This invention provides a method for calculating the optimal time for rolling up greenhouse curtains. The method includes the following steps: calculating the solar altitude angle h for a given region, date, and time; obtaining the temperature equilibrium time point inside the greenhouse during winter; calculating the solar altitude angle h of the temperature equilibrium point inside the greenhouse on different dates during winter; and calculating the optimal curtain-rolling time T for different dates in the given region during winter. The method provided by this invention has the advantage of being able to calculate the optimal curtain-rolling time for greenhouses on different dates and in different geographical locations during winter without relying on complex sensors inside the greenhouse, by integrating geographical information, astronomical parameters, and historical observation data. This improves the utilization of climate resources and effectively mitigates meteorological disasters in facility agriculture.

The application discloses a soil humidity threshold regulation method for efficient cultivation of red plum apricot, and relates to the technical field of soil humidity threshold regulation. The method comprises the following steps: acquiring soil type, root distribution depth and climate conditions, combining a preset red plum apricot growth stage database, determining soil water retention capacity and initial water use efficiency, classifying growth stages by using a k-means clustering algorithm, and acquiring initial humidity thresholds matched with soil and climate. If the climate condition deviation exceeds a threshold value, the humidity threshold value is adjusted by using a linear regression algorithm to ensure adaptation to dynamic environmental changes. Based on the adjusted humidity threshold value and root distribution, a decision tree algorithm is used to evaluate waterlogging risk, a dynamic drainage scheme is generated in combination with a drainage strategy database, and finally the irrigation amount is adjusted in real time by using a proportional-integral-derivative algorithm. The application can dynamically optimize irrigation and drainage strategies, realize precise water management, improve the growth efficiency of red plum apricot, and reduce waterlogging risk.

This utility model belongs to the field of sheepfold technology, and in particular to a sheepfold with a disc-lock steel structure main body. It includes a sheepfold main body composed of a disc-lock steel frame and an outer panel. The side wall of the sheepfold main body has a first heat dissipation vent. It also includes a controller, a temperature sensor installed inside the sheepfold main body for monitoring the internal temperature, a second heat dissipation vent on the top of the sheepfold main body, and an auxiliary exhaust assembly on the top of the sheepfold main body. A gate assembly is provided on the sheepfold main body to control the opening and closing of the first and second heat dissipation vents. The signal output terminal of the controller outputs a control signal, which controls the operation of the auxiliary exhaust assembly and the gate assembly. By adding a second heat dissipation vent to the top of the sheepfold, based on the existing side wall air inlet, and combining it with an intelligent temperature control system, an electric gate assembly, and an auxiliary exhaust assembly, more precise and efficient ventilation and heat dissipation management is achieved.

This utility model discloses a cultivation device for tissue culture seedlings, belonging to the technical field of cultivation devices. The device further includes an upper box body snapped onto the upper side of a base box; a second water pump is fixedly connected to the right side of the base box; a first water pump is fixedly connected to the right side of the upper box body; a water pipe is fixedly connected to the right side of the first water pump; a water tank is disposed on the outside of the base box; the second water pump and the water pipe are connected to the water tank; an atomizing nozzle is fixedly connected to the left side of the first water pump; a pair of sealing plugs are embedded on the front and rear sides of the upper box body respectively; by setting gauze mesh and ventilation holes, the air permeability of the tissue culture seedling roots is improved. Simultaneously, the gauze mesh prevents the soil and moisture in the soil from diffusing outwards, allowing a large amount of water to flow out from the mesh plate. The gauze mesh only absorbs a portion of the water and becomes moist, which is beneficial for the rapid growth of the tissue culture seedling roots. At the same time, the sealing plugs allow the tissue culture seedling leaves to come into contact with the air, facilitating control of the air exchange time between the inside of the upper box and the outside environment, thus improving cultivation efficiency.

The present application relates to the technical field of sapling cultivation, in particular to a seedling anti-freezing device for forest cultivation, which comprises a base and a water inlet, the base is hollow and has a water storage function, the outer wall of the base is made of rubber plastic material and has a heat preservation effect, at least two heat exchange mechanisms are installed on the upper surface of the base at equal intervals in the circumferential direction, the heat exchange mechanisms extract water from the air to supplement the saplings, a supporting mechanism is installed between the heat exchange mechanisms, the bottom of the supporting mechanism is fixed to the base, the supporting mechanism supports the plastic cloth and prevents the saplings from freezing. The device effectively breaks the low-temperature-induced dormancy mechanism of the sapling root system, prevents the sapling rhizome from freezing injury and death, provides a suitable temperature environment for root development, effectively avoids soil water evaporation, continuously ensures soil moisture, promotes the growth and development of the sapling root system, and thus shortens the tree maturation period. The device can increase the light concentration to increase the temperature and avoid low temperature from inhibiting the growth of the saplings, or can reduce the light concentration to reduce the temperature and prevent high temperature from burning the saplings.

This invention relates to the field of intelligent feeding technology for livestock and poultry farming, and in particular to a method and system for precise automatic feeding of pigs based on electroencephalogram (EEG) analysis. The method includes: acquiring raw EEG signals of pigs in different states in real time using a wearable EEG acquisition device; preprocessing and extracting features from the raw EEG signals, and inputting the processed feature data into a hunger state recognition model for identification; when the identification result indicates a hunger state, sending a feeding command to the corresponding pigpen feeder, which then feeds the pig according to a preset basic feeding amount; and dynamically adjusting feeding parameters based on the feeding feedback after feeding to achieve closed-loop precision feeding. This invention significantly reduces feed waste and labor costs in livestock farming.
