摘要：为了研究沼液药肥一体化水剂配方和功能。方法:首先将磁石和石膏与沼液混合,再加硅藻土净化;然后以水不溶物含量为指标,通过正交试验筛选氮磷钾矿质养分的最佳添加量,将之与小檗碱配合制备成沼液药肥一体化水剂;测定其对番茄灰霉病菌的抑制效果及对白菜生长的影响。结果表明:沼液净化后,其中铁、锰、锌含量增加,铜离子及重金属离子含量明显降低;以0.01%小檗碱、17%尿素、9%磷酸二氢钾、10%硝酸钾和8%黄腐酸(沼液补至100%)制备的沼液药肥一体化水剂,其N∶P2O5∶K2O质量比:8.51∶4.18∶7.87,N、P2O5、K2O总和即养分含量为205.6 g/L,能满足作物对养分的需求。抑菌实验表明,沼液药肥一体化水剂对番茄灰霉病菌有较强抑制作用,EC50为12.12μg/m L,是小檗碱水剂(抑制番茄灰霉病菌的EC50为398.11μg/m L) EC50的3.04%。沼液药肥一体化水剂稀释150倍后(即养分含量为1.67 g/L)喷施白菜能有效加速植株生长。结论:该研究为提高沼液抑菌效果和肥效,开发以沼液和小檗碱为主要原料的药肥一体化水剂提供科学依据。
The objective of our study is to refine the formula and to examine the function of medicine and fertilizer integrated aqua.First,the biogas slurry was purified by mixing with the magnet,gypsum and diatomite.The ratio of mineral nutrients N,P,K were optimized by orthogonal test using the content of water-insoluble as an index,and the optimum formula was combined with berberine to prepare the medicine and fertilizer integrated aqua.The inhibitory effect of this novel medicine and fertilizer integrated aqua on Botrytis cinerea and its impact on the growth of Chinese cabbage were assayed. Results showed that after purification,the concentration of Fe,Mn and Zn elements increased while Cu and other heavy metal ion sharply declined.In the medicine and fertilizer integrated aqua（ 0.01% berberine,17% urea,9% potassium dihydrogen phosphate,10% potassium nitrate and 8% fulvic acid,followed by a fill-up of biogas slurry）,the mass ratio of N∶ P2 O5∶ K2 O was 8.51∶ 4.18∶ 7.87,and the sum of N,P2 O5 and K2 O means that the nutrient content was 205.6 g/L,which could meet the crop＇s nutrient needs.The results of antibacterial tests proved that medicine and fertilizer integrated aqua had a strong inhibitory effect on Botrytis cinerea,EC50 could be reduced to 12.12 μg/mL,which was reduced by 3.04% compared with the EC50 of the berberine aqua（ 398.1 μg/mL）.The growth of Chinese cabbage was effectively promoted by spraying 150 times diluted medicine and fertilizer integrated aqua（ the nutrient content is 1.67 g/L）.This study provided a scientific reference for improving antibacterial effect and fertilizer efficiency of biogas slurry and developing medicine fertilizer with biogas slurry and berberine as the main raw material.
