| Abstract: In order to clarify the application effect of biological polypeptide on disease resistance, growth and prospect, the application status of biological polypeptide technology were summarized. The existed problems were put forward, which contained that the optimum application concentration of different crops had not been determined, the environmental conditions could affect the application effect of biological polypeptide, the application of biological polypeptide should cooperate with good field management, the sound evaluation system, publicity and promotion of polypeptide technology were lacked. Finally, the application prospects of biological peptides were elaborated. |
