稀土壳聚糖螯合盐对水产颗粒饲料性能的影响

研究了在饲料中添加稀土壳聚糖螯合盐（ＲＥＣＣ）对水产颗粒饲料性能的影响。根据鲫（Ｃａｒａｓｓｉｕｓａｕｒａｔｕｓ）鱼苗的营养需求配制４种类型的ＲＥＣＣ试验日粮,即１号饲料（０．００％）、２号饲料（０．０８％）、３号饲料（０．１６％）和４号饲料（０２４％）。测定４种饲料的粉化率和溶失率。结果显示,添加稀土壳聚糖螯合盐后可以降低饲料的 粉化率,饲料中添加０．１６％的稀土壳聚糖螯合盐效果尤其明显（Ｐ＜０．０１）;在饲料中添加ＲＥＣＣ可以显著降低饲料的溶失率（Ｐ＜０．０５）,并可以提高和改善水产颗粒饲料的性能。

Assessment of tillage erosion rates on steepland Oxisols in the humid tropics using granite rocks

Soil translocation by tillage may be an important factor in land degradation in the humid tropics. The objective of this study was to evaluate tillage-induced soil translocation on an Oxisol with 25% and 36% slopes in Claveria, Philippines for three tillage systems: contour moldboard plowing (CMP), moldboard plowing up and downslope (UMP), and contour ridge tillage (CRT). Small rocks 3–4 cm in “diameter” were used as soil movement detection units (SMDU). The SMDUs were placed at 10 cm intervals in a narrow 5-cm-deep trench near the upper boundary of each plot, the position of each rock recorded, and the trench backfilled. Five tillage operations used to produce one corn crop were performed during a one month period: two moldboard plowing operations for land preparation (except for CRT), one moldboard plowing for corn planting, and two inter-culture (inter-row cultivation) operations. After these operations, over 95% of the SMDU were recovered manually and their exact locations recorded. Mean annual soil flux for the 25% slope was 365 and 306 kg m⁻¹ y⁻¹ for UMP and CMP, respectively. For the 36% slope, comparable values were 481 and 478 kg m⁻¹ y⁻¹. Estimated tillage erosion rates for the 25% slope were 456 and 382 Mg ha⁻¹ y⁻¹ for UMP and CMP, respectively, and increased to 601 and 598 Mg ha⁻¹ y⁻¹, respectively, for the 36% slope. The mean displacement distance, mean annual soil flux, and mean annual tillage-induced soil loss for both slopes were reduced by approximately 70% using CRT compared to CMP and UMP.
