日光温室黄瓜沼肥综合利用试验

为了大面积推广生态、高效、和谐可持续的现代农业新技术,以日光温室黄瓜为研究对象,研究施用沼肥对黄瓜物候期、营养生长、产量和蚜虫防效的影响。结果表明:与常规施肥相比,施用沼肥后,黄瓜提早上市5 d,延长采收14 d;株高、叶片数、单株鲜质量和干质量分别增长了23.8 cm、6.4片、35.3 g和13.9 g,瓜弯曲率降低了16.7%;黄瓜单株产量约增加23.8%,每公顷总产量增加13.6%、收益增加18.2%;沼液防蚜效果达到96.1%。建议在条件许可的地区大力推广应用。

Experiment on Comprehensive Utilization of Methane Fertilizer on Cucumber in Solar Greenhouse

Abstract: For generalizing modern agriculture new technologies that were ecological, efficient, harmonious and sustainable, using cucumber as the research object, the effects of methane fertilizer on cucumber phenophase, vegetative growth, yield and the control effect of aphids were studied. The results showed that compared with conventional fertilization, the cucumber was on the market earlier for 5 d whose harvest time was extended by 14 d. Plant height, leaf number, fresh weight and dry weight of single plant were increased by 23.8 cm, 6.4 pieces, 35.3 g and 13.9 g, respectively, and the bending rate of melons was decreased by 16.7%. The yield of single plant increased by about 23.8%, and the total yield increased by 13.6% per hectare with the income increased by 18.2%. The control effect of aphids was 96.1%. It was suggested to promote the application of methane fertilizer in the conditional permission area.
