| 摘 要： | 为了研究控失肥在谷子上的施用效果,2015年在保定市农业科学院实验基地进行了田间试验。以谷子品种保谷20为试验材料,在施用等量养分(N 144 kg/hm2,P2O572 kg/hm2,K2O 72 kg/hm2)条件下,分析了施用控失肥与施用普通化肥对谷子干物质累积、氮磷钾养分累积、养分吸收效率和产量等性状的影响。结果表明:与普通化肥处理相比,控失肥处理的谷子千粒重、干物质积累量和产量分别提高4.0%、8.0%和10.4%;各器官营养元素含量高;营养吸收效率和偏生产力分别提高63.4%和10.4%;谷子叶面积指数和SPAD值增大,叶片光合强度提高14.5%。与施入等量养分的普通化肥相比,施用控失肥后谷子的产量、干物质积累和营养元素累积均发生了显著变化,控失肥的效果明显优于普通化肥。

Effects of Loss Control and Conventional Fertilizer on Physiological Characteristics and Yield of Millet |

| Abstract: | In order to study the effect of loss control fertilizer on millet,field experiment was conducted at the Experimental Station of Baoding Academy of Agricultural Sciences during 2014-2015. The effects of loss control and ordinary fertilizer on accumulation of dry matter,nitrogen,phosphorus and potassium accumulated amount, nutrient uptake efficiency and yield of millet were studied using millet hybrid Baogu 20 as material. The results showed that with the same nutrient amount (N 144 kg/hm2,P2O5 72 kg/hm2,K2O 72 kg/hm2) of loss control and or-dinary fertilizer applied,there were significant differences on millet yield,dry matter and nutrient accumulation, and the effect of loss control fertilizer treatment was significantly better than that of ordinary fertilizer. Compared with ordinary fertilizer,1 000 grain weight,dry matter accumulation and yield of millet of loss control fertilizer could be increased by 4.0%,8.0% and 10.4%,respectively. The content of nutrient elements in organs of loss control fertilizer treatment was higher than that of the ordinary fertilizer,and the nutrient uptake efficiency and partial productivity were increased by 63.4% and 10.4% of that of contrast fertilizer. Plant LA I and SPAD were al-so increased,and the leaf Pn was increased by 14.5% for loss control to ordinary fertilizer. As a new type of fer-tilizer,loss control fertilizer will play an important role in improving the yield of maize, increasing the effi-ciency of fertilization and protecting the environment. |
