棉花的经济产量和生物产量,都是其绿色部分利用光能把水和二氧化碳合成的有机物,在棉花生长发育过程中,如苗期、蕾期、花铃期等不同生长发育时期,都要求有适宜的光照强度,现将光照强度与棉花三桃消长规律分析整理如下:一、光照强度与单株成铃和蕾铃脱落的关系在一定范围内光照强度不同,光合产物有高低之分,因此,单株成铃有多少不同的显著差别,据1979和1980年在德州市郊区簸箕刘等大队测验,棉花单株成铃多少和脱落率同光照强度密切相关,如表1.表1指出:光照强度由强到弱,单株成 Both the economic yield and the biological yield of cotton are the organic compounds whose green part synthesizes water and carbon dioxide by using light energy. During the growth and development of cotton, such as seedling stage, budding stage and flower-boll stage, they all require Suitable light intensity, now the light intensity and the growth and decline of cotton three peach analyzed as follows: First, the light intensity and the relationship between boll and boll fall off within a certain range of light intensity is different, the photosynthetic products are high and low points, so , How many different bolls per plant is significantly different, according to 1979 and 1980 in Texas suburbs Dust Pan Liu and other brigade test cotton bolls per plant and shedding rate is closely related with the light intensity, as shown in Table 1. Table 1 states: Light intensity from strong to weak, single plant
