Embodiment 1
[0060] Chinese cabbage at the seedling stage is used as an experimental crop, and the system provided by the invention is used to solve the problem of automatic fertilization of Chinese cabbage when the temperature difference is too large. The system includes a temperature detection module, a central analysis control module and an automatic fertilization module;
[0061] The temperature detection module includes temperature detection equipment to measure the temperature data of the environment where the crops are located;
[0062] The central analysis control module includes a temperature analysis module, an operation module, and an input module, and the input module is connected to the temperature analysis module and the operation module;
[0063] The temperature analysis module receives temperature data for analysis and temperature difference classification, and outputs the temperature difference level to the calculation module;
[0064] The operation module is provided with...
Embodiment 2
[0079] Taking cucumbers at the seedling stage as experimental crops, the system provided by the invention is used to solve the problem of automatic fertilization of cucumbers under excessive temperature differences. The system includes a temperature detection module, a central analysis control module and an automatic fertilization module;
[0080] The suitable average daytime temperature for cucumber at the seedling stage is 30°C, and the suitable nighttime average temperature is 15°C;
[0081] The temperature sensor in the temperature detector detects that the current maximum temperature during the day is 18°C, and the minimum temperature at night is 11°C; by daily maximum temperature - daily minimum temperature - crop suitable temperature difference = 3K ~ 3 (K + 1), that is, 18-11- (30-15)=3K~3(K+1), confirm K=-2,
[0082] Input soil moisture H=75% in the input module, input crop related information P=cucumber, seedling stage, crop area 5 mus and temperature difference leve...

Abstract
The invention provides an automatic fertilizing system for solving crop problem of overlarge temperature difference. The automatic fertilizing system comprises a temperature detection module, a central analysis control module and an automatic fertilizing module, an operation method in the central analysis control module is to establish a relation formula between temperature difference grade and fertilizing information data, and the formula is shown as follows. With overlarge temperature difference, automatic fertilizing is performed to compensate deficiency of nutritional elements in the crop growing process, manpower cost is saved, temperature conditions are detected automatically, and automatic fertilizing is realized; growing development and morphogenesis of crops can be adjusted automatically, culture period can be shortened, quality can be improved, energy consumption can be reduced greatly, and cost can be lowered.
Description
technical field [0001] The invention relates to the field of crop fertilization, in particular to an automatic fertilization system, equipment and method for solving the problem of crops under excessive temperature difference. Background technique [0002] Temperature is one of the important conditions for plant growth, and temperature is an important signal for plant growth, flowering and fruiting. The growth and development of the physiological activities of plants must be carried out within a certain temperature range. When the temperature is lower or higher than the temperature range that the plants can tolerate, the growth will gradually slow down and stop, the development will be hindered, and the plants will suffer or even die. The photosynthetic organs of crops are extremely sensitive to temperature, and the temperature difference between day and night can regulate the functions of photosynthetic organs. As a probe for crop photosynthesis research, chlorophyll fluo...
