ABSTRACT

Lignin sulfonate, a by-product of pulp or fiber pulp production using the sulfite method, is directly extracted in its paper mill waste red liquor and is a non-toxic resource with a wide range of sources, low cost and renewable. There are many studies on lignin applications, and from the end of the nineteenth century to the present, more than two hundred lignin products have been developed internationally [1-2], mainly for dye dispersants, concrete admixtures, water treatment agents, animal feed additives, drilling fluid diluents, tertiary oil recovery aids, and various adhesives and complexing agents [2-10].Nanotechnology was combined with low-cost and abundant sodium lignin sulfonate to prepare it into nano-sodium lignin sulfonate formulations by nanotechnology as a way to improve its ability as a growth regulator, and to study and investigate the effects of nano- and non-nano-sodium lignin sulfonate as a growth regulator on the seedling growth and development of wheat by measuring the morphological and physiological and biochemical indices of seedling growth and development.The main research works were (1) the preparation of nano-sodium lignosulfonate formulations; (2) the morphological and structural characterization of nano-sodium lignosulfonate formulations by laser pens, scanning electron microscopy and optical microscopy;The results showed that (1) the prepared nano-adsorbents exhibited homogeneous fine particle size, uniform dispersion, and particle size in the range of about 20 nm to 60 nm under room temperature neutral conditions; (2) the adsorption of the nano-formulations was higher than that of the non-nanoproducts under the same conditions. (3) The effect of suitable concentration of adsorbent solution treatment of sodium nanolignosulfonate preparation on germination rate, root length and seedling length of mung bean seedlings was significantly promoted and chlorophyll content was increased compared with the control group. (4) This study found that sodium lignosulfonate has the efficacy of plant growth promoter, and also measured that plant seedlings treated with sodium nanolignosulfonate preparation have enhanced growth and development, which provides an enlightening exploration for future development of organic agriculture and green agricultural production, and environment-friendly growth regulators.
