心连心加锌尿素对苗期玉米的促生效果

Growth-promoting effects of Xinlianxin zinic-supplemented urea on corn plants at seedling stage

锌是动植物生长发育所必需的一种微量营养元素,玉米对锌尤为敏感.心连心加锌尿素(XZU)是一种新型尿素产品,除了氮元素外还含有锌元素和植物源促生因子.本研究就XZU对苗期玉米的促生效果进行测试.研究结果表明:与传统尿素相比,经XZU处理的玉米幼苗的株高、根长、地上部分与根系干重及叶绿素含量显著增加.

Zinc is one of the necessary microelements for developments of animals and plants. Corn plants are especially sensitive to zinic. The Xinlianxin zinic-supplemented urea（ XZU） is a new type of urea product containing zinc and botanical growth-promoting factor as well as nitrogen. In the present work,the growth-promoting effects of XZU on corn seedlings were tested. The results showed that the XZU-treated corn plants had significantly enhanced plant heights,root lengths,dry weights of aboveground parts and roots as well as chlorophyll contents compared to those treated by the traditional urea.
