Effects of Ground Cloth Mulching on Soil Water, Temperature,Yield and Quality in Apple Orchard in Weibei Plateau
The experiments were conducted to study the influences of different mulching patterns (including ground cloth mulching and plastic film mulching) on soil moisture,soil temperature,leaf photosynthesis,yield and quality in apple orchard in Weibei Plateau of Shaanxi province.The results indicated that ground cloth mulching significantly increased soil moisture content.Ground cloth and plastic film mulching saved water 35.1 mm and 28.9 mm respectively compared with the control during the reproductive period.Ground cloth and plastic film mulching improved the average soil temperature of 0～25 cm soil layer under ground cloth and plastic film mulching treatments increased by 2.8 ℃ and 4.5 ℃ compared with the control in spring while they increased by-0.3 ℃ and 4.1 ℃ in summer.The ground cloth and plastic mulching increased yield by 32％ and 20.4％ respectively compared with the control.The ground cloth mulching simultaneously improved fruit trees net photosynthesis rate,stomata conductance,soluble solids content,intercellular CO2 concentration,the soluble solid content,fruit brightness and red degree of degree,but reduced the fruit acidity.
