Abstract:
Shading durat ion had some ef fect on the yield and quality of soybean through analysis.Along w iththe increase of shading duration , and the decrease of sunshine duration , the content of pro tein w as rising .Whenthe sunshine duration w as 12 hours , the content of protein reached the maximum value , and then dropped .Thisverified the previous view points of sho rt -time sunshine helpful to the fo rming of the protein .The changes of fatcontent w ere opposite to that of the pro tein .With the shortening of the sunshine duration , the fat content decreased.This show ed that the content of pro tein and fat had the negative correlation .The circumstance that wasadvantageous to the forming of the pro tein w as disadvantageous to the forming of the fat .Wi th the increasing ofthe shading duration and the shortening of the sunshine hours , the plant height , the number of pods and seedsper pod decreased w hich made the yield of soybean dropped .The order of shading on the yield and quality ofsoybean w as y ield (F =5 .93＊＊)> the content of protein (F =3 .16＊)>the content of fat (F =2 .61)>the totalcontent of protein and fat (F =0 .64).
