Preliminary Study on Effects of Combination of Chitooligosaccharide and Humic Acid on Growth of Wheat Seedlings
Using wheat"Jimai 22"seeds as material,the hydroponic experiment of wheat seedlings was carried out.From the perspective of biostimultin compounding,chitoligosaccharide products with good growth effect on wheat seedlings were screened first,and then the selected chitoligosaccharide products were combined with humic acid to study the effects of compound products on the growth of wheat seedlings.The results showed that,compared with blank control,the combination of chitooligosaccharide and humic acid combination sinnificantly improved wheat seedling height and main root length.Compared with the use of humic acid alone,some of the combination products sinnificantly improved wheat seedling height and main root length.The maximum effects of the combination products on wheat seedling height and main root length were 8.7%and 12.4%,respectively.
