| 摘 要： | 在栽培方式相同情况下,研究测土配方施肥与常规施肥对超级稻准两优527的生育期、产量及经济效益影响。结果表明:测土配方推荐施肥能延长水稻营养生长期,并协调好营养生长期与生殖生长期的关系,有利于有机物合成,为作物高产奠定基础;测土配方推荐施肥、常规施肥分别比对照增加214.7 kg/667m2、100.3 kg/667m2,增产44.3%、20.69%;测土配方推荐施肥较常规施肥增加114.4 kg/667m2,增产19.56%,均达极显著水平。说明,根据土壤养分分析化验数据,采用合理推荐配方施肥,能增加穴有效穗数、穗实粒数,最大幅度提高超级稻准两优527的产量;在该肥力水平较高的条件下,测土配方推荐施肥比常规施肥增收97.64元/667m2,测土配方施肥比常规施肥经济有效。

| Abstract: | Two application methods of the formula application technique and traditional application technique were used under the same cultivation pattern to study the effects on growth period,yield and economic benefit of Zhunliangyou 527(a hybrid rice variety with super-high yield).The results show that the formula application technique can lengthen its vegetable growth period and adjust the relationship between vegetable and reproductive growth period,which is beneficial to organic synthesis and rice yield.The yield of using the formula application technique and traditional application technique increases by 214.7 kg/667m2(44.3%) and 100.3 kg/667m2(20.69%) compared with CK separately.The yield of the formula application technique increases by 114.4 kg/667m2(19.56%) compared with the traditional application technique and there is very significant difference in rice yield between the formula application technique and traditional application technique.The formula application technique can greatly increase rice yield by raising effective spikes/hole and grains/spike.The economic benefit of the formula application technique is 97.64 yuan higher than the traditional application technique under the higher soil fertility,which indicates that the formula application technique is a better application method with higher benefit effect compared with the tradition application technique. |
