| 摘 要： | 1990年4—11月,在湖南祁阳中国农科院红壤实验站布置田间试验,比较含SO_4~(2-)和Cl~ -类肥料对作物生长的效应。结果表明,SO_4~(2-)促进早稻和晚稻营养生长,但水稻收获时的稻谷产量以Cl~-肥料处理区较高。两种阴离子对水稻养分吸收无显著差异,但SO_4~(2-)对早稻体内的磷素转化不利,可能是稻谷产量较低的原因之一。

| Abstract: | In this article, effects of SO_4~(2-) and CI~- fertilizer applications on rice growth were studied at the Red Soil Experimental Station, CAAS, in Qiyang county, Hunan province. Results showed that vegetative growth of rice both in the early and the late season was improved by SO~4~(2-) fertilizer, while reproductive growth and grain yields of the crops were increased by CI~- fertilizer. There were no signifieant differences between the two treatments in their nutrient absorption, but phosphorus transition in plant of the early rice was indeed restrained by the treatment of SO_4~(2-) fertilizer application. |
