摘要： 为了推动草业的大力发展，提高苜蓿草产量和质量，增加种植苜蓿的效益，笔者进行了苜蓿生长期喷施叶面肥和植物生长调节剂试验，从供试的5种叶面肥（药）中筛选出了2种适合苜蓿生长的叶面肥。试验证明叶面喷施磷酸二氢钾和澳优对苜蓿具有明显的增产效果，且能显著提高粗蛋白含量、降低粗纤维的含量，其增产效果达20%以上，粗蛋白含量提高9.37%~10.62%、粗纤维的含量降低5.91%~4.36%。因此，在苜蓿生长期推荐使用磷酸二氢钾和澳优进行叶面处理，喷施浓度分别为1000倍和500倍。

Abstract: To adapt to the rapid development of grass industry, improve the yield and quality of alfalfa and increase the benefits of alfalfaplanting, the experiments onfoliar fertilizers and plant growth regulatorswere conducted, 2 suitable foliar fertilizers were screened out from 5. The results showed that the yield of alfalfa increased more than 20% under the treatments of KH2PO4 and Ausnutria, and the crude protein content increased significantly by 9.37%-10.62%, and crude fiber content was reduced by 5.91%-4.36%. As a result, KH2PO4 and Ausnutria were recommended as foliar fertilizers during the growth period of alfalfa with the concentration of 1000 times and 500 times.
