[目的]研究沼液的高效性利用及新型营养液在蔬菜种植上的效果,为沼液的广泛、有效应用提供依据。[方法]利用二次好氧发酵技术,在沼液中添加少量腐植酸,提高沼液的生物活性;通过大棚试验,研究了追施高效沼液营养液对青椒、西红柿和黄瓜3种蔬菜产量和品质的影响。[结果]与对照组和传统施用沼液相比,施用高效沼液营养液明显提高了青椒、西红柿、黄瓜的产量,增幅分别为12.4%、47.4%、19.9%和2.7%、15.9%、9.1%。与传统施用沼液相比,施用高效沼液营养液也明显增加了青椒和黄瓜的Vc含量,增幅分别为16.8%和43.8%。[结论]施用新型高效沼液营养液可有效促进青椒、西红柿和黄瓜产量的增加及改变蔬菜品质,明显提高了沼液的生物活性。
[Objective] The study aimed to study the efficient utilization of biogas slurry and the effect of new nutrient solution on vegetable cultivation, providing the basis for the extensive and effective application of biogas slurry. [Method] With the second aerobic fermentation technology, a small amount of humic acid was added to the biogas slurry to increase the biological activity of the biogas slurry. Through the greenhouse experiment, the effects of topdressing biogas slurry nutrient solution on the yield of three kinds of vegetables such as green pepper, tomato and cucumber And the quality of the impact. [Result] Compared with control group and traditional biogas slurry application, the yield of green pepper, tomato and cucumber increased significantly by 12.4%, 47.4%, 19.9% and 2.7%, 15.9% and 9.1% respectively %. Compared with the traditional application of biogas slurry, the application of high efficiency biogas slurry also significantly increased the Vc content of green peppers and cucumbers by 16.8% and 43.8% respectively. [Conclusion] The application of new efficient biogas nutrient solution could effectively increase the yield of green pepper, tomato and cucumber and change the quality of vegetables, and obviously improve the bioactivity of biogas slurry.
