摘要
运用2因素5水平正交组合设计,研究水分、肥料对树莓生长及产量和品质的影响;运用主成分分析方法,综合产量、品质、水分、肥料利用效率,分析树莓在小管出流条件下的灌溉施肥制度。结果表明:树莓的最适施肥量为18.00kg/667m2,树莓最适宜的土壤含水量下限控制在33%以上,实测灌水量为298.20m3/667m2左右。
The influence of different water and fertilizer coupling on the growth,the yield and the fruit quality of the raspberry was studied by using quadratic regression orthogonal combination design.The irrigation and fertilization system under the condition of smalltube flow was obtained by using principal component analysis and considering the yield,the quality,the water,and the utilization ratio of the fertilizer.The results showed that the optimal fertilizer rate of raspberry was 18.00 kg/667m2,the optimal lower control limit of the soil water content was 33% and the actual irrigation quantity was 298.20 m3/667m2.
