摘要
采用田间试验对比法,进行了保水生物复合肥对丁香和樟子松苗木生长影响的研究,结果表明:(1)土壤含水量:丁香试验区处理比对照提高6.7%,樟子松试验区处理比对照提高0.81%;(2)土壤微生物总数(×106个/g干土):两树种试验区施肥处理分别是对照的319.9%和20.6%;(3)土壤的碱解氮、速效磷和速效钾含量(mg/kg):丁香试验区施肥处理分别比对照提高48%、52.9%和44.3%,樟子松试验区分别提高61.9%、35.3%和35.2%;(4)丁香苗木地径和苗高施肥处理比对照分别提高135%和94.8%,樟子松苗木地径和苗高分别提高97.7%和44.2%。
The influence of water - holding biological compound fertilizer on growth of seedlings of Syzygium aromaticum and Pinus sylvestris var. mongolica has been studied by use of field test contrast method, the results show： （1） In experimental plot of Syzygium aromaticum, the soil water content of treatment is raised by 6. 7% than CK; in experimental plot of Pinus sylvestris var. mongolica, the soil water content of treatment is raised by 0. 81% than CK. （2） The total number of microbo after fertilizer treatment in two experimental plots are 319. 9% and 20. 6% higher than CK separately. （3） In experimental plot of Syzygium aromaticum, the content of available nitrogen, available P and available K is 48%, 52.9% and 44.3% higher than CK separately; in experimental plot of Pinus sylvestris var. mongolica, the content of available nitrogen, available P and available K is 61.9%, 35.3% and 35.2% higher than CK separately. （4） After fertilizer treatment, the ground diameter and height of seedlings of Syzygium aromaticum are raised by 135% and 94. 8% than CK separately, and the ground diameter and height of seedlings of Pinus sylvestris var. mongolica are raised by 97.7% and 44. 2% than CK separately.
