摘要
果树为多年生植物,由于果园土壤不会被经常翻耕,所以易发生盐碱化进而危害果树生长.为了满足精细农业对果园土壤盐碱度长期观测的需求,解决土壤盐碱度采样测量周期长、费用高的缺点,笔者研发了一套果园土壤盐碱度在线监测系统.该系统使用太阳能+锂电池供电,采用485总线接口的免维护数字传感器,可长期布置在果园内进行土壤温湿度和盐碱度数据的多点采集.采集数据既可存储至本地SD卡,又可通过4G网络实时远程传输至云服务器.系统于2019年4月投入使用,截至2021年4月,在无人值守和免维护的情况下一直稳定运行,采集到5个监测点4万多条土壤盐碱度数据,可用于长期实时监测果园土壤盐碱度的变化状况,以便于针对性地采取土壤改良措施.
Fruit trees are perennial plants,and the orchard soil will be infrequently ploughed,so it is more prone to salinization,which will endanger the growth of fruit trees.To solve the problem of long sampling period and high cost of soil salinity measurement,an online monitoring system for soil salinity and alkalinity in orchards was developed.This system uses solar energy+lithium battery for power supply and maintenance-free digital sensor with 485 bus interface,which can be arranged in orchards for a long time to collect soil temperature,humidity and salinity data.The collected data can be stored in the local SD card and transmitted to cloud server in real time through 4G network.Up to now,the system has been running stably for nearly two years under the condition of unattended and maintenance free.More than 40000 soil salinity data have been collected from 5 monitoring points,which can be used for long-term observation of the interaction between salinity and fruit tree growth,in order to take corresponding measures.
