施肥对杨树人工林土壤养分及环境影响的研究

Abstract

Abstract:

This paper deal with the effect of fertilization for 4 years on the changes of the soil nutrients, the soil water-physical characters and the soil microbes in the poplar plantation. The result showed that in the best treatment(100 kg N/hm²+100kg P₂O₅/hm²) of fertilization the content of organic matter, total N, rapidly available N in the soil, was increased by 21%, 60% and 14% respectively compared with control. But there was little effect on the total P, rapidly available P and physical-water characters in the forestland. The analysis of soll microbes showed that fertilization could increase 37.7% of the total amount of the soil microbes than that before plantation, thus strengthen the activities of soil biochemistry, and promote the forest grew up better. The severe influence on the physical-chemical properties of soil and the eco-logical environment can not result from a suitable fertilization.

Key words: Fertilization, Affect, Soil nutrient, Soil environment
