栽培植物的经济学产量及其在生物学产量中所占的比重,以及产品的质量等,也与光能的利用有密切关系。因此,研究栽培植物的丰产优质,在很大程度上可以说就是研究如何更好地利用光能的问题。充分利用光能的途径很多,概括起来大体有三个方面:一是通过改变植物本性,如高光效育种;二? Economical production of cultivated plants and their share of biological yield, as well as the quality of products, but also with the use of light energy are closely related. Therefore, studying the high yield and quality of cultivated plants can be said to be largely a matter of studying how to make better use of light energy. There are many ways to make full use of light energy, generally speaking, there are three aspects: First, by changing the nature of plants, such as high light efficiency breeding;
