Abstract:
In order to explore the suitable light conditions of Apostichopus japonicus in indoor culture, 1680 juvenile sea cucumber (weight 0.185±0.014 g) were placed in three irradiance (1 000 mW/m2, 2 500 mW/m2, 4 000 mW/m2) in the environment of red (R)、full spectrum (W) and dark (D) for 35 days. The results showed that different spectra and irradiance could significantly affect the growth and physiological function of juvenile sea cucumber. The body weight of the red light 4 000 mW/m2 group was significantly higher than that of the full spectrum 4000 mW/m2 group (P<0.05). The body length of the red light 1 000 mW/m2 group was significantly higher than that of the full spectrum 4000 mW/m2 group(P<0.05). The specific body weight growth rate of the red light 1000 mW/m2 group was significantly higher than that of the full spectrum 4000 mW/m2 group (P<0.05). The survival rate of the red light 4000 mW/m2 group was significantly higher than that of the full spectrum 4000 mW/m2 group(P<0.05). For enzyme activity, amylase (AMS) activity was the highest in the red light 4000 mW/m2 group and lipase (LPS) activity in the red light 2500 mW/m2 group. The activities of acid phosphatase (ACP) and alkaline phosphatase (AKP) in the red light 4000 mW/m2 group were significantly higher than those in the red light 1000 mW/m2 group (P<0.05). The catalase (CAT) activity was the highest in the full spectrum 2500 mW/m2 group. The activity of superoxide dismutase (SOD) was the highest in the red light 4000 mW/m2 group, which was significantly higher than that in the full spectrum 1000 mW/m2 group(P<0.05). In summary, it is recommended to use red light to cultivate juvenile ginseng in an indoor culture environment and control the irradiance at 1000-4000 mW/m2. In this study, the effects of three irradiance degrees on the juvenile ginseng were studied, and the results showed that the growth performance of the juvenile ginseng with red light of 1000-4000 mW/m2 was better. In order to accurately and optimally determine the most appropriate irradiance, a fine irradiance gradient was recommended to further evaluate the effect of irradiance on the young radiance.

摘要： 为探讨刺参( Apostichopus japonicus)在室内养殖中的适宜光照条件，将1 680只稚参(体质量0.185±0.014 g)分别置于3种辐照度(1 000 mW/m2、2 500 mW/m2、4 000 mW/m2)的红光(R)、全光谱(W)及黑暗(D)的环境中，进行为期35 d的养殖试验。结果显示，不同光谱及辐照度能够显著影响稚参的生长及生理功能。其中红光4 000 mW/m2组体质量和存活率显著高于全光谱4 000 mW/m2组(P < 0.05)；红光1 000 mW/m2组体长显著高于全光谱4 000 mW/m2组(P < 0.05)；红光1 000 mW/m2组体质量特定生长率显著高于全光谱4 000 mW/m2组(P < 0.05)。对于酶活性，红光4 000 mW/m2组淀粉酶(AMS)、酸性磷酸酶(ACP)和超氧化物歧化酶(SOD)活性最高；全光谱2 500 mW/m2组的过氧化氢酶(CAT)活性最高；红光4 000 mW/m2组超氧化物歧化酶(SOD)活性最高；红光4 000 mW/m2碱性磷酸酶(AKP)活性均显著高于红光1 000 mW/m2组(P < 0.05)。综上所述，建议在室内养殖环境中采用红光养殖稚参，并控制辐照度在1 000~4 000 mW/m2。
