通过河磷钾化田用量三因素五水平重复D-饱和设计试验;氮肥用量及运筹三因素四水平重复D-饱和设计试验以及大麦拔节孕德肥运筹试验,结果表明,氮肥对促进苏引麦2号啤麦分蘖,提高成穗,增加实粒数和粒重影响最大,基施磷钾肥效果不明显,但钾肥可提高抗逆性,减轻冻害.苏引麦2号施肥量为N14~15kg/亩,P2O53~4kg/亩,K2O4~5kg/亩.氮肥作基肥、苗肥、拔节肥的比例为5:2:3.过节孕穗期配施磷钾肥增产效果更为明显.
Through three-factor and five-level repeated D-saturation design experiments, three-factor-four-level repeated D-saturation design and three-factor four-level design, and the experiment of malting and jointing of barley, the results showed that nitrogen fertilizer No.2 beer malt tiller, increased into spike, increasing the number of solid particles and grain weight of the greatest impact, based on the effect of phosphorus and potassium is not obvious, but potassium can improve the resistance and reduce the frost damage. Su-Mai 2 fertilizer amount of N14 ~ 15kg / mu, P2O53 ~ 4kg / mu, K2O4 ~ 5kg / mu. Nitrogen fertilizer for basal, seedling, jointing fertilizer ratio of 5: 2: 3. Festive bazaar with phosphorus and potassium fertilizer production more obvious effect.
