摘要: 通过分枝期和初花期对大豆喷施烯效唑试验,研究了施药时期和施药浓度对大豆产量和品质的影响。结果表明,经烯效唑处理的大豆植株表现为株高降低,茎粗增粗,分枝数增多,产量增加;蛋白质含量、蛋白质产量和粗脂肪产量均高于对照(除A2B1),均以分枝期喷施75mg/kg烯效唑最高,分别比对照提高5.05%,56.59%和59.15%。可见,分枝期喷施75mg/kg的烯效唑最有利于产量形成,蛋白质和粗脂肪的积累。

Abstract: Differences of soybean yield and quality between treatments was studied by spraying different concentrations of uniconazole at the V5 and R1 stages. Spraying 25-100 mg/L uniconazole reduced plant height, enhanced stem diameter, and increased branch number and yield. The protein content, protein yield, and fat yield of all treatments were higher than those of the control (except A2B1). They were highest in the 75 mg/kg uniconazole treatment at the V5 stage where they higher than the controls by 5.05%, 56.59%, and 59.15%, respectively. Spraying 75 mg/L uniconazole at the V5 stage mainly increased yield, protein, and fat accumulation.
