The utility model discloses sapling cultivation equipment which comprises a cultivation box, a cultivation table is arranged on the inner wall of the bottom of the cultivation box, a plurality of cultivation grooves distributed at equal intervals are formed in the top of the cultivation table, a water tank is arranged on one side of the cultivation box, and a water suction pump is arranged on the top of the water tank. A water pipe is arranged at the output end of the water pump, a water spraying pipe is arranged at the end, away from the water pump, of the water pipe and fixed to the inner wall of the top of the cultivation box, a plurality of atomizing nozzles distributed at equal intervals are arranged on the surface of the water spraying pipe, and an irradiation opening is formed in the end, away from the water tank, of the cultivation box; an overturning plate is hinged to the inner wall of the bottom of the irradiation opening, the overturning plate is of an L-shaped structure, and the overturning plate is connected with the cultivation box through a locking mechanism; the cultivation box can preserve heat in the cultivation box, the cultivation effect is good, and the situation that seedlings are frozen to death due to the fact that the temperature is too low is avoided.

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.

The invention discloses a windproof and heat-insulating device for pitaya planting, and specifically relates to the field of pitaya planting. The device comprises a planting shed body, a windproof component is arranged on the surface of the planting shed body, a heat-insulating device is arranged inside the planting shed body, closed shed boards are arranged at both ends of the planting shed body, and inlet and outlet slots are opened on the closed shed boards, the windproof component comprises a closed film layer, a winding motor, a winding component, a cleaning component, a scraping component, a double-sided toothed chain belt and a linkage component, one end of the closed film layer close to the land along the direction of the shed can be detachably mounted on the winding component, two winding motors are arranged and symmetrically fixed on extension brackets at both ends of the planting shed body, the invention effectively prevents wind by arranging the closed film layer, and pitaya is planted in the windproof shed to prevent wind, while effectively solving the problem of heat preservation, avoiding freezing to death of pitaya seedlings due to large temperature difference, and improving the planting survival rate.
