摘要:

【目的】探明膜下滴灌大蒜适宜基追比例和追肥次数。【方法】选取中牟大蒜为试验对象，研究在减施无机肥15%的条件下，不同灌溉方式、基追比例和追肥次数对大蒜产量和品质的影响。【结果】在不同灌溉方式、基追比和追肥次数中，膜下滴灌底肥60%和追肥40%处理增产效果最明显，蒜薹和蒜头产量分别提升了12.68%和14.80%，且大蒜素量、可溶性蛋白、Vc较传统大水漫灌分别提升了12.22%、29.80%、10.68%，硝酸盐量下降10.62%。【结论】故通过膜下滴灌采用基肥60%+追肥40%，追肥分5次施入能够实现大蒜种植减肥、节水、增产和提升品质的效果。

Abstract:

【Objective】In order to determine the effect of different basal dressing ratio and topdressing times on garlic yield and quality in the drip irrigation mode under mulch, 【Method】Selecting Zhongmou garlic as the experimental variety, the effects of different irrigation methods, basal and topdressing ratios, and topdressing times on garlic yield and quality were studied under the condition of reducing inorganic fertilizer application by 15%. 【Result】The results showed that among different irrigation methods, basal dressing ratio and topdressing times, the treatment of 60% basal fertilizer and 40% topdressing under mulch drip irrigation had the most obvious effect on yield increase, the yield of garlic sprouts and bulbs increased by 12.68% and 14.80% respectively, and the allicin content, soluble protein and Vc increased by 12.22%, 29.80% and 10.68% respectively, and nitrate content decreased by 10.62%. 【Conclusion】The study showed that the effects of weight loss, water saving, yield increase and quality improvement of garlic planting could be achieved through drip irrigation under mulch, appropriate ratio of base to topdressing and number of topdressing.
