摘 要: 为比较研究控失肥(loss control fertilizer,简写为WC)和普通复合肥(normal compound fertilizer,简写为NC)对小麦养分累积及产量的影响,于2015年至2016年在保定市农科院试验田进行了随机区组试验。采用冬小麦品种保麦10号为材料,2种肥料均含20%N、20%P2O5、8%K2O,在播前整地时一次施用,施用量为600 kg/hm2,3次重复。结果表明,不同施肥处理对小麦的干物质和养分积累及其产量性状均产生了显著的影响,WC处理效果显著优于NC. 与NC相比,WC可分别提高小麦千粒重、干物质和产量2.5%、11.0%和6.3%;不同发育时期植株氮、磷、钾元素的吸收量均表现为WC>NC>CK. 肥料的农学效率(agronomic efficiency,AE)提高了23.5%. 同时,土壤中养分的含量也增加。控失肥作为一种新型肥料将对提高小麦产量、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;小麦;控失肥;复合肥;养分累积;产量

Abstract: In order to compare the effects of loss control fertilizer (WC) and normal compound fertilizer (NC) on the nutrition accumulation and yield of wheat, a random block experiment was set at the experimental field of Baoding Academy of Agricultural Science during 2015-2016. The winter wheat variety of Baomai 10 was used as material. Two kinds of fertilizers with the same nutrition content of 20%N, 20%P2O5 and 8%K2O were used and the application rate of fertilizers was 600 kg/hm2, applied once with soil preparation before sowing, 3 reps. The results showed that there were significant differences on dry matter accumulation, nutrition accumulation and yield characteristics with different fertilizer treatments, and the effect of WC treatment was significantly better than that of NC. Compared with NC, the 1 000-grain weight, dry matter and yield of wheat of WC could be increased by 2.5%, 11.0%, 6.3%, respectively. The accumulation amount of N, P, K of wheat plants at different growing stages were shown as follows: WC>NC>CK. The fertilizer agronomic efficiency (AE) was increased by 23.5%, compared with that of the NC treatment. At the same time, the nutrition amount in the top soil was also increased. As a new type of fertilizer, WC will play an important role in improving the yield of wheat, increasing the efficiency of fertilization and protecting the environment.
