摘要: |
【目的】为了研究微纳米气泡水(Micro-nano Bubble Water, MNBW)滴灌条件下,滴灌频率、滴灌施肥量对甜瓜产量与品质的影响,提出适合设施甜瓜栽培的MNBW滴灌模式。【方法】本文以设施甜瓜为供试对象,采用地下滴灌系统进行微纳米气泡水(Micro-nano Bubble Water, MNBW)灌溉。研究了MNBW和传统地下水(Conventional Groundwater,CGW)两种滴灌水源、两种滴灌施肥量(100%和80%传统滴灌施肥量)、三种滴灌频率(1次/3d、1次/7d、1次/15d)等因素耦合对甜瓜产量、品质和灌溉水利用效率(IWUE)的影响。【结果】结果表明:使用MNBW滴灌可以实现肥料减施,削减20%传统滴灌施肥量可以大幅提高甜瓜的产量(增幅最高可达56.4%)和IWUE(增幅最高可达67.7%),可溶性糖、维生素C、可溶性固形物的含量也提升显著;灌溉频率也会影响MNBW滴灌的应用效果,1次/3d的高频滴灌下对甜瓜的品质提升最为明显,甜瓜的产量、株高和茎粗也有所提升。【结论】推荐使用1次/3d的MNBW滴灌结合80%传统滴灌施肥量作为设施甜瓜微纳米气泡水滴灌模式。但如果未恰当地采用未腐熟牛粪作为底肥,MNBW滴灌反而会大幅降低甜瓜的产量、品质与IWUE。研究可为MNBW灌溉技术在设施生产中的应用和推广提供支撑。 |

【Objective】In order to study the effects of drip irrigation frequency and drip irrigation fertilization levels on the yield and quality of muskmelon with Micro-nano Bubble Water (MNBW) drip irrigation. And proposing a suitable MNBW drip irrigation model for facility muskmelon cultivation.【Method】This paper studied the effects of two sources of irrigation water: MNBW and Conventional Groundwater (CGW), three MNBW irrigation frequencies (once every three days, seven days and fifteen days, which is referred to P3,P7,P15)and two different drip irrigation fertilization levels (100%, 80% ,which is referred to F80,F100) on the yield, quality and irrigation water use efficiency(IWUE) of muskmelon.【Result】The results showed that using MNBW can reduce the amount of fertilizer. Even if the amount of drip irrigation fertilizer is reduced by 20%, the yield (Up to 54.6%)and IWUE(Up to 67.6%)can be increased significantly. Soluble sugar, Organic acid, vitamin C and soluble solids also increased significantly. Different frequencies affected the application effect of MNBW irrigation, and high frequency (P3)MNBW irrigation can increase the quality of muskmelon.【Conclusion】The recommended MNBW mode for muskmelon is the frequency of once every 3 days , combined with 80% conventional drip irrigation fertilizer. However, if immature manure is used as the fertilizer, MNBW irrigation will instead inhibit the growth of muskmelon and reduce the yield, quality and IWUE . The research can provide support for the application and promotion of MNBW irrigation technology in facility production. |
