主　　题：Studies on high-yielding cultivation of rice in Guangdong by diagnosis and control of chlorophyll content and LAI high 

摘      要：During the 1970’s and 1980’s studies on the rela-tion between LAI and yield had been carried out *** main results were as follows:(1)Usingthe accumulated LAI value at three stages,*** initiation(PI),heading(H)and 20 d afterheading(H),to analyze the relation between LAIand yield was more accurrate than only using theLAI value at H stage(see table);(2)Reaching cer-
