增甘膦提高甜菜含糖效应的研究

增甘膦具有抑制甜菜叶部生长、促进根部生长和增加蔗糖含量的作用,并能减少还原糖和非糖物质。试验表明,于甜菜收获前30—40天,用0.2—0.3％浓度,每亩叶面喷施50—100克增甘膦,能提高含糖率1.2—2.5％。生产示范证明,用0.2％浓度,每亩甜菜喷施50克增甘膦,能提高含糖率0.4—1.6％。

STUDIES OF AMINOPHOSPHONATE ON THE EFFECT OF INCREASING SUCROSE CONTENT IN SUGAR BEET

The studies showed that aminophosphonate retarded foliage growth,enhanced root growth and raised sucrose content but decreased reducing sugarand non-sugar substances in the root of sugar beet.Treatments with 50 to 100grams of aminophosphonate per mu,in 0.2—0.3%of concentration,used 30 to 40 days preharvest as foliage spraying caused anincrease of 1.2—2.5% of sucrose content.Demonstration production showedthat 50 grams of aminophosphonate per mu and 0.5% of concentration increased0.4—1.6% of sucrose content.
