酥梨果实发育期土壤水分调控方法及其对果实品质的影响

以45年生酥梨树为试材,分析测定塑料薄膜覆盖、树盘覆草、自然生草、定期灌水、清耕等不同土壤水分管理措施对土壤水分和酥梨品质的影响,结果表明：塑料薄膜覆盖和树盘覆草处理中,土壤含水率比较适宜,且变幅较小,有利于果实生长发育和提早着色,提早成熟,产量和品质较好;其它处理中土壤含水率要么过高,要么过低,且变幅较大,酥梨的果实品质也比较差.因此,在黄河故道区无公害酥梨生产中,建议采取塑料薄膜覆盖和树盘覆草方法,此方法操作简单,便于实施.

Influence of Regulation and Control methods of Soil Moisture on Quality of Fruit in Non-public Nuisance Crisp Pear Garden in Area of Old Course of Yellow River

The experiment was conducted to determine the influence of different regulation and control methods of soil moisture, such as plastic film mulching, covering grass under trees, growing grass under trees, irrigating regularly, loosening the soil under trees, on quality of fruit in a non-public nuisance crisp pear garden in the area of Old Course of Yellow River. The results showed that the soil moisture was moderate for the tree growth by plastic film mulching and covering grass under trees, which had led to higher yield and quality of the fruit than that of other treatments.
