摘要
[目的]探讨科学、高效的柴达木枸杞施肥、灌水模式。[研究]以3年生红枸杞为试材，研究了不同水肥组合对柴达木地区枸杞产量的影响。[结果]灌水量对枸杞产量的影响大于施肥量，但是过多的施肥量和灌溉量并不利于枸杞产量的增加，中肥（607．50 kg／hm2）和中水灌溉施肥（5010．00 m3／hm2）组合为该试验水肥调控的最佳组合，可取得较高的枸杞产量。[结论]为柴达木地区枸杞高产栽培提供了科学依据。
Abstract
Objective] The study aimed to explore the scientific and efficient fertilization and watering mode of chaidamu Lycium chincnse Mill..[ Method] With 3 year old Lycium chincnse Mill.as test materials,the effects of different water and fertilizer combinations on yield of Chinese wolfberry were studied in the chgaidam region.[Result] Effect of irrigation on Lycium chincnse Mill.output is greater than the amount of fertilizer, but after fertilization and irrigation amount is not conducive to increase the yield of Lycium chincnse Mill., the best combination in fertilizer and water for irrigation and fertilization combination mode of regulation of the test of water and fertilizer , which can obtain high yield of Lycium chincnse Mill..
