摘  要
 随着社会的发展科学技术的进步，人们的对自然界的认知也越来越深入。生物学家发现当给植物播放适当的音乐是植物的生长速度会发生改变，为了能更好的促使农作物的生长，专业人士提出给农作物播放合适的音乐，这样对于以农作物为主要经济来源的农民而言，农作物的生长周期变短，代表着这一部分农民的投资周期也将变短，生活质量也将上升。本次设计主要是为了完成这项测试而提出的。
 本次设计是在单片机的基础上进行设计的，主要用于音乐模块DMA5061的控制，再直接通过音箱播放音乐。对于单片机而言主要使用了EUSART异步通信功能和定时作用，设计过程中主要使用PROTEL绘制原理图和PCB板，再使用MAPLAB编程。
关键词：单片机、音乐、异步通信、编程

Abstract
      With the social development of scientific and technological progress，people's awareness of the natural world more deeply. To plant biologists found that when music is playing an appropriate plant growth rate change, in order to better promote the growth of crops, professional players crops suitable to the music, for such crops as the main source of income of farmers, the crop growth cycle shorter, representing the farmers of this part of the investment cycle will be shorter, the quality of life will also be increased. The design is to complete the test proposed.
      The design is based on single-chip design, mainly used for music control module DMA5061, And then play the music directly through the speakers. The main use for the purposes of a single-chip asynchronous communication functions and EUSART regular role in the design process using PROTEL drawing schematic and PCB board, re-use MAPLAB programming.
Keywords: Single-chip, music, asynchronous communication, programming
