摘 要: 试验于2014年至2015年在保定市农科院实验基地进行。以谷子品种保谷20为材料,比较研究控失肥和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,在施入相同养分含量(N 144 kg/hm2,P2O5 72 kg/hm2,K2O 72 kg/hm2)的控失肥和普通肥料后,谷子产量、干物质累积和营养元素累积均出现了显著差异,控失肥处理显著优于普通肥料。与普通肥料相比,控失肥可分别提高谷子千粒重、干物质和产量4%、8%和17.1%;控失肥处理的器官营养元素含量高于对照肥料。控失肥处理营养的吸收效率和偏生产力分别比对照肥料高63.4%和10.4%. 控失肥处理比普通化肥处理提高了谷子叶面积指数(leaf area index,LAI)和SPAD值,使得叶片光合强度(Pn)提高了19.5%. 控失肥作为一种新型肥料将对提高谷子产量、提高施肥效益和保护资源环境起到重要作用。
关 键 词: 作物栽培学;谷子;控失肥;养分累积;产量;养分吸收效率

Abstract: Experiments were 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, accumulation of nitrogen, phosphorus and potassium, 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 ordinary fertilizer applied, there were significant differences on millet yield, dry matter accumulation and nutrient accumulation, and the effect of loss control fertilizer treatment was significantly better than that of ordinary fertilizer. Compared with ordinary fertilizer, the 1 000 grain weight, dry matter and yield of millet of loss control fertilizer could be increased by 4%, 8% and 17.1%, 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 leaf area index (LAI) and SPAD also increased, and the leaf photosynthetic rate (Pn) increased by 19.5% for loss control to ordinary fertilizer. As a new type of fertilizer, loss control fertilizer will play an important role in improving the yield of millet, increasing the efficiency of fertilization and protecting the environment.
Key words: crop cultivation; millet; loss control fertilizer; nutrient accumulation; yield; nutrient uptake efficiency
