施用增效磷肥对寒地水稻产量形成及应用效果的影响OA
Effects of Applying Enhanced Phosphate Fertilizer on Yield Formation and Application Effect of Rice in Cold Regions
为明确低含量增效磷肥替代常规64％磷酸二铵的优化配方,提高肥料利用效率,应用含核心母粒二铵53％(N-P2O5=14-39)的掺混肥,探究该掺混肥对寒地水稻叶绿素含量、干物质积累与分配、产量及产量构成的影响,并对其产生的效益进行分析.以配制的常规掺混肥48％(28-10-10)作为对照(CK),另设置3个试验处理,分别为含核心母粒二铵53％配制的掺混肥48％(28-10-10)(CF1)、掺混肥48％(26-10-12)(CF2)和掺混肥48％(28-8-12)(CF3).结果表明,与CK相比,CF1、CF2和CF3处理的水稻产量分别显著增加10.97％、23.73％和14.52％,CF2的增幅最高,显著高于CF1和CF3;CF2和CF3处理的每穗粒数分别显著增加20.52％和14.75％,CF2的千粒重显著增加3.26％,而3个处理的结实率则均显著降低;CF2处理灌浆期的总干物质量显著增加14.61％,成熟期的茎质量、叶质量、穗质量和总干物质量分别显著增加23.5％、32.92％、33.15％和30.15％;CF2处理灌浆期的叶片SPAD值显著提高4.77％,CF2和CF3处理成熟期的叶片SPAD值分别显著提高14.02％和10.10％;CF1、CF2和CF3处理的水稻氮肥偏生产力分别显著提高15.33％、28.00％和19.02％;CF2处理的效益增加5 421.03元·hm-2,增幅最高.综上所述,施用含核心母粒二铵53％配制的掺混肥48％(26-10-12)可以促进水稻生长,增加每穗粒数和千粒重,进而提高产量,增加种植效益.
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.
