Abstract:

By comparing the soil analysis data of 2002 and 2009 gathered from two main types of soils on the two fixed-location soil fertility monitoring sites under the condition of bamboo shoot(CV. Ventricousinternode) planting, the results showed that eight years later, pH values of two plough-layer soils fell respectively from 4.74 and 5.14 to 3.39 from 29.60 g/kg and 26.96 g/kg to 50.67g/kg and 42.84 g/kg; total N from 1.70 g/kg and 2.16 g/kg to 2.98 g/kg and 2.59 g/kg; total P from 0.76 g/kg and 0.94 g/kg to 1.27 g/kg and 1.44 g/kg; total K from 29.10 g/kg and 32.40 g/kg to 33.40 g/kg and 38.70g/kg. Moreover, an increase at a different extent was observed when comparisons were made in the contents of soil available N, P and K, but a decrease in the contents of available B, Zn, Mn and Cu was found when comparisons were made. After the bamboo shoot growth for the lasting eight years, an increase in soil exchangeable H+ and Al3+, along with a decrease in the total amount of soil exchangeable Ca2+, Mg2+, K+ and Na+, has resulted in a fall in base-saturation percentage. As a conclusion, there was an increase in the content of soil macronutrients and in soil acidity but a fall in the content of soil micronutrients under the condition of consecutive bamboo shoot growth for years in Linan.
