摘  要:
以6年生的晚秋黄梨为试验材料,从初花期开始,每隔15d分别喷施300倍、500倍和600倍的氨基酸硒叶面肥,直到果实成熟前15d停止.试验结果表明,氨基酸硒叶面肥可以极显著地提高梨果实中硒元素的含量,提高果实中钾、钙等矿物质元素的含量,从而生产出符合"富硒食品硒含量分类标准"的富硒梨.同时,氨基酸硒叶面肥还可以增加梨单果重和可溶性固形物的含量.氨基酸硒叶面肥对叶片也有积极的作用,能增加叶面积和叶绿素含量.实验得出,300倍氨基酸硒叶面肥是生产富硒梨适宜的喷施浓度.

摘  要:
Taking six-year-old yellow pear tree in late autumn as the experimental material, from the beginning of flowering period until 15 days before fruit ripening, they were sprayed 300 times, 500 times and 600 times using foliar fertilizer of amino acid selenium every 15 days. The experimental results showed that foliar fertilizer of amino acid selenium could significantly increase the content of selenium and other mineral elements in pear fruit. It could produced selenium pear which meet the relevant classification standards. At the same time, foliar fertilizer of amino acid selenium could increase the content of average fruit weight and soluble solids of pear, so as to improve the quality of pear from purpose. Foliar fertilizer of amino acid selenium also had positive effect on leaf, increasing leaf area and chlorophyll content. Therefore, 300 times the concentration of selenium amino acid foliar fertilizer production was suitable selenium pear.
