Abstract:

Taking ‘Shanghaiqing’ as the object, the effects of 4 different types of bio-organic fertilizer on the yield, quality and soil properties of greenhouse vegetable were studied to determine the best bio-organic fertilizer type suitable for promotion in Yuhang district, Hangzhou. The results showed that the application of bio-organic fertilizer could promote the growth of green vegetable, increase chlorophyll concentration, improve agronomic traits and increase biological yield. Compared with the control group, the application of Original bio-organic fertilizer had the best effect on promoting growth and increasing yield, with plant height, leaf number, root length and biological yield increased by 19.1%, 11.7%, 27.7% and 9.2%. Senjing bio-organic fertilizer had the second effect, which increased plant height, leaf number, root length and biological yield by 16.0%, 14.5%, 17.5% and 6.6%. In addition, the application of bio-organic fertilizer could enhance soil organic matter and nutrient content. The contents of organic matter, alkali-hydrolyzed nitrogen, available potassium and available phosphorus were increased by 6.7%, 18.4%, 4.9% and 2.2%, respectively. Among them, the application of Tanggu bio-organic fertilizer had the largest increase in soil alkaline hydrolyzed nitrogen and available potassium, and the application of Zhinong bio-organic fertilizer and Original bio-organic fertilizer had the largest increase in soil organic matter content. Based on the above results, the Original bio-organic fertilizer and the Senjing bio-organic fertilizer could be used as the advantageous fertilizers for demonstration and popularization in the greenhouse vegetable in this region.

Key words: bio-organic fertilizer, greenhouse vegetable, growth, yield, soil
