Effects of Liquid Organic Fertilizers on Fruit Quality and Soil Fertility of Bingtang Orange
This experiment investigated the effects of liquid organic fertilizers on the soil fertility and fruit quality of Bingtang orange(Citrus sinensis).The results showed that liquid organic fertilizer had a positive effect on soil fertility and fruit quality compared with the control group(CK).The samples were divided into four treatments based on a base fertilizer of 3 kg of compound fertilizer:no organic fertilizer(CK),solid organic fertilizer(CF),YHY liquid organic fertilizer(T1),and YLG liquid organic fertilizer(T2).The study found that compared with CK,liquid organic fertilizer increased the organic matter,alkali-hydrolyzable nitrogen,available phosphorus,and available potassium in soil,increased the soil water-stable aggregates greater than 0.25 mm in particle size,decreased the rate of soil aggregate destruction,and improved the yield and quality of Bingtang orange fruits.These findings suggested that liquid organic fertilizer could be a viable alternative to solid organic fertilizer.Based on the evaluation of fertilizer cost,soil improvement,leaf nutrient status,and fruit quality of Bingtang orange,it was concluded that liquid organic fertilizer could be used as a short-term alternative or follow-up to solid organic fertilizer in the cultivation of Bingtang orange.
