Abstract


2008-2009 at the Beijing Institute of Animal Husbandry and Veterinary , as to the alfalfa and Mengnong sainfoin material , a combination of field trials and indoor physiological and biochemical tests , research in the Beijing region fertilization and line spacing of alfalfa and Mongolia farming sainfoin seed production and quality impact , the results showed that : 1 . production line spacing of the alfalfa and Mengnong sainfoin seed has a significant impact ( P lt; 0.05 ) . Alfalfa seed yield than row spacing 70cm row spacing of 50 cm and 90 cm handle increased 20.8% and 24.4% , respectively . The sainfoin Mengnong highest seed yield of row spacing 50cm 1216 kg/hm2, than 90cm processing a significant increase of 57.25% . Line spacing of the alfalfa and Mengnong sainfoin seed quality was not significant (P gt; 0.05). 2 spring full facilities test , phosphate 50 kg/hm2 highest seed yield of alfalfa , significantly increased 28.3 % ( P lt; 0.5 ) compared with the control ; processing the seed of the relative conductivity of the liquid , soluble sugar content and MDA minimum . Autumn / spring ( 1 / 1 ) and autumn / spring ( 1 / 2 ) test , P fertilizer 100 kg/hm2 alfalfa seed yield were the highest , respectively, compared with the control was significantly higher than the 33.1% and 36.7% (P lt; 0.5 ). Autumn / spring ( 1 / 1 ) trial , 100 kg/hm2 processing phosphate fertilizer significantly reduced seed leaching solution of soluble sugar content and malondialdehyde . Autumn / spring ( 1 / 2 ) test , the phosphate fertilizer 100 kg/hm2 processing seed MDA than the control significantly reduce the 23% . Three modes of applying potassium fertilizer applying potassium fertilizer were significantly reduced alfalfa seed yield and the content of MDA ( P lt; 0.05 ) . Consider the economic benefits , alfalfa seed fields can be less or not potassium fertilizer . Three modes of P fertilizer , phosphate fertilizer 100 kg/hm2 processing Mengnong sainfoin seed yields are at their highest , while the seed lixivium relative conductivity minimum . P fertilizer significantly reduced Mengnong sainfoin seed MDA content ( P lt; 0.05 ) . From seed production , in terms of P fertilizer can increase seed yield Mengnong sainfoin . 5 Three kinds of potassium mode , the potash seed yield of sainfoin Mengnong does not significantly (P gt ; 0.05) , but significantly reduced the relative conductivity of the seed solution , soluble sugar content , and the content of MDA . Visible , Fertilization on the Mengnong sainfoin seed did not increase yield , seed quality improvement .
