目前,海带(Laminaria japonica Aresch)养殖的主要问题在于产量和貭量的提高。影响海带产量和质量的因素很多,有环境的因素,又有遗传的因素。如何区别环境和遗传的影响,如何控制环境和遗传,以提高海带的产量和貭量,是海带养殖研究的主要课题之一。 叶片是光合作用的主要器官。农作物产量的高低在很大程度上受叶片总面积的制约 Currently, the major problem with the culture of Laminaria japonica Aresch is the increase in yield and yield. Many factors affect the yield and quality of kelp, environmental factors, but also genetic factors. How to distinguish between environmental and genetic effects, how to control the environment and heredity in order to improve the yield and quantity of kelp, kelp farming is one of the major topics of research. The leaves are the main organs of photosynthesis. The level of crop yield is largely governed by the total leaf area
