一九八○、一九八一两年我们曾对F_(48)作了不同浓度、药效持久力、耐雨水冲刷力、阳光对药效的影响等试验研究,得出初步结论,发表在一九八二年《福建农业科技》第4期.一九八二年为了澄清某些水稻品种在抽穗至扬花期使用F_(48)后所产生的过敏反应会不会影响水稻产量?并对此药在多点大面积施用中的药效、秧田防病效果和药剂的稳定性能等问题,进一步进行试验.现将结果续报如下:
In 1980 and 1982, we conducted a pilot study on the effects of different concentrations of F_ (48), persistence of efficacy, scouring resistance to rain and the effects of sunshine on the pharmacodynamics. The preliminary conclusions were published in Fujian Agricultural Science and Technology, No. 4, 1982. In order to clarify whether the allergic reaction caused by using F_ (48) from heading to flowering stage in some rice varieties will affect rice yield in 1982, The drug in a large number of large-scale application of the efficacy of seedling disease prevention and stability of pharmaceutical properties and other issues, further testing now report the results as follows:
