有机肥等氮替代化肥对设施辣椒土壤有效态养分及果实的影响
Effects of Organic Substitution with Equivalent Nitrogen Content on Soil Available Nutrients and Fruit Quality of Facility-grown Peppers
摘要
Abstract
To explore an effective fertilization strategy for facility pepper production in Jingyuan,improve fertilizer-use effi-ciency,increase farmers'income,and promote cost reduction and efficiency improvement in agriculture,7 treatment were established,including conventional fertilization(N 414.00 kg/ha,P2O5 284.40 kg/ha,K2O 393.75 kg/ha),optimized fertilization(N 379.50 kg/ha,P2O5 300.60 kg/ha,K2O 210.00 kg/ha),and different rates of organic fertilizer substitution for nitrogen fertilizer,and the effects on soil available nutrients,fruit quality,yield,and economic benefit of facility peppers were investigated.Result showed that the treatment with organic fertilizer substituting 15%of nitrogen under optimized fertilization resulted in the highest soil available manganese,iron,and copper contents,reaching 14.63,15.07,and 1.64 mg/kg,respectively,which were 17.04%,48.91%,and 25.19%higher than those in the unfertilized control.The treatment with organic fertilizer substituting 30%of nitrogen under optimized fertilization resulted in the highest soil available zinc content at 4.15 mg/kg,representing an increase of 131.84%compared with that in the unfertilized con-trol.The available boron content under all treatments showed a decreasing trend compared with the level before the experiment.Com-pared with the unfertilized control,the protein content and vitamin C content of pepper fruit decreased under all fertilization treatment.Among them,the treatment with organic fertilizer substituting 30%of nitrogen under optimized fertilization showed relatively higher protein content(15.2 mg/kg)and vitamin C content(71.67 μg/kg),decreasing by 6.17%and 4.82%compared with those in the unfertil-ized control,respectively.The highest total sugar content was also observed in the treatment with organic fertilizer substituting 30%of nitrogen under optimized fertilization(10.3 mg/kg),which increased by 11.96%compared with that in the unfertilized control.Pepper yield and economic benefit were highest under the treatment with organic fertilizer substituting 30%of nitrogen under optimized fertil-ization,with a yield of 57 411.31 kg/ha,representing a 28.57%increase compared with the unfertilized control.The net income reached 147 273.01 Yuan/ha,with an input-output ratio of 3.26.Based on the comprehensive evaluation of yield stability,soil im-provement potential,and economic benefit,the substitution of 30%nitrogen with organic fertilizer under optimized fertilization is rec-ommended as the most suitable fertilization strategy for facility pepper production in the Jingyuan area.关键词
