| 摘 要： | 为了提高水分和肥料的利用效率,2015~2016年进行了限水条件下施肥方式对产量构成因素影响的试验。结果表明:底施三元素复合肥+春季浇2水(拔节水+开花水)的产量最高;在相同水分或肥力条件下对穗数的影响较小,穗粒数、不孕小穗数随着水肥条件的不同变化较大,说明在小麦生产中水分和养分是制约小麦生产的主要因素。

| Abstract: | In order to improve the utilization efficiency of water and fertilizer,experiments were conducted in 2015-2016 on the effect of fertilization methods on yield components under the condition of limited water.The results showed that the yield was the highest when the three element compound fertilizer was applied at the bottom and the two water was applied in spring(pulling water and flowering water),and the number of spikes was less affected under the same water or fertilizer condition;the number of grains and sterile spikelets changed greatly different water and fertilizer condition,which indicated that water and nutrient were the main factors restricting wheat production in wheat production. |
