沼肥对早熟蜜柑土壤肥力及产量品质的影响

1999-2004年间在早熟蜜柑上进行施用沼肥、猎粪等有机肥试验，结果表明，施用沼肥可显著提高土壤有机质、全氮、碱解氮的含量及土壤酶活性；可提高早熟蜜柑叶片叶绿素含量，持续稳定提高早熟蜜柑的产量，改善果实品质，以每公顷施用沼渣112500kg和沼液的处理效果最佳。

Effect of marsh manure on soil fertility , yield and quality of fruit in early mature orange

The trait of fertilization with marsh manure and hog manure was conducted in early mature orange orchard in 1999-2004. The results showed that the use of marsh manure could obviously raise the contents of orrganic materials, total nitrogen, alkaline hydrolysis nitrogen in soil, increase chlorophyll content and the activity of soil enzyme, stably promote the yield of the orange, and improve the quality of the fruits. The fertilization with 112.5t/hm^2 of marsh manure and slurry could get the best result.
