小管出流条件下树莓适宜灌溉制度研究

摘要

The effect of soil water on raspberry was determined in the measuring pits under the proof-rain cover. Principal component analysis was applied to comprehensively analyze and evaluate fruit quality, yield, water use efficiency indicators under small tube irrigation. The results show that raspberry fruit quality is the best, its yield is high, water use efficiency is high if soil water is kept between 50%～60% of field capacity during the whole growth period.%为获得树莓的小管出流适宜灌溉制度,在滑动式防雨棚内的测坑中进行小管出流灌水方式下土壤水分对树莓生产的影响试验。采用主成分分析方法综合评价小管出流条件下土壤水分对树莓品质、产量、水分利用效率的影响,结果表明：在树莓整个生育期内,当土壤水分控制在田间持水量的50%～60%时,树莓的产量高、品质好、水分利用效率高,可达到高产、高效、优质的目的。
