摘要

Sorghum (Sorghum bicolor L. Moench) has been recognized as an alternative energy crop cultivated for biomass which used as a raw material in production of syrup or dry matter. In Central Greece (Velestino, Volos) its main growth period coincides with the dry season and irrigation is needed for reasonable biomass production. The objective of this work is to research the biomass production under intelligent irrigation methods using surface and subsurface drip irrigation systems. Experiments were carried out during 2007 cultivating period. Three irrigation treatments: I50, I70, I100 corresponding to the water supply, surface (DI) and subsurface (SDI), of 50% of daily evapotranspiration (ETd), 70% ETd, 100% ETd, respectively, were experimented with each other and with a fourth complete automated one (AI100). The daily water needs were determined by an A class evaporation pan. The AI100 treatment included soil moisture sensor which measured the fluctuation of moisture content. The amount of water was equal to 100% ETd and irrigation time lasted until soil moisture content rose from 70% to 100% of field capacity. Maximum above ground dry biomass was 42.88Mg/ha in subsurface treatment SDI100. The total dry biomass production and the water use efficiency were affected.

Moench）已被认为是用于生物质的替代能源作物，其用作生产糖浆或干物质的原料。在希腊中部（Velestino，Volos）其主要的生长期与干燥季节一致，需要合理的生物质生产需要灌溉。这项工作的目的是使用表面和地下滴灌系统研究智能灌溉方法下的生物质生产。实验是在2007年培养期间进行的。三种灌溉处理：I50，I70，I100对应于供水，表面（DI）和地下（SDI），每日蒸散（ETD），70％ETD，100％ETD的50％，彼此实验并具有第四个完整的自动化（AI100）。每日水需求由一类蒸发锅确定。 AI100处理包括土壤湿度传感器，其测量了水分含量的波动。水的量等于100％ETD，灌溉时间持续直到土壤水分含量从现场容量的70％上升至100％。在地下处理SDI100中，最大地干生物量为42.88mg / ha。干生物质总产量和水使用效率受到影响。
