采用田间小区试验,研究了不同有机无机肥配施对莴苣的光合作用、产量与品质的影响。结果表明:有机无机肥配施能够增加莴苣的叶绿素含量,增强莴苣的光合作用,促进莴苣产量和品质提高;其中,化肥配施生猪养殖垫料和稻草加菌剂堆制发酵的有机肥C(处理C)的增产效果最好,比纯化肥处理增产25.15%;化肥配施生猪养殖垫料堆制发酵的有机肥A(处理A)的莴苣品质最好。
Field experiments were conducted to study the effects of different organic and inorganic fertilizers on photosynthesis, yield and quality of lettuce. The results showed that organic-inorganic fertilizers could increase the chlorophyll content of lettuce, enhance the photosynthesis of lettuce, and promote the yield and quality of lettuce. Among them, the organic fertilizer C The yield of treatment C) was the best, which was 25.15% higher than that of pure fertilizer treatment. The lettuce quality of the organic fertilizer A (treatment A) with fertilizer combined with pig litter was the best.
