摘  要：
针对目前敌磺钠在单季茭白上应用的不规范,研究了敌磺钠的不同使用时期、浓度和次数对单季茭白产量和产值的影响。结果表明:在单季茭白一年收二茬种植地区,敌磺钠能显著促进茭白结茭,茭白采收期提早50 d左右。在茭白移栽150,160和175 d各喷施一次浓度为0.5 g·L-1(有效成分)的敌磺钠即能促进茭白结茭,提高产量。在纯单季茭白种植地区,喷施1次敌磺钠可明显提早茭白采收期,同时提高茭白产量和产值,但随着使用次数的增多,茭白产量和产值明显下降。建议最多使用1次浓度为1 g·L-1(有效成分)的敌磺钠,在茭白移栽后40~60 d使用效果较佳。

摘  要：
In view of the non-standard usage of fenaminosulf on single-harvesting Z. latifolia,the effects of different spraying periods,different concentrations and spraying times on yield and value of single-harvesting Z. latifolia were studied. The results show that in some regions where single-harvesting Z. latifolia could be harvested twice per year,fenaminosulf could significantly promote forming swollen gall,advance the harvest time for about 50 d. Fenaminosulf with 0. 5 g·L- 1( a. i.) should be used at 150,160 and 175 d after transplanting of Z. latifolia last year. In normal single-harvesting Z. latifolia growing regions,once application of fenaminosulf could obviously advance harvest time and improve yield and benefit,but with more frequency of use,yield and benefit of Z. latifolia decreased more significantly. In conclusion,fenaminosulf with 1. 0 g·L- 1( a. i.) should be used only once at 40-60 d after transplanting of Z. latifolia.
