土壤水分调控对酥梨品质的影响

The Impact of The Soil Moisture control On Pear

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:不同处理间以塑料薄膜覆盖处理效果最好,不但果个较大,果实的固酸比值和产量也较高;树盘覆草次之,且具有土壤水分变化幅度较小和省工、省时等优点。

Using 45 - year peer trees as the tester, We analyze and mensurate the effect of different managing measures such as plastic film covered,grass covered,herbiferous naturally,irrigation termly and monoculture and so on on soil moisture and peers＇ quality, The results show that the plastic film covered measure is the best, by this means, the fruit is big, and the ratio of the connatural acid and the output are also high; grass covered measure is take second place, and this means has the advantage of small variational range of the soil moistures ,laborsaving and timesaving.
