蚯蚓生物制剂对小麦幼苗生理代谢和生长的影响

THE INFLUENCE OF AN EARTHWORM BIOLOGICAL PREPARATIONON THE PHYSIOLOGICAL METABOLISM AND GROWTH OF WHEAT

蚯蚓生物制剂对小麦生理代谢和生长的影响研究表明，在小麦种子萌发期，过氧化氢酶、酸性磷酸酯酶活性和三磷酸腺苷含量分别比对照提高１１９．１％、１１．４％和３７．５％。在小麦幼苗时期，硝酸还原酶活性和幼苗吸收磷的能力分别比对照提高９８．６％和２８．２％。在小麦发芽期，种子活力指数比对照提高２８．９％。小麦三叶期苗高、根长和干重分别比对照提高１３．２％，１９．２％和２４．１％。

Presowing soaking of wheat seeds with an earthworm biological preparation developed bySouthwest Agricultural University increased the activity of catalase and acid-phosphoesterase andATP content by 119.1%, 11.4%and 37.5%,respectively,as compared to the control during seedgermination. In the seedling stage,nitrate reductase activity of the seedlings and their phosphateabsorption ability were 9 8.6%and 2 8.2%higher than the control.Seed activity indexwasenhanced by 28.9%at germination and seedling height,root length and Seedling dry weight at the3-leaf stage were raised by 13.2%,19.2%and 24.1%,respectively,by the treatment.
