摘要
Abstract
The plant growth and mineral elements content were studied in hydroponically-grown lettuce (Lactuca sativa L.)under five different root zone temperatures.The results showed that with the increase of root zone temperature,the lettuce yield per plant increased first and then decreased,reaching the maximum value at 25 ℃,and the dry matter content was the highest.Effects of root zone temperature on lettuce leaf net photosyn-thetic rate and the content of mineral elements were similar to the yield.Under the treatment of 35 ℃ root zone temperature,the lettuce growth and mineral elements accumulation were significantly inhibited,and the nitrate content decreased significantly.The results indicated that the most suitable root zone temperature was 25 ℃ for the growth and mineral elements absorption of hydroponically-grown lettuce.关键词
