摘要：为探索一条实现柑橘皮渣无公害利用的好途径,2004—2005年在重庆市忠县的哈姆林甜橙幼树园碱性土上进行本试验。结果初步表明:(1)在皮渣压埋量相同情况下,土壤通气状况好则皮渣腐烂快。在通气性极差的板结土壤或积水的土壤中,皮渣腐烂极慢。(2)浅埋的皮渣量越大,生长量越小;浅埋量110kg/株时,当年生长量显著减小。皮渣深埋(45～50cm),对促进树高和树冠生长作用显著。(3)土壤pH值的降低幅度与皮渣的压埋量成正相关,并且压埋浅,pH值降幅大。

Abstract: We developed the experiment on Hamlin citrus orchard of Zhongxian,Chongqing with alkaline soiland during 2004 to 2005, in order to use citrus pericarp without pollution. The results showed as following aspects. Firstly,the pericarp rot rapidly in soil with good aeration but very slowly in harden soil with bad aeration after same amount of pericarp buried. Secondly,trees grew less with increasing amount of buried pericarp,and significantly reduced after buried 110 kg pericarp per plant . Deep-burying 45～50 cm can promote the growth of height and crown spreading. Thirdly,Reduction of soil pH had a positive correlation with amount of pericarp,and the shallower buried,the more pH value decreased.
