Abstract

Abstract:

To provide a reference for rational application of organic fertilizer in green space soil, pot experiments were conducted to investigate the effects of organic fertilizers (mushroom residue, chicken manure, pig manure and green waste) on soil improvement and growth of Zoysia pacifica. The results showed that the contents of organic matter, NPK and total humus carbon in the soil treated with organic fertilizer were significantly higher than those in the control (P<0.05). The contents of soil organic matter, total nitrogen, alkali-hydrolyzed nitrogen and available phosphorus were the highest in the treatment of green waste, which were 10.7, 5.0, 8.6 and 17.4 times of those of the control, respectively. The contents of total potassium and available potassium in the soil were as follows: mushroom residue > chicken manure > green waste > pig manure. The effect of organic fertilizer application on soil aggregates was mainly reflected in macroaggregates, whose relative content was as follows: green waste > pig manure > control > mushroom residue > chicken manure, while the effects on microaggregates were on the contrary. In addition, the fresh and dry weight of Zoysia pacifica in chicken manure treatment were the highest. The contents of chlorophyll a, b and total content in green waste treatment were the highest, which were significantly higher than those of mushroom residue and pig manure treatments, and increased by 25.0%, 33.3% and 27.3% compared with the control. To sum up, green waste is the best organic fertilizer for green space improvement in Shenzhen.

Key words: Green Space, Organic Fertilizer, Soil Improvement, Total Humus Carbon, Soil Aggregates, Zoysia pacifica
