| 摘 要： | 针对京郊温室草莓生产中使用滴灌而水肥利用率仍偏低的现状,以‘红颜’为试验材料,在草莓结果期采用相同频率、相同浓度的水肥混合液,设计4个不同的用量,研究草莓结果期的适宜水肥用量.结果表明,草莓结果期灌水总量97.9 m3/667 m2、施肥总量87.8 kg/667 m2的中量滴灌处理较好,比常规滴灌节约灌溉水23.7%、节约纯养分25.3%,增产13.4%,糖度增加1.1个百分点,水分生产效率提高2.4 kg/m3,水分生产效益提高47.2元/m3.建议草莓结果期11~次年3月每7~10 d滴灌1次,3~5月每3~5 d滴灌1次,每次灌水2.6~3.5 m3/667 m2,滴施水溶肥2.5~3.8 kg/667 m2为宜.

| Abstract: | Drip irrigation has been widely used in greenhouse strawberry production in Beijing suburb,but appropriate water and fertilizer quantity is not known,and water and fertilizer use efficiency is still low.With’Hongyan’as trial material,4 treatments of different quantity of water and fertilizer were used with the same irrigation frequency and the same concentration of fertilizer solution in strawberry fruit period.The results show that the middle irrigation treatment(with total water of 97.9 m3/667 m2 and total soluble fertilizer of 87.8 kg/667 m2)is better.Compared with traditional irrigation,it can save water and fertilizer by 23.7% and 25.3%,increase yield by 13.4%,increase water use efficiency by 2.4kg/m3.The suggestion of irrigation 2.6-3.5 m3/667 m2 every 7-10 days from December to March in next year and every 3-5 days from March to May,adding fertilizer 2.5-3.8 kg/667 m2 every time in strawberry fruit period is put forward. |
