3results about How to "Prevent root rot" patented technology

The utility model relates to the technical field of seedling raising devices, in particular to a seedling raising device for rice planting, which comprises a rotating disc, a sprinkler pipe, a light shield, a seedling raising box and an adjustable seedling raising hopper, through the design that the rotary sprinkling pipe is matched with multiple groups of spray pipes, uniform sprinkling of a water and fertilizer solution in the seedling raising box is realized, the problem of uneven dryness and humidity caused by traditional manual watering is avoided, root rot or local drought is effectively prevented, and the germination rate and the seedling uniformity are improved; the adjustable seedling raising hopper driven by an air cylinder is adopted, the seedling raising depth can be flexibly adjusted according to the root system requirements of different rice varieties, the root system growth environment is optimized, the transplanting survival rate is increased, the light shield is provided with an adjustable light source, the seedling raising state is monitored in combination with an infrared laser, precise light supplementing or shading is achieved, and the illumination requirements of different growth stages are met; healthy growth of seedlings is promoted, and the overall seedling raising effect is improved.

This utility model discloses a Codonopsis pilosula seedling transplanting and cultivation rack, including a seedling planting box. A frame supports the top of the seedling planting box, and the frame supports multiple seedling planting containers. Each seedling planting container has multiple through-hole structures. One end of the seedling planting box has a water supply pipe, and the end of the seedling planting box away from the water supply pipe has a drainage structure to control the water level inside the seedling planting box. The bottom of each seedling planting container has a threaded material cover structure with a drainage outlet. The advantages of this utility model compared to existing technologies are: this utility model, through a single detachable seedling planting container, facilitates individual seedling cultivation and transplanting operations. Simultaneously, the water supply pipes and drainage structures on both sides of the seedling planting box facilitate control of the seedling water level, ensuring seedling cultivation while preventing root rot caused by excessive water.

The utility model provides a device capable of preventing a culture medium from being polluted. The device capable of avoiding culture medium pollution comprises a planting box used for storing a culture medium; the supporting plate is fixed on the outer wall of the planting box; the connecting plate is placed on the supporting plate; the supporting rod is mounted on the connecting plate; the protective net covers the supporting rods and is used for isolating pests and pollution impurities, and an isolation net used for expanding the coverage range of the protective net is sewn on the protective net. According to the device capable of preventing the culture medium from being polluted, through the arrangement of the protective net, the isolation net and the transparent thin film, pests, pollution impurities and natural rainwater are effectively isolated, the culture medium and gastrodia elata are protected in an all-around mode, and the pollution risk is reduced.
