灌水上下限对日光温室薄皮甜瓜生长和产量以及水分利用效率的影响
Effects of Upper and Lower Limits of Irrigation on the Growth,Yield,and Water Use Efficiency of Muskmelon in Greenhouse
摘要
Abstract
Studying the effects of upper and lower limits of irrigation(soil moisture content as the lowest and highest proportion of field water holding capacity(FC))on the growth,yield,and water use efficiency(WUE)of muskmelon in greenhouses can provide a reasonable drip irrigation plan for muskmelon in greenhouse.Using the grafted seedlings of muskmelon variety Lvbaoshi Emerald 2(with the rootstock as a specialized pumpkin)as the test material,different water supply methods were applied during the flowering fruiting stage,fruit swelling stage,and fruit ripening stage based on a lower limit of 85％FC and an upper limit of 100％FC during the seedling stage.The upper and lower limits of water supply were set at 55％FC-70％FC(T1),70％FC-85％FC(T2),and 85％FC-100％FC(T3),respectively.The same water supply method was used to treat the musk melon at three growth stages,and the upper and lower limits of water supply were consistent.The effects of different water supply methods on the growth,yield,and water use efficiency(WUE)of the musk melon were analyzed.The results showed that the upper and lower limits of irrigation had an impact on the plant height,leaf area index,fruit traits,yield,and WUE of muskmelon in greenhouse.Among them,the agronomic traits of T2 treatment were co-ordinated,with the highest yield(26 999.95 kg/hm2)and WUE[131.22 kg/(mm·hm2)].The recommend-ed irrigation index for drip irrigation of muskmelon in greenhouse is 85％FC to 100％FC for irrigation during the seedling stage,and 70％FC to 85％FC for irrigation during the flowering and fruiting stage,fruit swelling stage,and fruit ripening stage.关键词
