摘要:

【目的】为了明确大蒜在膜下滴灌模式中,不同基追比例和追肥次数对大蒜产量与品质的影响,【方法】选取中牟大蒜为试验品种,在减施无机肥15%的条件下,设置不同的灌溉方式、基追比例和追肥次数。【结果】结果表明在不同的灌溉方式、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,蒜薹和鳞茎产量分别提升了12.68%和14.80%,且大蒜素含量、可溶性蛋白和Vc较传统的大水漫灌分别提升了12.22%、29.80%和10.68%。硝酸盐含量下降10.62%。【结论】研究表明通过膜下滴灌、合适的基追比和追肥次数能够实现大蒜种植的减肥、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, 【Methods】 Zhongmou garlic was selected as the experimental variety, and different irrigation methods, basal dressing ratio and topdressing times were set under the condition of reducing inorganic fertilizer by 15%. 【Results】 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 compared with the traditional flood irrigation. Nitrate content decreased by 10.62%. 【Conclusion】 The study shows that the effects of weight loss, water saving, yield increase and quality improvement of garlic planting can be achieved through drip irrigation under mulch, appropriate ratio of base to topdressing and number of topdressing.
