【摘要】 通过对大棚茄子滴灌条件下室内外气温、地温、蒸发量和土壤含水量等进行的试验研究取得的大量现场观测数据分析,结果表明,大棚不仅具有良好的保温效果,能保证作物在冬季的正常生长;而且大棚外日平均气温累计值与作物需水量存在良好的关系,可作为指导大棚滴灌的依据。更多还原

【Abstract】 Based on analysis of a large amount of data gained from the observation of experiment of eggplant with drip irrigation in greenhouse,the water requirement of drip irrigation for eggplant in greenhouse is studied.Several factors such as the inside and outside temperatures of the greenhouse,the ground temperature,evaporation and soil water content are studied in detail.The result indicates that greenhouse has the good effect of heat preservation,which can guarantee normal growth of crops in winter,and the daily accumulated temperature on average outside the greenhouse has a good relation with the water requirement of the crop,which can be regarded as the basis for drip irrigation in greenhouse.更多还原
