Meta-analysis of the Effects of Combined Application of Organic and Inorganic Fertilizers on the Production of Plant Crop in Sugarcane
[Objective]Quantitative analysis was carried out by integrating the results of previous studies to provide insights into green fertilization and efficient production of sugarcane.[Methods]Based on CNKI,Wanfang data and Web of Science database,this paper selected'sugarcane','yield'and'organic fertilizer'as keywords to combine each other for literature retrieval and corresponding data extraction.Meta-analysis method was used to analyze the comprehensive effect of organic and inorganic combined application on sugarcane yield of plant crop and the factors affecting the yield effect,with single chemical fertilizer treatment as the control and response ratio as the effect value.[Results]The combined application of organic fertilizer and inorganic fertilizer could significantly improve the agronomic traits,yield and sucrose content of plant crop in sugarcane.The growth rates(Z)of sugarcane yield and sucrose content were 10.72%and 2.33%,respectively.From 2003 to 2023,the combined application of organic and inorganic fertilizers had a significant effect on the increase of sugarcane yield.Except for Yunnan sugarcane region,the yield-increasing effect of sugarcane in the other four provinces(autonomous regions)was significant.The combined application of organic and inorganic fertilizers showed a significant yield-increasing effect on sugarcane in five common sugarcane fields,and the lower the soil fertility and soil pH,the more significant the yield-increasing effect.Among the five main sugarcane varieties in mainland China,the combined application of organic and inorganic fertilizers had the highest yield-increasing effect on Yunzhe 081609(Z=22.94%)and the lowest yield-increasing effect on XTT22(Z=7.99%).The yield-increasing effect of animal-derived organic fertilizer combined with chemical fertilizer on sugarcane(Z=13.13%)was better than plant-derived organic fertilizer combined with chemical fertilizer(Z=11.48%).The yield-increasing effect of combined application of organic and inorganic fertilizers on sugarcane showed an increasing trend with the increase of planting spacing and inorganic nitrogen fertilizer input,respectively.The yield-increasing effect of sugarcane reached the highest(Z=15.79%,Z=13.62%)when the planting row spacing was greater than 1.15 m and the inorganic nitrogen fertilizer input was greater than 300 kg/hm2,respectively.[Conclusion]The combined application of organic fertilizer and inorganic fertilizer can significantly improve the agronomic and economic traits of sugarcane from plant crop,which is an efficient fertilization technology.At the same time,the yield-increasing effect of combined application of organic fertilizer and inorganic fertilizer on sugarcane plant crop is significantly affected by planting year,planting area,soil type and physical and chemical properties,varieties and cultivation practices,so it is necessary to formulate cultivation management strategies according to local conditions.
