The waste liquor from the first cooking stage of reed three-stage counter-current batch cooking with ethanol-water process was decolorized by preliming, sulfitation and activated carbon absorption combination method. The preliming temperature, calcium superphosphate dosage, pH Value, Na2SO3dosage in preliming and sulfitation, column height and velocity in activated carbon absorption have effect on decolorization. The results indicated that the 50 mL un decolorized waste liquor have the best decolorizing effect when the preliming temperature was 80°C, calcium superphosphate dosage was 1 g, pH value was 7, Na2SO3dosage was 0.04 mol, column height was 12 cm and velocity was 2mL/min, the decolorized rate of waste liquor could be up to 98.1%.

Npk Fertilization

Nigellia sativa L. plants were fertilized with different rates of NPK fertilizers and sprayed with the growth regulators BL-2142 at 0, 250, 500, and 1000 ppm, CCC at 0, 500, 1000, and 1500 ppm and Multiprop at 0. 12.5, 25, and 50 ppm. The results indicated that both of NPK fertilization and growth regulator treatments enhanced the plant growth in terms of stem diameter, branch number and herb dry weight. Also, these treatments caused early flowering, increased fruit number and seed yield compared to the control plants. The interaction between NPK fertilization and growth regulators had a synergistic effect. The highest seed yield was obtained when the plants received 200, 100, and 25 kg/feddan (feddan = 4200 sqm) of urea, calcium superphosphate and potassium sulphate, respectively and sprayed with CCC at 500 ppm.

Calendula officinalis L. plants were fertilized with urea (46% N), ammonium nitrate (31% N), and ammonium sulfate (20% N) at 0, 25, 50, or 100 kg N/Feddan (4200 m2). The plants also received calcium superphosphate (15.5% P2O5) and potassium sulfate (48% K2O) at 100 and 50 kg/Feddan, respectively. The results showed that fertilizers enhanced vegetative growth and improved flowering aspects compared to control plants. Application of urea at 50 kg N/Feddan gave the highest flower number (119) and flower dry weight (183 g). Moreover, the applied fertilizers increased the content of photosynthetic pigments (chlorophyll a, chlorophyll b, and carotenoids) in leaves and flowers and the N percentage in shoots. Nevertheless, P and K percentages were decreased.
