    摘要:

    为了提高水稻肥料利用率,减少化肥施用量,研究有机无机复混肥的施用效果,设置不施肥(CK)、常规施肥(普通复合肥,氮肥分次施用)(FFP)、等养分有机无机复混肥(一次性施肥)(T1)、等养分有机无机复混肥(氮肥分次施用)(T2)、90% 养分有机无机复混肥(氮肥分次施用)(T3)、80% 养分有机无机复混肥(氮肥分次施用)(T4)共6 个处理,研究有机、无机肥配施对水稻产量及氮磷吸收利用的影响。各处理花后干物质积累量对籽粒贡献率(62.7% ~ 68.5%)均高于干物质转运量对籽粒贡献率(31.5% ~ 37.3%);各处理的实际产量表现为T2>T1>FFP>T3>T4>CK,与FFP 处理相比,T2 和T1 处理增产6.6% 和2.2%,T3 和FFP 处理产量无显著差异;成熟期各处理水稻植株地上部氮素和磷素吸收积累量在籽粒部分占比达到65% 和70% 以上,与FFP 处理相比,T1 处理氮磷肥吸收利用率、氮磷肥农学利用率和氮磷肥偏生产力分别增加了8.9% 和12.9%、0.9% 和3.2%、0.9 和3.2 kg·kg-1,T2 处理氮磷肥吸收利用率、氮磷肥农学利用率和氮磷肥偏生产力分别增加了1.6% 和1.6%、2.6% 和9.6%、2.6 和9.6 kg·kg-1,T3 和T4 处理与FFP 处理差异不显著。有机、无机肥配施能提高氮磷养分吸收利用率,在氮磷钾总养分相同的情况下,一次性施用有机无机复混肥更有利于提高水稻氮磷吸收,在氮肥分次施用情况下,有机无机复混肥增产效果更明显,适当减肥不会降低水稻产量,还可以减少稻田养分残留。

    Abstract:

    In order to improve the fertilizer utilization rate of rice and reduce the amount of fertilizerapplication,the application effect of organic inorganic compound fertilizer was studied. Six different fertilization treatments were setup, including nofertilization(CK),conventional fertilization of common compound fertilizer with nitrogen split-application(FFP),equal nutrient organic inorganic compound fertilizer with one-timefertilization(T1),equal nutrient organic inorganic compound fertilizer with nitrogen fertilizer split-application(T2),90% nutrient organic inorganic compound fertilizer with nitrogen fertilizer split-application(T3),80% nutrient organic inorganic compound fertilizer with nitrogen fertilizer split-application(T4). The effect of organic inorganic compound fertilizer application on rice yield and nitrogen and phosphorus absorption and utilization was studied. The results showed that the contribution rate of dry matter accumulation tograin after anthesis(62.69%-68.48%)was higher than that of dry matter transport tograin(31.52%-37.33%). The actual yield of each treatment ranked as T2>T1>FFP>T3>T4>CK. The yield of T2 and T1 treatments increased by 6.6% and2.2%,respectively,while T3 treatment showed nosignificantdifference,compared with FFP treatments. The uptake and accumulation of aboveground nitrogen and phosphorus in the grain of rice in all treatments accounted for more than 65% and70%,respectively. Compared with FFPtreatment,the uptake and utilization rate of nitrogenand phosphorus fertilizer, the agronomic utilization rate of nitrogen and phosphorus fertilizer and the partial productivity of nitrogen and phosphorus fertilizer in T1 treatment increased by 8.9%and12.9%,0.9%and3.2%,0.9 and 3.2 kg·kg-1,respectively,and those in T2 treatment increased by 1.6%and1.6%,2.6% and9.6%,2.6 and 9.6 kg·kg-1,respectively,while there was no significant difference in T3 and T4 treatment. Combined application of organic inorganic fertilizer can improve the absorption and utilization rate of nitrogen and phosphorus nutrients. In the case of the same total amountof nitrogen,phosphorus andpotassium nutrients, one-time application of organic inorganic compound fertilizer is more conducive to improve the absorption of nitrogen and phosphorus in rice. In the case of split-application ofnitrogen fertilizer,the effect of organic inorganic compound fertilizer is more obvious. Proper reduction fertilization will notreduce the yield ofrice,but also can reduce the nutrient residue in rice fields.
