和8 t ha-1)和裸土白天和夜间的地表温度。研究时间为2014年11月至2015年3月，测量了0.1、0.3和0.5 m三个深度的土壤温度和湿度。地膜对土壤温度波动具有缓冲作用。与地膜相结合的滴灌管理提供了接近田间容量的均匀水分剖面。

Assessing soil temperature and moisture fluctuations under irrigated banana (Musa spp.) cultivation in response to coconut coir mulch cover

The semiarid is characterized by extreme heat, which affects agricultural production by limiting the soil's ability to retain water. The objective of this study was to investigate the influence of mulch on soil temperature and soil moisture in a drip irrigated banana plantation in a Brazilian semiarid region. Six thermocouples and three soil moisture probes were used, with coconut coir as mulch. Daytime and nighttime surface temperatures were compared for two mulch densities (4 and 8 t ha-1) and bare soil. Soil temperature and moisture were measured at three depths (0.1, 0.3 and 0.5 m). The study was conducted from November 2014 to March 2015. Mulch had a buffer effect on soil temperature fluctuation. Drip irrigation management associated with mulch provided a uniform moisture profile close to field capacity.
