Abstract:
Taking 2-year-old ‘Fuji’ apple trees (Malus pumila Mill) as test material，the effect of different ground cover teratments(polypropylene film mulching,plastic film mulching,straw mulching,cleaning tillage) on soil moisture content and bulk density of the orchard soil，dry weight of per hundred leaves，average content of chlorophyll and photosynthetic rate (Pn) was studied.The results showed that the mass soil moisture content of mulching managements was significantly higher compared with the cleaning tillage.The order was polypropylene film mulching>plastic film mulching>straw mulching>the cleaning tillage.Three different mulching treatments all had the obviously effect on reduce the soil bulk density and the method of straw mulching gave the best result.Ground cover treatments could greatly increase the dry weight of per hundred leaves，while straw mulching and polypropylene film mulching could signally improve the total chlorophyll content.Compared with the double peak curve which were observed on the diurnal changes of Pn for cleaning tillage treatment，the polypropylene film mulching，straw mulching and plastic film showed single peak curve.In conclude,the results indicated that different mulching managements could improve both soil and apple tree characteristics,among which polypropylene film mulching was the most efficient.
