| 摘 要： | 1 Introduction Sodium alginate and chitosan are the oceanic natural resources and high molecular com-pound which can promote the plant growth,and protect various plants from harmful organ-isms or prevent plant disease caused by harmful organisms( Makuuch,1 998and Hadwiger,etal. 1 983) .The two materials were used as coating materials,plant promoters,foliar sprayingin soil and so on( Mitchell,1 96 2 ;Brown,982 ;Cuero,1 991 ,Osuji,1 992 ) .Because the two ma-terials are degradable in soil …

| Abstract: | Seeu coating can make soybean seedling grow more strongly and reinforce the resistance of soybean plant. Sodium alginate and chitosan are high-molecular compound of two different kind,have the characteristic of promoting the crop growth. Using Sodium alginate and chitosan as coating materials under different concentration can improve the growth and photosynthesis obviously and can decrease pollution because of their characteristics. The analysis show that the effects of Sodium Alginate on soybean plant are better than chitosan and the best concentration is 0.50 g @ kg-1 |
