本文介绍了在治理草浆蒸煮黑液中,以黑液为原料制取的植物生长调节剂,对植物生长有明显地促进作用.通过室内及田间小区试验结果表明:施用该调节剂对水稻、玉米和小麦的种子萌发、生长发育、提高产量等均有明显的效果,其中水稻和玉米早熟5天、亩产量分别提高16.4%和11.4%.同时制取调节剂后,可使草浆黑液的COD值降低60%,从而减轻了对环境的污染。
A plant growth regulator has been made from the black liquid from papermaking, which makes it possible for the COD contet of the black liquid to decrease about 60% and improve the environmental pollution level.The experimental results obtained indoor and outdoor test show that the plant growth regulator can significantly promote the germination of the seeds,the growth and the development of the plant,and the precocity of the wheat,the rice and the corn,espccialy the date of the rice and corn harvest is advcnced to 5 adys and the output of the unit of area can be in creased about 16.4% and 11.4% respectively.
