缫丝汰头中含有丰富的废丝废茧废弃蛋白质,废弃蛋白经酸水解后,得到的氨基酸水解液中游离的氨基酸N,可为小球藻生长提供丰富的来源。以小球藻生物量为指标,通过单因素试验研究不同浓度的氨基酸水解液、K2HPO4、MgSO4、Na2EDTA、光合细菌和芽孢杆菌对小球藻生长的影响,得到小球藻生长的最适浓度,制备出一种以废丝废茧为原料的氨基酸肥水剂,配方为:pH值7.0～7.2、浓度83.33%的氨基酸水解液10 mL,每200 mL肥水剂含K2HPO40.8 g、MgSO4.7H2O 2.0 g、Na2EDTA 0.025 g、1.02×104CFU光合细菌∶5.4×104CFU芽孢杆菌=1∶1。
Silkworm trout head is rich in waste waste silk waste protein, waste protein by acid hydrolysis, the amino acid amino acids obtained in the free amino acid N, can provide a rich source for the growth of chlorella. Chlorella biomass was used as an index to study the effects of different concentrations of amino acid hydrolyzate, K2HPO4, MgSO4, Na2EDTA, photosynthetic bacteria and Bacillus on the growth of Chlorella vulgaris by single factor experiment to get the optimum concentration of Chlorella growth, The preparation method comprises the following steps: preparing an amino acid fertilizer with waste silk waste cocoon as raw material, and the formula is as follows: 10 mL of amino acid hydrolyzate with the pH value of 7.0-7.2 and a concentration of 83.33%, and each 200 mL of fertilizers contains K2HPO40.8 g, MgSO4.7H2O 2.0 g, Na2EDTA 0.025 g, 1.02 × 10 4 CFU Photosynthetic bacteria: 5.4 × 10 4 CFU Bacillus = 1: 1.
