研究了红光、蓝光(8∶1)组合的LED灯补光对日光温室栽培杏产量及品质的影响,结果表明,补光处理后金太阳、凯特杏单株开花数、坐果率、单果重、单株结果数、单株产量、果实纵径、果实横径,以及可溶性固形物、维生素C含量均明显高于不补光处理。该LED灯补光方法在甘肃省定西地区杏树反季节栽培中提高杏产量、改善果实品质效果明显。
The effects of supplemental red light and blue light (8:1) on the yield and quality of cultivated apricot in solar greenhouse were studied. The results showed that the number of flowers per plant, fruit setting rate, fruit weight per plant , The number of fruit per plant, the yield per plant, the longitudinal diameter of fruit, the diameter of fruit, the content of soluble solids and vitamin C were significantly higher than those of non-supplemented light. The method of supplementing LED lamp can improve the yield of apricot in the season cultivation of apricot in Dingxi of Gansu Province, and the effect of improving the quality of the fruit is obvious.
