蓝革屑水解液螯合肥对水培青稞苗期生长的影响

Effect of Chelate Fertilizer of Wet Blue Shaving Hydrolysate on the Growth of Highland Barley Seedling in Hydroponics

通过水培实验研究了蓝革屑水解液螯合肥对青稞苗期生长的影响。观察水培7 d和14 d的青稞苗生长状态,结果表明青稞苗的高度、茎部粗壮程度以及叶宽均优于对照组,在实验所用的浓度范围内,水培液的浓度越高,效果越显著。收苗后的测试结果显示,实验组青稞苗的平均高度、茎粗、叶宽、湿重、干重以及维生素C、K、Ca、Fe等含量均高于对照组;叶绿素、蛋白质、Zn、Mg等含量则略低。蓝革屑水解液螯合肥中含有的Cr不会在水培青稞苗中积累而造成青稞苗的铬含量异常升高。该螯合肥能够为植物生长提供必要且丰富的营养成分和大中量、微量元素,促进植物的生长。

The effect of Fe and Zn chelated fertilizer of wet blue shaving hydrolysate on the growth of highland barley seedling was studied by hydroponic experiments. The growth states of highland barley seedlings were observed on the 7th day and 14th day, respectively. The results showed that the height, stem thickness, and leaf width in the experimental group were better than those in the control groups. The higher the concentration of hydroponic solution in the experimental concentration range is, the more significant the effect is. The measurement results of highland barley seedlings showed that the average height, stem diameter, leaf width, wet weight, dry weight, and the contents of vitamin C, K, Ca, and Fe in the experimental group were higher than those in the control groups;while the contents of chlorophyll, protein, Zn, and Mg were slightly lower. The results also indicated that the Cr, contained in this Fe-Zn chelate fertilizer of wet blue shaving hydrolysate, would not accumulate in the hydroponic barley seedling and cause the abnormal increase of chromium content. This chelate fertilizer can promote the growth of highland barley seedling by providing abundant of necessary nutrients, as well as some medium, large and trace elements for plant growth.
