生物补光在树莓反季栽培过程中对其营养生长的影响

摘要

为解决北方地区树莓反季栽培过程中光照不足的问题，利用植物生长灯补充照射的方法，设置补光又施肥、只补光不施肥、不补光不施肥3个处理，研究生物补光对树莓营养生长的影响。结果表明：经施肥和植物补光灯照射后树莓的营养生长明显高于不施肥和不补光的，同时也高于不施肥和补光的处理。北方地区树莓反击栽培过程中合理补光有益于促进树莓的营养生长进而也会提高后期的产量。%In order to solve the promble of the infufficient light in anti seasom cultivation of raspberry ,through the method of adding plant grow th lamp irradiation ,three treatments were conducted to study the effect of bio‐logical light on the nutrition growth of raspberry including both fill and fertilization ,only fill without fertiliza‐tion and fill without fertilization .The results showed that after fertilization and filling light irradiation ,rasp‐berry nutrient growth was significantly higher than no fertilizer and no lighting ,but also higher than CK and filling light .In short ,reasonable filling light was beneficial to promot raspberry vegetative growth and im‐proved late excess for northern raspberry anti season cultivation .
