啤酒大麦垄畦沟灌节水配套技术研究

Reseaches on the Technical System of Ridge-furrow Irrigation Saving-water in Beer Barley Production

采用正交设计,对啤酒大麦在“垄畦沟灌”种植条件下的次灌溉量、灌溉次数、品种、播种量4个可控因子对产量影响进行了试验研究,结果表明,参试4个因子对产量影响作用次序为灌溉次数、次灌溉量、播种量、品种。确定了高产最优因素位级为:次灌溉量1 200 m3／hm2,生育期灌4次水,选用分蘖成穗率高的多穗型品种(8812)或分蘖力弱的大穗型品种(中品B98-7),播种量150 kg／hm2。并以产量为目标函数,建立了参试4 因子对产量影响的、可用于预报的回归数学模型,在此基础上,提出了单产≥6 000 kg／hm2各不同产量段优化农艺措施组合方案,可以提供生产示范印证。

Adopting orthogonal design,the experiments on four different treatment (irrigation norm, irrigation times, variety, seed quantity),which can be self-controlled was conducted in beer-barely production. The result showed that four factors have different effect on quantity: irrigation times → per-irrigation norm → seed quantity→variety. Better high-quantity constitution were drawn: One is irrigation norm 1200 m3/hm2. four times irrigation during growing,high tiller ability variety (8812), or big tassel variety (Zhongpin B98-7), seed quantity 150 kg/hm2. Per hm2 yield used as target function, the study constructed a set of regression equation analysis system. On the base,the research found a suitable high quantity constitution(6 000 kg/hm2). This can be verified in field plant.
