为了更好地满足城市居民对阳台蔬菜栽培架的需求,在分析研究阳台农业及相关技术的基础上,通过阅读相关文献及大量蔬菜种植试验,得到了栽培架影响蔬菜生长发育的三种关键性因素。以生菜为试验对象,选取定植篮深度、间隔时间以及循环时间为影响因素,以生菜叶单位时间内平均生长长度为指标,进行种植试验。通过正交试验的方法并借助SPSS软件进行数据分析,得到了三种关键性因素的最优组合,即当采用50 mm深的定植篮,间隔1.5 h,循环20 min时,生菜叶在单位时间内平均生长长度最大。该研究结果可为无土栽培领域自动控制循环系统的研制与开发提供参考。
In order to better meet the urban residents on the balcony of vegetable cultivation shelves on the basis of the analysis of the balcony of agriculture and related technologies, based on reading the relevant literature and a large number of vegetable cultivation experiments, the cultivation of three kinds of vegetables are affected the growth and development of the key factor. Taking lettuce as the test object, we selected the depth of planting basket, the interval time and the cycle time as the influencing factors, and took the average growth length of lettuce leaf as the index for the planting experiment. Through orthogonal experiment and data analysis with SPSS software, the optimal combination of the three key factors was obtained. When using a 50 mm deep planting basket with an interval of 1.5 h and cycling for 20 min, Within the average growth length of the largest. The results of this study can provide reference for the research and development of automatic control circulatory system in the field of soilless culture.
