摘要
我国西北地区冬季光照时间短,日光温室内部光照不足,严重影响设施越冬茬蔬菜的生长发育,本试验使用LED植物生长灯对日光温室西葫芦进行补光,以期筛选出西北地区设施越冬茬西葫芦栽培最佳补光时长,为日光温室补光技术的研究和应用提供理论依据。在日光温室条件下,以LED植物生长灯(红蓝7∶2)为补光光源,以不补光为对照,研究不同补光时长(1、2、3 h)对西葫芦生长发育、品质、产量及经济效益的影响。结果表明:与无补光对照相比,补光2、3 h处理显著增加西葫芦果实中维生素C含量、可溶性蛋白含量和糖酸比;补光3 h处理西葫芦的单株结果数、单果质量和产量均显著增加,增幅分别为11.9%、6.8%和11.5%,并且补光3 h处理每667 m^2增加西葫芦经济收入1 307.3元。综上,补光3 h对西葫芦的果实品质改善、产量的提高及农户收入的增加效果最好。
Abstact :The winter sunshine time in northwest China is short, and the light in solar greenhouse is insufficient, which seriously affects the growth and development of winter vegetables. LED lights were used to fill the sunlight of solar greenhouse for planting squash, in order to find out the optimal time for supplemental lighting for cultivation and provide theoretical basis for research and application. Under the normal condition of solar greenhouse, LED plant growth lamps(the ratio of red to blue light is 7∶2)were used as the complementary light source, and different light filling time(1, 2, 3 h)was used to study the growth, quality, yield and economic benefits of squash. The results showed that compared with control (no light replenishing), the treatment of 2 h and 3 h light supplementation significantly increased the vitamin C content, soluble protein content and sugar-to-acid ratio of squash fruits. The number of single plant, single fruit quality and yield of squash increased significantly by 11.99%, 6.8% and 11.5%respectively after supplemented with light for 3 h, and the economic income of squash increased by 1 307.3 yuan per 667 m^2 after light supplementation for 3 h. In conclusion, the supplemental light for 3 h has the maximum effect on the improvement of fruit quality, yield of squash and income.
