The soil fertility in Heilongjiang Province has decreased and its physicalproperties become poorer as a result of frequent tillage since 1950s. The experimental results indicated that pig manure played an important role in soil fertility improvement. The water stability index and porosity of the aggregates increased, the bulk density decreased. The experimental results provided the theoretical base for reducing the times of tillage.

Study on the distribution of organic and inorganic cementing materials in different sizes of water stable aggregates in diameter of>5, 3—1, 1—0.5 and < 0.25mm separated from latosols, latosolic red earths and red earths by using a method of orderly sucessive removing the colloid from aggregates was carried out. Results show that with the increase in activity of clay particles and with the decrease in content of inorganic cementing material after exploitation of red soils the water stability of aggregates and the soil structural coefficient are decreased. These parameters, however, can be gradually increased in the application of organic material under the rational fertilization and management of soil. The relation of structural stability of red soils to soil zonality was also discussed. The strengthening structural stability of red earths in middle subtropics by application of organic material is more important than in tropical latosols.

本文应用顺序脱胶法,对砖红壤、赤红壤和红壤在不同利用方式下的水稳性团聚体的有机和无机胶结物组成进行了分析研究。水稳性团聚体共分>5,3—1,1—0.5和<0.25毫米四级。结果表明,红壤开垦后随着粘粒活度的增加和无机胶结物含量的降低,土壤团聚体的水稳性和土壤结构系数逐渐降低。但是,一旦采用合理的施肥和管理方法,这些物理参数又会逐步恢复和增加。此外,还研究了土壤结构稳定性与土壤地带性的关系。作者认为在中亚热带的红壤上施用有机物料以增强它的结构稳定性比热带砖红壤上施用更为重要。

The soil fertilities of three kinds of plantations were measured, those were pure 11-year Alniphyllum fortunei plantation, pure if-year Chinese fir plantation and if-year Chinese fir plantation mixed with Alniphyllum fortunei. The measures showed that the mixed forest has a better fertilizing ability than the others, its physical and chemical properties being superior to the others, the pure Alniphyllum fortunei plantation is the second. For this case, the Chinese fir plantation mixed withAlniphyllum fortunei...

The soil fertilities of three kinds of plantations were measured, those were pure 11-year Alniphyllum fortunei plantation, pure if-year Chinese fir plantation and if-year Chinese fir plantation mixed with Alniphyllum fortunei. The measures showed that the mixed forest has a better fertilizing ability than the others, its physical and chemical properties being superior to the others, the pure Alniphyllum fortunei plantation is the second. For this case, the Chinese fir plantation mixed withAlniphyllum fortunei is worth popularizing to plant in Fujian province.

对11年生拟赤杨纯林、拟赤杨杉木混交林和杉木纯林土壤肥力的研究结果表明:拟赤杨杉木1:3混交林具有良好的培肥土壤能力,同时土壤结构体破坏率、团聚体、水稳性团聚体、土壤结构系数、土壤孔隙度和通气度也表现最好;其次是拟赤杨纯林,最差是杉木纯林.可见拟赤杨杉木1:3混交林可在我省山区推广应用.
