控失肥对夏玉米产量及养分积累的影响

Effects of Loss Control Fertilizer on Yield and Nutrient Accumulation of Summer Maize

为了研究控失肥在玉米上的施用效果,以玉米杂交种郑单958为试验材料,在相同施肥量(N、P_2O_5、K_2O施肥量分别为144、72和72 kg/hm^2)条件下,以施用普通化肥为对照,分析了施用控失肥对玉米产量、干物质累积、氮磷钾养分积累和养分吸收效率的影响。结果表明:控失肥处理的玉米产量、干物质积累量和营养元素积累量均显著优于普通化肥,各器官的营养元素含量高于对照肥料;营养元素的吸收效率和偏生产力均显著高于常规化肥。控失肥作为一种新型肥料,对提高玉米产量和施肥效益,以及保护环境资源起到重要作用。

In order to study the effect of loss control fertilizer on maize,field experiment was conducted with maize hybrid Zhengdan 958 as test material, and maize yield, dry matter accumulation, N, P, K nutrient accumulation,and its uptake efficiency were analyzed with the same nutrient amount （N,P2O5,K2O content were 144,72 and 72 kg/hm^2,respectively） of loss control and common fertilizer. The results showed that the grain yield,dry matter and nutrition accumulation of loss control fertilizer treatment （FC） were significantly better than those of common fertilizer treatment （NF） . The content of nutrient elements in organs of FC was higher than that of NF, and the nutrient uptake efficiency and partial productivity of FC were significantly higher than those of NF. As a new type of fertilizer, loss control fertilizer will play an important role in improving the yield of maize,increasing the efficiency of fertilization and protecting the environment.
