3results about How to "Improve sunlight utilization" patented technology

The present application relates to organic solid waste resource utilization and processing technical field, especially be a kind of slot type aerobic fermentation roof that is convenient to open and close, the present application is integrated with five big functions of light, rainproof, heat preservation, deodorization, ventilation by top double-layer function layer, without additional heat preservation shed, deodorization tower and other equipment, and by independent or linkage adjusting the opening and closing state of nanometer membrane layer, sunlight shed layer, it can adapt to sunny, rainy, low temperature, high temperature and different air, as well as the demand of different fermentation stages such as temperature rising period, high temperature period, decomposition period, solve the problem of traditional device single function, poor adaptability, improve the sunlight utilization rate of temperature rising period by sunlight shed, accelerate temperature rising, while the air sandwich layer between the closed state of double-layer sunlight shed can effectively heat preservation, avoid temperature loss too fast in winter, the blocking rate of odor molecules reaches more than 90% using nanometer membrane layer, without setting deodorization equipment separately, greatly reduce operating cost.

This invention provides a method for planting multiple crops of fast-growing crops per year with alternating periods of vigorous growth and seedling stage. The method includes soil improvement in the planting area to ensure that the organic matter content in the soil is greater than or equal to a preset value, eliminating the need for tilling for two years; dividing the planting area into a first zone and a second zone, with a wheeled or tracked path between them; inhibiting crop growth in the first or second zone to alternate between vigorous growth and seedling stage crops; and applying fertilizer to the first or second zone, specifically in the following situations: applying fertilizer to the first or second zone after harvest; and / or applying fertilizer to the first or second zone during the seedling stage. This invention achieves alternating periods of vigorous growth and seedling stage crops on the same land by inhibiting crop growth in the first or second zone, thereby improving sunlight utilization. Furthermore, the wheeled or tracked path prevents damage to the root system during the vigorous growth or seedling stage.

The utility model belongs to the technical field of photovoltaic power generation panels, and discloses an angle-adjustable photovoltaic power generation panel, which comprises a bottom plate, a photovoltaic support is movably connected to the middle of the top end of the bottom plate, a movable shaft is movably sleeved with the top end of the photovoltaic support, a connecting block is fixedly sleeved with the outer surface of the movable shaft, and the angle-adjustable photovoltaic power generation panel is arranged on the bottom plate. The outer surface of the connecting block is movably connected with the inner surface of the top end of the photovoltaic support. Through the arrangement of the driving motor, the lead screw, the movable plate, the cylindrical block and the rotating rod, when the driving motor operates, the lead screw rotates to drive the movable plate to move forwards, and then the cylindrical block moves forwards to drive the rotating rod to rotate with the movable shaft as the axis, so that the photovoltaic power generation panel is driven to rotate with the movable shaft as the axis; the purpose of adjusting the angle of the photovoltaic power generation panel is achieved, the problem that the angle of the photovoltaic power generation panel is inconvenient to adjust is solved, and the sunlight utilization rate of the photovoltaic power generation panel is increased.
