Description
Technical Field

The planting environment data in the medicinal material planting process has important significance in the aspects of improving quality and yield of medicinal materials and the like, for example, excessive humidity easily causes plant diseases and insect pests to breed, increases the risk of diseases of the medicinal materials, and the excessive low humidity can enable the water evaporation of the medicinal materials to be too fast, so that leaf withering and growth limitation are caused. Therefore, in the process of planting medicinal materials, ventilation measures in the planting shed need to be monitored and regulated in time so as to ensure the healthy growth state of the medicinal materials. In addition, due to the variability of the planting environment of the medicinal materials, the medicinal materials in the planting shed have growth variability, so that the demand of each subarea in the shed for ingredients is different, and in order to ensure that the medicinal materials in each subarea can be supplied with proper nutrient, the specific analysis of the fertilizer proportioning is required.
At present, the existing environment data in the medicinal material planting shed can only be monitored, and abnormal conditions cannot be responded and processed in time, namely, an automatic ventilation management mode is lacked. For example, when detecting that the temperature is too high, the system needs to take measures to adjust the ventilation mode rapidly to reduce the temperature, however, the current monitoring mode cannot respond immediately, and manual intervention is needed, so that the treatment time is delayed and the stability of the growing environment of the medicinal material is affected.
On the other hand, the conventional fertilization and irrigation mode in the medicinal material planting shed is focused on global unified management, namely, fertilizers with the same proportion are applied to all areas in the shed, so that the specific nutrient requirements of different areas in the medicinal material growing process cannot be met. Some localized areas may require more fertilizer to meet their growth needs, and current approaches fail to achieve such fine tuning.
