摘　　要：以栽培4~6 a的漾濞泡核桃幼树为试材,选用有机肥、腐熟的农家肥和史丹利复混肥,在秋季对不同立地条件的2个核桃园进行对比试验,一年期间生长量调查结果表明:有机肥和农家肥分别与史丹利复混肥配施、采取覆盖和不覆盖的处理对2个试点核桃幼树冠幅生长的影响不大;但对2个试验点核桃幼树地径生长的影响差异显著。即试点一:10 kg有机肥和2 kg史丹利复混肥料配施后,覆盖处理其地径生长量最大,年均生长量为0.72 cm;试点二:10 kg农家肥和2 kg史丹利复混肥料配施后,不覆盖处理促进地径和冠幅的生长效果优于有机肥,年均生长量分别为1.49 cm和126.17 cm,冠幅比覆盖的高5.34 cm。By combing the organic fertilizer and the farmyard manure with Stanley compound fertilizer respectively,the Juglans sigillata trees of 4-6 years old were used as the test material to compare the two walnut gardens with different site conditions in autumn.The results of the annual growth survey showed that organic fertilizer and mulching factors had little effect on the crown growth,but had significant difference on the ground diameter growth of the two experimental sites.Specifically,one experiment showed that with the combination of 10 kg organic fertilizer and 2 kg Stanley compound fertilizer,the mulching treatment led to the maximum growth of ground diameter,which was 0.72 cm,while the other experiment showed that with the combination of 10 kg farmyard manure and 2 kg Stanley compound fertilizer,and with the no-mulching treatment,the growth effect of the ground diameter and the crown width was better than that of the organic fertilizer,with an average annual growth of 1.49 cm and 126.17 cm respectively,and the crown width was 5.34 cm higher than that of mulching.
