为确定不同浓度的沼液喷施黄瓜的效果，选用不同浓度的沼液对黄瓜进行叶面喷施，测定其对黄瓜生长进程和产量的影响。研究结果表明，利用沼液喷施后黄瓜果实品质好，瓜条鲜嫩，商品性状好，生长势强、整齐一致，表皮亮绿，瓜条顺直，而且病虫害明显轻于对照，其中浓度为40%的沼液喷施后黄瓜产量最高，达到8463.65 kg/667 m2，可溶性固形物含量达到3.0%，较清水对照分别提高10.19%和36.36%；VC 含量为8.5 mg/100 g，比对照提高8.97%。%We carried out the experiment to study the effects of spraying different concentrations of biogas slurry on cucumber growth and yield in protected field. The results showed that, spraying biogas slurry could improve fruit quality of cucumber, and the fruit was straight and bright green. The plant had stronger growth potential, and plant disease and insect incidence was reduced significantly. While sprayed with 40% biogas slurry, the cucumber yield was highest of 8 463.65 kg/667 m2 and the soluble solids content reached to 3.0% , which were increased by 10.19% and 36.36%compared with the control respectively. In addition, the vitamin C content was 8.5 mg/100 g, which was 8.97% higher than that of the control.
