| 摘 要： | 为了探究空育131的高产优质栽培的合理氮钾配施技术,试验采用随机区组设计,研究不同氮肥与钾肥互作对空育131品质的影响。结果表明:不同肥料处理对水稻碾磨品质、外观品质、营养品质及食味品质的影响显著(P0.05),不同肥料处理对水稻食味评分的影响均达到显著水平,且存在极显著的互作效应,氮钾互作下的食味评分以处理N_3K_4最高,即氮肥180kg·hm~(-2),钾肥135kg·hm~(-2)时为最佳配置,食味达到85.2分,较不施肥提高10.5%,差异达显著水平。

| Abstract: | In order to explore application technology of nitrogen and potassium interaction in high yield and high efficiency cultivation of Kongyu 131,through randomized block design,the effect of different nitrogen and potassium interaction on the main quality of Kongyu 131 was studied.The results showed that effect of nitrogen fertilizer and potash fertilizer on rice taste score reached significant level,and there was significant interaction effect,nitrogen and potassium interaction of taste score to deal with N3K4 maximum,eating reached 85.2,compared with no fertilizer increased 10.5%,and the difference reached significant level. |
