摘要
为了探究不同土壤类型下施肥处理对垦粳5号产量和品质影响,研究盐碱土与白浆土条件下施用新型复合肥"雷力海補1号"和"微纳米硅"比较试验。结果表明:盐碱土减肥10%,增施雷力肥仍能够保持产量且高出常规化肥4.6%,食味评分提高1.25分,纳米硅肥产量降低6.7%,食味评分提高3.34分,两肥兼施产量降低9.6%,食味评分提高5.3分;白浆土减肥10%,增施雷力肥产量降低5.0%,食味评分提高2.55分,纳米硅肥产量降低11.1%,食味评分下降6.15分,两肥兼施产量降低20.7%,食味评分下降4.29分。盐碱土增施雷力肥产量达到最高,两肥兼施品质最好;白浆土施用常规化肥产量最高,增施雷力肥品质最好。故减肥10%下,增施雷力肥均可在盐碱土与白浆土下稳产并提高稻米品质。
In order to explore the effect of fertilization treatment on the yield and quality of Kenjing5 under different soil types,thecomparative experiment of new compound fertilizers“Lei Li Hai Bu1”and“micro - nano silicon”were studied under saline-alkalisoil and albic soil. The results showed that in the case of 10% weight loss in saline-alkali soil,“Lei Li Hai Bu1”was able tomaintain the yield and higher than the conventional chemical fertilizer 4.6%,the food taste score increased by 1.25 points,thenano-silicon in the yield decreased by 6.7%,the taste score was improved 3.34 points,the production decreased by 9.6% under themixture of two fertilizers,the taste score increased by 5.3 points;in the white soil to lose weight 10% of the case,the fertilefertilizer than conventional fertilizer in the yield of 5% lower,the taste score increased by 2.55 points , nano-silicon fertilizer in theyield of 11.1% lower,the taste score of 6.15 points lower. The yield was 20.7% lower and the taste score of 4.29 points lower in thecase of mixture of two fertilizers. In the saline-alkali soil, the “leiling”fertilizer’ s production could reach the highest, the mixture oftwo fertilizers had the best quality. In the white soil, the conventional fertilizer had the highest yield,“leili”fertilizer had the bestquality. Therefore,the amount of fertilizer was reduced by 10%. Increasing the use of “leili” fertilizer could stabilize the yield andimprove the quality of rice in saline-alkali soil and albic soil.
