施用增效磷肥对寒地水稻产量形成及应用效果的影响
Effects of Applying Enhanced Phosphate Fertilizer on Yield Formation and Application Effect of Rice in Cold Regions
摘要
Abstract
In order to optimize the formulation of low-content enhanced phosphorus fertilizer as a substitute for conventional 64％diammonium phosphate and improve fertilizer utilization efficiency,this study investigated the effects of applying blended fertilizers containing 53％core masterbatch diammonium phosphate(N-P2O5=14-39)on chlorophyll content,dry matter accumulation and distribution,yield,and yield components of rice in cold region,and the economic benefits were also analyzed.The experiment used a conventional blended fertilizer(CK)with 48％(28-10-10)as the control,and three treatments were established:a blended fertilizer with 48％(28-10-10)(CF1),a blended fertilizer with 48％(26-10-12)(CF2),and a blended fertilizer with 48％(28-8-12)(CF3)all containing 53％core masterbatch diammonium phosphate.The results showed that compared with the control,CF1,CF2,and CF3 treatments significantly increased rice yield by 10.97％,23.73％,and 14.52％,respectively.CF2 exhibited the highest increase,significantly higher than CF1 and CF3.The grains per spike in CF2 and CF3 treatments significantly increased by 20.52％and 14.75％,respectively,and the 1000 grain weight in CF2 treatment significantly increased by 3.26％.However,the seed setting rate across all three treatments significantly decreased.During grain filling stage,the total dry matter weight in CF2 treatment significantly increased by 14.61％,and at maturity,the stem weight,leaf weight,spike weight,and total dry matter weight in CF2 treatment significantly increased by 23.5％,32.92％,33.15％,and 30.15％,respectively.The SPAD value of leaves in CF2 treatment during grain filling stage significantly improved by 4.77％,and the SPAD values of leaves in CF2 and CF3 treatments at maturity significantly increased by 14.02％and 10.10％,respectively.The partial productivity of nitrogen fertilizer in CF1,CF2,and CF3 treatments significantly increased by 15.33％,28.00％,and 19.02％,respectively.The economic benefit of CF2 treatment increased by 5 421.03 yuan per hectare,the highest among all treatments.In conclusion,applying a blended fertilizer with 48％(26-10-12)containing 53％core masterbatch diammonium phosphate can promote rice growth,increase the grains per spike and 1000-grain weight,improve yield and increase benefits.关键词
