Abstract:

The pattern of economic forest of double-terraced field with slope interval was studied systematically, including the measures of increasing soil moisture, fertilization and fruit yield.The results showed that soil moisture of double-terraced field with slope interval(main terrace) in growing season was 2.1 % higher than that of ternace without slope interval.The yield of dry grass in auxiliary terrace was 1kg/m², which can be used in burying fresh grass into soil of main terrace or covering the surface of the main terrace soil, so as to increase the soil nutrient contents of the main terrace.The kernel yield of 5 -year-old individual apricot tree with sweet kernel increased 69.4 % compared with terrace without slope interval.And there was significant difference in tree growth between terrace with and without slope interval.

Key words: The calcareous rock area of Taihang mountain, Double-terraced field with slope interval, Economic fo rest in mountain land, Apricot tree with sweet kernel
