Abstract：Taking 5 garlic varieties,including Leduzi,Japan garlic,Japan rocambole,Xinjiangzi 2,He-beibaigou,as materials,with single plastic film covering as control,the effects of double -layer film covering (plastic film and small arch shed)for 10 days and 20 days in spring on the formation and quality of single -clove garlic were studied,so as to provide references for gaining the high -yielding and good -quality single -clove garlic.The results showed that the plant height,false stem length,false stem diameter,leaf width,leaf length,pigment content,net photosynthetic rate (Pn)significantly increased,and the single -clove rate,sin-gle head weight and the contents of allicin,VC,soluble protein and soluble sugar were higher under double -layer film covering for 10 days.The growth of garlic was harmed by latter higher temperature under double -layer film covering for 20 days.The single -clove rate of Hebeibaigou was 94.63%,85.23% and 80.12%respectively under the double -layer film covering for 10 and 20 days and single plastic film covering,whichwere all higher than those of the other varieties.The single head weight of Hebeibaigou was 6.82,5.92 and5.52 g respectively under 3 treatments,which were only lower than those of Leduzi.The single head weight ofLeduzi was more than 8 g,but its single -clove rate was less than 30%,so it was not suitable for productionof single -clove garlic in spring.Compared with single plastic film covering,the contents of allicin,VC,soluble protein and soluble sugar in bulbs of Hebeibaigou increased by 12.58%,13.22%,4.35% and 6.88%respectively under double -layer film covering for 10 days.In conclusion,the best variety,which was suitablefor producing single -clove garlic in spring,was Hebeibaigou,and the optimum covering date was for 10 dayswith double -layer film.
