Abstract

Abstract: Observations in 1982—1983 show that in Huitong, a productive centre of Cunninghamia lanceolata, within the 22 years old artificial Cunninghamia lanceolata forest which is located in south west slope of 15 degrees, the total radiation heat in the upper part of crown canopy is 78,388 cal/cm²·yr., reflecting heat is 6,848 cal/cm²·yr., transmission heat is 8,648 cal/cm²·yr., and absorption heat is 62,892 cal/cm²·yr.

Key words: Rice/wheat rotation, No-tillage, Organic manure, Soil fertility
