Soil fertility was raised because of planting mulch grasses and interplanting green manure on red soil young fruit tree orchard In the soil between rows of the orchard, soil organic matter, humus, huli acid content were much more increased, nitrogen & phosphorus nutrient of the soil was better conserved and available pottassium content was raised on interplanting green manure treatment In soil under canopy,oranic matter humus and huli acid content was obviously raised because of planting mulch grassed on the orchard, and nitrogen element nutrient was better conserved because of planting green manure on the orchard Meanwhile,exchanged calcium,mangnecium,free iron content,pH value on the soil between rows and under canopy,have been increased in varying degree,and the whole phosphorus, available phosphorus,potassium on the soil under canopy have been raised in varying level

果园生草、套种绿肥提高了红壤幼龄果园土壤肥力。在行间土壤,果园生草和套种绿肥可较大幅度地提高土壤有机质、腐殖质、富里酸含量,套种绿肥还较好保持了土壤N、P素营养,提高了土壤速效K含量;在冠下土壤,果园生草的土壤有机质、腐殖质、富里酸含量也有明显的提高,套种绿肥还较好保持土壤N素营养。此外,与试验前相比,行间和冠下土壤的交换性Ca、Mg,游离Fe2O3含量和pH值及冠下土壤的全P,速效P、K含量都有不同程度的提高。
