| It is clear that through three years' systemic study on key factor of affecting high quality of sugar beet (different planting pattern, fertilizing and test of disease and pest preventing): planting sugar beet with paper-pot breeding and two ridge can get the highest quantity, output per hectare can get 55660.5kg,sugar content can get 17.4%. The result of fertilizing is that the most efficiency ratio of N: P: K is l:0.72:0.26,the average output per hectare is 38986.5kg; the sugar content can get 17.15%. Several test of preventing for seedling head disease and pest of sugar beet had been done ,the result is that 30% thiram and carbofuran seeding chemical can get most efficiency control to Fusarium oxysporium chelcht of sugar beet, the average preventing effect can get 80.7%, the average preventing effect to pest in soil can get 95%, to flea beetle can get 89.8%,the increasing of sugar content is 1.5% ,the increasing of output is 25 %. |
