The invention discloses a method for promoting the survival rate and quality of dendrobium indoor cultivation, which comprises the steps of irradiating with red-blue-green mixed light in the bud germination period of dendrobium and using red-blue-green-far-red mixed light in the new bud growth period of dendrobium By irradiating, the method of the invention accelerates the speed of planting and slowing down of the dendrobium bottle seedlings, improves the survival rate at the seedling stage, and promotes the germination of new shoots. The planting cycle of Dendrobium is greatly shortened, and the effective components in the plant are greatly increased. This planting control method is practical, has no geographical restrictions, is suitable for promoting planting in any area, and has great commercial value.

The invention relates to a well drilling machine, in particular to a plugging-assembly type well drilling machine comprising a frame made of channel steels and / or angle iron, a power source, a gearbox, a hoist, a rotary machine head, a tower and a main drilling rod which is located in the rotary machine head. The power source, the gearbox, the hoist, the rotary machine head and the tower are fixed to the frame; a suspending pull rope is wound on a hoisting drum of the hoist, one end of the suspending pull rope penetrates a guide wheel of the tower to fix to an elevator, the elevator is connected to an elevating head, and a tap is fixed below the elevating head. The power source, the hoist, the gearbox and the rotary machine head are fixed to the frame through a plugging type connecting frame and a locking limit device. Thus, the plugging-assembly type well drilling machine has the advantages that structure is simple, disassembling is facilitated, transportation is benefited, well drilling efficiency is improved, one single well drilling machine is light, work intensity is reduced, and wells can be drilled without geographical restrictions.

The invention provides a ventilation and temperature reduction device of an overhead travelling crane air conditioner with a natural cold source and relates to a ventilation and temperature reduction device, aiming at solving the problem that the physical health of a travelling hoist driver is influenced because the operation temperature of the overhead travelling crane in a workshop is high. In the invention, an air supply outlet is arranged on a support casing, a stuffing box and a blower are respectively and fixedly arranged in the support casing, the air supply end of the blower is opposite to the air supply outlet, a water collection disk is arranged in the support casing and positioned below the stuffing box, a water outlet on the water collection disk is connected with a water tankby a first pipeline, the water tank is connected with a water inlet of a water pump by a second pipeline, a spray nozzle is installed on one end of the pipeline, one end of the pipeline provided withthe spray nozzle is arranged on the right upper end of the stuffing box, the other end of the pipeline is connected with a water outlet of the water pump, a moisture absorption material is filled in the stuffing box, and the bottom of the stuffing box is provided with a plurality of water leakage holes. The invention utilizes the moisture absorption material to reduce the temperature in an overhead travelling crane operation room and improves the working environment in the overhead travelling crane operation room, and the working environment with low temperature and moisture is beneficial to the physical health of the driver of the overhead travelling crane.
