| 摘 要： | 本文重点讨论了水稻旱种土壤养分问题.主要阐明:水稻旱种与淹水种植土壤养分的区别、水稻体内三要素的变化、氮素利用状况以及水稻体内养分运转率的区别等.同时提出,水稻旱种与淹水种稻在氮素营养的来源方面差异较大.淹水种稻应增施有机肥料,培肥土壤,而水稻旱种应适当增施一些无机氮肥.

| Abstract: | The problems of some nutritions in soil were studied by microplots methods with labelled nitrogen during cultivatoin of unwaterlogged rice. This paper illustrates mainly following aspects: The general differences of some nutritions in soils between waterlogged and unwaterlogged cultivation of rice, the transformatoins of nitrogen, phosphorous and potash turned in rice, the efifciency of transformation of nutritins and the utilization of nitrogen. Results showed that it seems a lot of differences in utilized nitrogen sources between waterlogged and unwaterlogged rice. It is suggested that m0re manure should be applied ia waterlogged soil, whereas m0re fertilizer should be applied in unwaterlogged soil. |
