Optimization of irrigation and fertilization strategies for greenhouse cucumber production in Northern China
摘要
Abstract
[Objective]Efficient irrigation and fertilization management are critical for improving yield and resource use efficiency in greenhouse vegetable production.However,optimal irrigation and fertilization strategies for greenhouse cucumber production in Northern China remain elusive.This paper aims to address this technological gap.[Method]Irrigation and fertilization were based on soil water dynamics such that whenever soil water content decreased to 65%of the field capacity,the soil water was topped up by irrigating 80 m3/hm2(W1),160 m3/hm2(W2)or 240 m3/hm2(W3)of water.For each irrigation treatment,there were three fertilization levels,with the mass of fertilizer applied during each irrigation event being 1/2 000(F1),1/1 500(F2)and 1/1 000 of the mass of irrigated water.In each treatment,we measured water use efficiency(WUE),partial factor productivity of fertilizer(PFP),cucumber yield,quality and flavor.[Result]W3F3 produced the highest yield,reaching 340.59 t/hm2.When irrigation was the same,decreasing the fertilizer-water ratio generally increased total fertilizer application and WUE,but reduced PFP.Increasing the fertilizer-water ratio from 1/2 000 to 1/1 000 increased fertilizer application and WUE by 93.55%and 15.27%for W1,95.45%and 4.47%for W2,and 74.32%and 7.72%for W3,respectively,while reducing PFP by 42.00%for W1,47.59%for W2,and 39.28%for W3.Averaging over all fertilization treatments,increasing irrigation from W1 to W3 increased fertilizer application and cucumber yield by 8.31%and 71.84%,respectively,and reduced WUE and PFP by 33.82%and 37.27%,respectively.Membership function and ranking analysis showed that W1F3 improved cucumber quality and flavor the most.Entropy-power-TOPSIS analysis showed that W1F2 achieved the highest comprehensive score.[Conclusion]Irrigating 240 m3/hm2 of water whenever soil water content decreased to 65%of the field capacity with the mass of fertilizer applied in each irrigation event being 1/2 000 of the irrigated water gave the highest cucumber yield.In contrast,irrigating 80 m3/hm2 of water when soil water content dropped to 65%of the field capacity with the mass of the fertilizer applied in each irrigation event being 1/1 000 or 1/1 500 of the irrigated water was most economical.These results provide practical fertigation guidance for greenhouse cucumber production in Northern China.关键词
