在南方典型双季稻种植区,通过2年试验综合评价在有机无机肥配施基础上施用锌肥和石灰对双季稻产量与土壤养分特性的影响,以期提出培肥土壤和提高水稻产量的理想施肥模式。设置有机肥+无机肥(T1)、锌+有机肥+无机肥(T2)、石灰+有机肥+无机肥(T3)、锌+石灰+有机肥+无机肥(T4)4个处理,测定了土壤有效锌、碱解氮、有效锌含量和pH,分析了水稻产量和土壤综合肥力。结果表明:(1)相比T1处理,T2处理显著提高了早晚稻千粒重和结实率,显著增产8.7%,而T3处理不利于水稻稳产,显著降低了千粒重,并在第2年减产(5.6%)显著;T4处理表现出来的产量规律与T3处理类似,均于第2年表现减产。(2)施用锌肥、石灰均有利于提...

The effects of zinc fertilizer and lime on double-season rice yield and soil nutrient characteristics were evaluated in a typical double-season rice growing area in southern China,in order to propose the best fertilization mode for fertilizing local soil and increasing rice yield.It is equipped with organic fertilizer+inorganic fertilizer(T1),zinc+organic fertilizer+inorganic fertilizer(T2),lime+organic fertilizer+inorganic fertilizer(T3),zinc+lime+organic fertilizer+inorganic fertilizer(T4),a total of 4treatments.The indicators of soil available zinc,alkali nitrogen,available zinc,and pH were...
