| 摘 要： | 为了解施用硒肥对小麦籽粒含硒量、小麦产量及经济效益的影响,探讨喷施不同亚硒酸钠溶液的施肥效果,在豫东潮土上进行了小麦喷施亚硒酸钠试验.结果表明,喷施亚硒酸钠对小麦产量、经济效益有显著的影响,喷施亚硒酸钠比对照喷清水可增产小麦1691.4～2443.2 kg/hm2,增产率13.6%～15.2%,每公顷净增收益2653.2～3820.8元.喷施亚硒酸钠溶液的处理小麦籽粒中硒的含量均比喷清水处理高,可提高硒含量0.07～0.14 μg/kg,提高幅度为124.1%～148.3%,其中喷亚硒酸钠溶液浓度达到15mg/kg时效果最好,表现为籽含硒量较高,增产幅度最大,净增经济收益最多.

| Abstract: | Abstract: Test of spraying NASEO3 on winter wheat was carried out on alluvial soil in east of Henan province,the results are as follows, sodium selenite could improve wheat yield signifcantly and has a significant economic impact, spraying NASEO3 can improve wheat yield 1691.4~2443.2kg?hm-2 compared with water spraying only,the improve rate is 13.6~15.2%,and can improve wheat se 0.07-0.14 Se?ugkg-1compared with water spraying only,the improve rate is 124.1-148.3% net income per hectare is 2653.2 yuan ~ 3820.8 yuan. |
