阳台蔬菜栽培架对蔬菜生长影响因素的试验

The inquiry experimental of the key factors affecting growth of balcony vegetable cultivation shelf

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 satisfy the needs of planting on the balcony for urban residents, on the basis of analysis of the balcony of agriculture and related technologies, through reading related literatures and a large number of vegetable cultivation test, ob- tained three factors that influence the growth and development of vegetables. Regarding the lettuce as test subjects, selecting the depth of the planting basket, interval time and cycle time as the factors. Regarding the average growth of length of lettuce in unit time as the index, making planting experiments. Through the method of orthogonal experiment and the SPSS software, this article has found the best combination of the three factors which could influence the growth of the vegetables. Which us- ing the 50 rnm deep planting basket, interval 1.5 h and 15 rain respectively could get the maximum length of lettuce in unit time. The study results can provide a reference for research and development in the field of automatic control loop soilless cultivation system.
