摘  要：
对杉木林施用鸭粪的试验研究结果表明,施用鸭粪对林地土壤的理化性质有较好的改善作用,同时明显地促进杉木林的生长。在施肥后的3 a时间中,土壤的质地、结构得到改善,通透性能明显增强,土壤密度由施肥初期的平均1.20 g.cm-3减小到第3 a的1.13 g.cm-3,田间持水量从32.19%提高到42.41%,土壤孔隙度3 a内增加了6.84%,土壤有机质、全氮、水解氮、有效磷、速效钾等养分含量依次增加了9.08 g.kg-1、0.216 g.kg-1、20.48 mg.kg-1、5.18 mg.kg-1和37.39mg.kg-1,而pH值提高了0.63;3 a内林分年均胸径、树高、单株材积分别比对照增加了0.43 cm、0.30 m和0.007 4 m3。

摘  要：
Study on using duck-manure in Cunninghamia Lanceolata Stands and the results showed that using duck-manure can be good at improving soil physiochemical properties of woodland and the stands productivity are evidently increased.After three years of fertilization,both the texture and structure of the soil have been improved,soil aeration has been evidently boost up,soil density decreased from average 1.20 g·cm~-3 to 1.13 g·cm~-3,moisture capacity of field has been enhanced from 32.19% to 42.41%,the soil porosity increased 6.84%.The content of soil nutrients such as organic matter,total nitrogen,hydrolytic nitrogen validity phosphorus and quick effective potassium were respectively increased 9.08 g·kg~-1,0.216 g·kg~-1,20.48 mg·kg~-1,5.18 mg·kg~-1 and 37.39 mg·kg~-1 and pH value also increased 0.63.Comparing to antitheses,the average amount of growth per year of tree height,DBH and volume of wood were respectively increased 0.43 cm,0.3 m and 0.007 4 m~3 in three years.
