摘要:

为了解控失掺混肥在玉米上的应用效果,开展了控失掺混肥不同施用方法和减量施用的田间小区试验研究。试验共设5个处理,每个处理重复3次,小区面积48 m2,以不施氮肥为对照,测定不同处理对玉米植株养分含量、养分累积吸收量、产量和产量构成因素、氮肥当季利用率等指标的影响。结果表明:在等量施肥条件下,与普通掺混肥处理相比,控失掺混肥处理能够有效提高玉米植株对氮和磷的吸收量、产量、氮素利用率;采用苗期开沟追施施肥方式的增产效果优于种肥同播,玉米产量提高3.67%;采用同样的苗期开沟追施施肥的方式,与普通掺混肥处理相比,控失掺混肥处理的玉米籽粒产量增加3.60%,氮素当季利用率提高24.88%。

Abstract:

In order to understand the application effect of loss-control bulk blended fertilizer on maize, a field plot experiment of different application methods and reduced application of loss-control bulk blended fertilizer is carried out. The experiment sets up 5 treatments, each treatment is repeated 3 times, the plot area is 48 m2, and the treatment without nitrogen fertilizer is used as a control to determine the influence of different treatments on the indicators, including the nutrient content of the maize plant, the cumulative nutrient absorption, yield and yield composition factors, utilization efficiency of nitrogen fertilizer in current season, etc. The results show that under the condition of same amount of fertilization, compared with the common bulk blended fertilizer treatment, the loss-control bulk blended fertilizer treatment can effectively increase the uptake of nitrogen and phosphorus, the yield, and the nitrogen utilization efficiency of the maize plant; the yield increase effect of adopting ditching and topdressing fertilization at seedling stage is better than that of simultaneous sowing of seed and fertilizer, and the yield of maize increases by 3.67%; using the same method of ditching and topdressing fertilization at the seedling stage, compared with the treatment of common bulk blended fertilizer, the maize grain yield of the treatment of loss-control bulk blended fertilizer increases by 3.60%, and the nitrogen utilization efficiency in current season increases by 24.88%.
