Abstract

The invention discloses a cultivating system based on plant nitrogen fertilizer application amount optimization. The system comprises a support. A nutrient solution tank is arranged at the upper portion of the support. A cultivating box is arranged in the middle of the support. A recovery box is arranged at the lower portion of the support. The cultivating box is communicated with the nutrient solution tank through a liquid inlet pipe. The recovery box is communicated with the cultivating box through a liquid outlet pipe. Compost is contained in the cultivating box. An oxygen supply device for injecting oxygen into the cultivating box and a nutrient solution highly-quantitative device are arranged in the cultivating box. The invention further discloses a method based on plant nitrogen fertilizer application amount optimization. The method is simple in structure, simple in operation procedure, low in device cost and convenient to apply and popularize, and meanwhile the experiment time cost is reduced when multiple temperature control cultivating systems are used for experiments.

Description

technical field

[0001] The invention belongs to the technical field of nitrogen fertilizer application research and hydroponic devices, and in particular relates to a cultivation system and method based on plant nitrogen fertilizer application optimization. Background technique

[0002] Precision agriculture is the development trend of modern agriculture, and refined on-demand fertilization is an important part of precision agriculture. At present, most of the fertilization operations in the field are excessively fertilized, resulting in many problems such as environmental pollution and resource waste. The study of on-demand fertilization of plants is of great significance to the development of modern agriculture and the protection of the natural environment. Nitrogen is an important element that constitutes many organic matters in plants. How to accurately determine the amount of nitrogen fertilizer required by plants is of great significance for refined on-demand fertiliza...
