| 摘 要： | 以6a生"金寿"杏为试材,通过4个氮、磷、钾肥配比田间试验:CK(N∶P2O5∶K2O=0∶0∶0)、处理A(N∶P2O5∶K2O=2∶1∶3)、处理B(N∶P2O5∶K2O=2∶2∶3)和处理C(N∶P2O5∶K2O=1∶1∶3),研究其对土壤养分含量、单果重、果实产量和品质的影响。结果表明:施肥可以提高100cm土壤养分含量、单果重和果实产量。在"金寿"杏收获后,A、B和C处理的100cm土层速效钾平均含量分别比CK处理提高了40.16%、37.59%和56.42%;可溶性固形物含量分别比CK提高了4.26%、6.65%和7.17%;单株产量也比CK分别提高了16.72%、28.46%和18.75%;B处理下单果重、单株产量及折合产量均为最高。综合经济效益,处理B(N∶P2O5∶K2O=2∶2∶3)的效果最佳。

| 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. |
