Effects of Humic Acid Optimized Nutrition Package Fertilizer on the Growth and Yield of Cucumber and the Soil Physicochemical Properties
The effects of conventional fertilization,conventional fertilization coupled with humic acid bio-organic fertilizer,and humic acid optimization nutrition package fertilizer on the growth and yield of cucumber and the soil physicochemical properties were compared using cucumber as experimental material.The results showed that,compared with the conventional fertilization treatment,the application of humic acid optimization nutrition package fertilizer treatment had the best plant growth,soil physical and chemical properties were significantly improved,soil organic matter content was increased by 1.6 g/kg,while available nitrogen,phosphorus and potassium contents rose by 16 mg/kg,8 mg/kg and 3 mg/kg,respectively.Additionally,soil bulk density was decreased by 0.06 g/m3 whereas pH was increased by 0.4 units.Cucumber yield reached its best at 5805.8 kg/667 m2 under this treatment,which was an increase of 1188.9 kg/667 m2 compared with conventional fertilization.This resulted in a yield increase by 25.7%and an income increase by 951.12 yuan/667 m2.The treatment involving conventional fertilization combined with humic acid bio-organic fertilizer had the second best plant growth,which increased production by 744.5 kg/667 m2 compared with conventional fertilization treatment,with a yield increase rate of 16.1%,demonstrating remarkable effects in both production and economic benifit.
