主要栽培措施对优质小麦贵农18 号产量和品质的影响

为了找到优质小麦贵农18 号的最优栽培措施组合，选择对优质小麦贵农18 号农艺性状和产量影响较大的播种密度、基肥施用量、追肥施用量和微肥施用量为试验处理因素，分别设置3 个水平，采用4 因素3 水平的正交试验设计方案，开展主要栽培措施对优质小麦贵农18 号产量和品质影响的研究。结果表明，A2B3C3D1处理即播种量120 kg/hm2、基肥施用量120 kg/hm2、追肥施用量90 kg/hm2、锌肥施用量7.5 kg/hm2的各项农艺性状指标综合表现最好，产量最高，品质最优，是适合贵农18 号小麦生产的最优栽培技术措施。

Effects of main cultivation measures on yieldand quality of Guinong o. 18

In order to find out the best cultivation measure of Guilong No.18, which is a wheat variety suitable forspreading in Guizhou. Seeding density base fertilizer capacity supplemental fertilizer capacity and zinc fertilizer capacitywere chosen as four factors in this experiment, and each of them had 3 levels. The orthogonal test method was used in thisexperiment, the effects of main cultivation measures on yield and quality of Guinong No. 18 was studied. The result showedthat it would be the best cultivation measure when seeding density was 120 kg/hm2, base fertilizer was 120 kg/hm2,supplemental fertilizer was 60 kg/hm2, and zinc fertilizer was 7.5 kg/hm2.
