植株生长形态与环境监测系统的研究

针对植株生长形态与种植环境间的实时生长过程监测问题,本文以番茄生长过程为例,采用多传感器信息融合数据采集技术,研发植株生长形态与种植环境实时监测系统,在此基础上分析番茄生长形态参数与种植环境间的对应关系。研究结果表明,番茄生育的不同阶段对水分的需求也不同,因此应分段进行管理,在番茄苗期,土壤湿度对番茄生长的影响较为显著,通过对比实验发现,当土壤相对湿度保持在65%~85%的情况下,既有利于番茄幼苗成长,又有利于番茄开花结果。因此番茄幼苗期的灌溉水以每5~6d浇水1次为宜;但在番茄结果期,每株番茄每天则多浇1L水,使其能够保持足够的土壤湿度条件。通过系统研发及应用,该研究可进一步实现植株生长过程中的精准作业,为物联网技术在农业生产上的推广应用打下基础。

Research and Development of Plant Growth Configuration ＆ Cultivation Environment Monitoring System

Real and dynamic plant growth configuration ＆ cultivation environment monitoring plays an important role in the aspect of analyzing the dynamic relationship between plant growth trend and cultivation environment.In this article,by taking tomato as an example,plant growth configuration ＆ cultivation environment monitoring system was developed based on multi-sensors overlapping technology.The results show that soil humidity＇s influence to tomato growth is obvious.In addition,irrigating water requirement is different during the whole process of plant production.Thus,plants needed to be handled by dividing them into different stages.When the value span of the relate soil humidity is changed from 65 percent to 85 percent,the tomato＇s cultivation performance is better.Thus,the irrigated water interval in the seedling stage will be five or six days.However,the irrigating water should be irrigated more than 1L per tomato in the fruit level to make the soil can keep a reasonable soil humidity level.By actual application of this system,the precise agriculture can be realized.
