| 摘 要： | 本文论述了三种肥料结构对红壤性水稻土氮磷钾养分状况的影响。土壤中的生物学有效性氮、氨基酸态氮、氨基酸、速效磷和活性有机磷的含量变化趋势是,以作物残体+灶灰+猪粪+化肥处理>作物残体+灶灰+化肥处理>绿肥+化肥处理。在各处理中,土壤中速效钾和缓效钾的含量变化不大,但采取秸杆、灶灰、菜籽饼和猪粪还田的措施,在节约化学钾肥提高作物产量中起了良好作用。

| Abstract: | The influence of three fertilizer structures on the status of nitrogen,phosphorus and potassium in paddy soil derived from red earth was studied. Thecontents of bio-available N, amino acid N, amino acid, quick-acting phosphorus andlabile organic phosphorus in soils vary with fertilizer structures. The trend of thevariation is as follows: treatment of crop remainder+kitchen ash+pig manure+chemical fertilizer>treatment of crop remainder+kitchen ash+chemicalfertilizer>treatment of green manure+chemical fertilizer. The contents of guick-acting potassium and slow-available potassium in soils do not vary obviously in eachtreatment, but the application of straws, kitchen ash,rape seed cake and pigmanure to soils plays a good role in increasing the output of crop and in sayingChemical potassium fertilizers. |
