Abstract:
With 6-year old ‘Jinshou’ apricot trees as test materials，designed four different N,P,K fertilizer application methods：CK(N∶P2O5∶K2O=0∶0∶0),A(N∶P2O5∶K2O=2∶1∶3)，B(N∶P2O5∶K2O=2∶2∶3)，C(N∶P2O5∶K2O=1∶1∶3).The effects of these treatments on the soil nutrients，fruit weight，yield and quality of apricot were studied.The results showed that fertilization could increase the 100 cm depth of soil nutrient concentration within 100 cm in depth and fruit weight and fruit yield.After harvest of ‘Jinshou’ apricot.Compared with CK，A,B,C treatment could increase 100 cm depth of the available K content by 40.16%,37.59.% and 56.42%，respectively，and could increase soluble solid content by 40.16%,37.59.% and 56.42%，respectively compared with CK，and also increased fruit weight by 16.72%，28.46% and 18.75%，respectively.Treatment B had the best effect in the fruit weight，yield of per plant and yield.Therefore，treatment B(N∶P2O5∶K2O=2∶2∶3) was the optimum fertilizing method for apricot tree.
