摘要
研究了施用产自湖北高硒区的富硒复混肥、硒矿粉对鄂杂棉10号主要农艺性状和产量的影响。结果表明,硒矿肥能够提早棉花吐絮期,改善棉花营养状况,促进棉铃发育,降低脱落率0.68~3.78个百分点,对增加早期棉花产量有显著效果;含量为1 000 mg/kg的硒矿粉在吐絮、棉铃发育、降低脱落率、早期产量上优于含硒量为250 mg/kg和550 mg/kg的富硒复混肥。
Effects of Selenium ore fertilizer on main agronomic traits and production of Ezamian No.lO were investigated. The results showed that selenium mineral fertilizer could make the opening stage of cotton,improve nutritional status of cotton ,pro- mote the development of cotton bolls,decrease expulsion rate 0.68%~3.78%,increase significantly the effeet of cotton produc- tion at the early time. Selenium ore powder which the content of Se was 1 000 mg/kg,in deereasing expulsion rate, the cotton yield at the early time was better than complex fertilizer rich Selenium which the content of Se were 250 mg/kg and 550 mg/kg.
