摘要: 以草莓丰香为材料,探讨三种灌溉方式(沟灌、滴灌、滴灌+半基质)对粘性土壤条件下草莓产量、光合生理指标和根系生长的影响。结果表明:与沟灌相比,滴灌+半基质方式和滴灌方式均能促进草莓的生长和增加其产量,单株产量分别增加36.89%和29.30%,在开花期草莓叶片光合速率提高了41.56%和34.46%;在结果期,水分利用率提高了28.69%和24.65%,根冠比提高了51.78%和29.28%;滴灌+半基质方式和滴灌方式更有利于根系生长,在开花期根体积提高了164.25%和78.72%、根鲜重提高了117.18%和84.07%、在结果期根系活力提高了70.98%和48.38%;滴灌+半基质栽培灌溉方式是一种适宜粘性土壤草莓的灌溉方式。

Abstract: With strawberry Fragaria×ananassa Duch cv. Toyonoka as experimental materials, the paper preliminarily studied the effects of three different irrigation patterns, (furrow irrigation, drip irrigation and half-substrate drip irrigation), on the yield, photosynthetic physiological indexes and the root growth of strawberry. The results showed that compared with furrow irrigation, the yield and growth increased with the half-substrate drip irrigation, and yield per plant increased 36.89% and 29.30% and the photosynthetic rate in blooming stage increased 41.56% and 34.46%; The WUE increased 28.69% and 24.65% in fruiting stage, and the root cap ratio increased 51.78% and 29.28%. The pattern of half-substrate drip irrigation and drip irrigation is more conductive than the furrow irrigation on root growth, the root volume increased 164.25% and 78.72% in blooming stage, and the root fresh weight increased 117.18% and 84.07%, and the root activity increased 70.98% and 48.38%.The half-substrate drip irrigation was an appropriate pattern for strawberry culture under clay soils.
