Soil fertility in a Phyllostachys pubescens forest of southern Sichuan

    Corresponding author: JIANG Jun-ming

Abstract: Growing altitude and bamboo growth history were used to analyze the status and the evolution of soil fertility according to four aspects,namely 1) water-holding capacity,2) soil acidification in four Phyllostachys pubescens bamboo stands (on a valley bottom,middle slope,upside slope and a valley top) of southern Sichuan,and nutrient status,and profile characteristics of soil. Results showed that 1) soil structure in the rhizosphere was very high;water-holding capacity and organism count in the soil increased with altitude and duration of bamboo growth. However,soil etiolation and soil acidification was obvious. 2) Soil acidity was adjusted with lime;best applications were 10.625 t·hm-2 on the valley bottom,14.811 t·hm-2 for the middle slope,and 12.558 t·hm-2 on the valley top. 3) In all the soils,N for attaining high yield was insufficient;K was insufficient or very insufficient;and P was extremely insufficient. Therefore,at present,N and P fertilization is the best way to increase yield of Phyllostachys pubescens bamboo stands in southern Sichuan.[Ch,3 tab. 22 ref.]
