The invention relates to a tea garden rotary cultivator, comprising a frame, a power device, a rotary blade, and a walking wheel, wherein a fixed mount is arranged below the frame, the walking wheel is arranged below the frame and in front of the rotary blade, a depth limiting rod is arranged behind the rotary blade and below the frame, the upper and lower positions of the depth limiting rod on a locating sleeve are adjustable, and an arc plate is arranged below the depth limiting rod; and the power device comprises a diesel engine and a speed reducer, the rotary blade is provided with a driven disc which is connected with a driving disc on the speed reducer through a transmission chain A, and the driven disc is connected with a driving disc on the walking wheel through a transmission chain B. The tea garden rotary cultivator provided by the invention is suitable for loosening soil and plowing in a tea garden, the diesel engine provides power to ensure that the walking wheel and the rotary blade are driven to rotate so as to achieve walking and plowing of the rotary cultivator, wherein by adjusting the upper and lower positions of the depth limiting rod, the depth of soil tillage is controlled, manpower is saved, and the efficiency of plowing and loosening the soil is increased.

The invention discloses a facility leak-stopping and evaporation-limiting cultivation method for a non-arable land and belongs to the technical field of facility horticulture. The method comprises the steps of changing cultivation troughs, which are constructed aboveground, into cultivation ditches, which are excavated underground, extending a soilless culture matrix or organic soil into all substrates which are suitable for the growth of cultivated crops, meanwhile, fully covering the ground and the cultivation ditches with mulching films, adopting an under-film ditch-irrigation irrigation way, and normalizing specifications for irrigation ditches. According to the method, soil evaporation is minimized, and both leak stopping and evaporation limiting are achieved, so that the water saving potential is higher; and the construction cost is low, and the applicable range is broad.
