日光温室青花菜耗水规律及水分利用效率的研究
|
摘要
在膜下滴灌条件下,研究了温室秋茬青花菜不同生育阶段控制水分对耗水规律、水分利用效率以及产量的影响。结果表明,青花菜全生育期内耗水量、耗水强度均表现为苗期﹥莲座期>结球期的规律;水分生产函数的敏感指数为结球期﹥苗期﹥莲座期,因此青花菜节水宜在莲座期进行,结球期应保证水分供应充足,避免减产;苗期和莲座期分别控制灌水量为常规灌水量65%的处理,产量高、水分利用效率较高,是青花菜适宜的灌溉量。
Under the drip irrigation condition,the influence of controlling irrigation amount in different growth stages on water consumption,water utilization efficiency and yields of greenhouse brassica is carried out.The results show that the rank for the amount and intensity of water consumption during the whole growth period from larger to less is seedling stage,rosette stage,and heading stage;the rank for water sensitivity indices of water production function is heading stage,seedling stage,and rosette stage;thus water-saving irrigation should be carried out during rosette stage to avoid the reduction of output and moisture should be supplied adequately during heading stage.The treats,in which the irrigation amount is controlled to be 65% of normal irrigation amount,has higher yields and water utilization efficiency,and its irrigation amount is suitable for brassica.
