灌水频率对枸杞品质、产量和耗水特性的影响

以枸杞为试验材料，研究灌水频率对枸杞耗水量、产量和品质的影响，确定枸杞的水分生产函数。结果表明：枸杞对水分的消耗基本呈现为秋果采收期和秋果生长期小、营养生长期较大、高峰为盛果期和盛花期的特点；通过对枸杞产量和耗水量进行拟合，得出水分生产函数为y=-1.2162x2+1461.07x-436857 (R2=0.7673)，当耗水量为达到600.68 mm，产量达到1965.47 kg/hm2，即当灌水次数达到5次时，不仅可获得最高产量，使水分利用效率相对较高，同时也获得了较好的枸杞品质，实现了高产与高效的统一。

Research on the Quality, Yield and Water Consumption Characteristic of Lycium barbarum by Irrigation Frequency

With Lycium barbarum as test material, examined the effect of different irrigation on yield and quality of irrigation frequency, Lycium determine water production functions. Results showed that the wolfberry autumn fruit harvested in the water consumption of basic rendering and Autumn fruit growth stage for small, large vegetative growth, peak period of full productive age and characteristics of florescence; by fitting the yield and water consumption of Lycium barbarum and concluded that water production function was y=-1.2162x2+1461.07x-436857 (R2=0.7673), when water consumption to reach 600.68 mm, production reached 1965.47 kg/hm2, where irrigation frequency up to five times. Not only for the highest yield, so that relatively high water use efficiency, but also access to a better quality of Lycium barbarum, achieving high yield and efficient and uniform.
