Effect of Rhizosphere Ventilation Volume on Plant Growth,Transpiration and Fruit Yield of Potted Tomato

, 2011
为确定作物生长的最优根际通气量,采用空气压缩机控制供气,设置了0.4(T1)、0.8(T2)和1.2(T3)3个通气系数,研究根际通气量对盆栽番茄生长、蒸腾量及相关生理指标的影响。结果表明:通气处理可显著提高番茄植株的茎粗、叶面积指数、叶片叶绿素含量及干物质积累,且均在T2处理下达最高值;在试验不同时期,盆栽番茄的累积蒸腾量受通气量影响的表现不同,盆栽番茄的累积蒸腾量最终表现为:T2>T3>T1>CK;通气处理对盆栽番茄的产量和作物水分生产率均有显著影响。在T2处理下的产量 ...

Effects of Water Stress on Physiological Characteristic and Water Production Efficiency of Tomato

, 2008
根据番茄的生长发育特点,分别以50%、60%、75%田间持水量作为苗期、开花坐果期、结果期的土壤水分下限,每个生育期的土壤水分上限设置3个水分水平,研究不同生育期水分亏缺和亏缺程度对番茄生长发育及生理特性的影响。结果表明,不同生育期的水分亏缺对番茄株高、茎粗、叶绿素相对含量、日光合及蒸腾速率变化等均有不同程度的影响,呈现明显的生长与生理补偿效应,水分胁迫处理的日光合速率峰值提前出现,蒸腾速率随水分亏缺程度的增加而减少,这有助于调控番茄无用的蒸腾耗水。通过对番茄不同生育期的灌水量和产量关系的研究得出 ...

番茄滴灌在日光温室内耗水规律的初步研究

, 2000
:对山东禹城地区采用滴灌灌溉的番茄 ,在日光温室内 1-4月份生长的耗水规律及空气温度、空气湿度和地温等环境因素进行了初步的研究。结果表明 ,在严冬季节不用加温条件下 ,日光温室内的平均温度可维持在18℃左右 ,内外温差达 2 0℃左右 ,可基本满足番茄生长发育的需求。将滴灌带下 15cm处的土壤水势维持在番茄生长的适宜范围 (≥ -2 0kPa) ,日光温室内的水面蒸发量与作物的需水量和灌溉水量存在很好的一致关系 ,因此 ...
