Water supplementing device for agricultural greenhouse planting

Abstract

The invention belongs to the technical field of agricultural greenhouse planting tools, particularly relates to a water supplementing device for agricultural greenhouse planting, and provides the following scheme for solving the problems that in the irrigation manner of a water supplementing device for agricultural greenhouse planting in the prior art, a water suction pump is blocked by granular medicine, and a water pipe is prone to frost cracking in cold winter. The water supplementing device comprises a reservoir and a greenhouse framework with the upper end connected with an arc-shaped top, the lower end of a cultivation base is fixedly connected with the reservoir, a plurality of insertion holes are formed at the side end of the cultivation base, supporting pipes are fixedly insertedinto the insertion holes, elastic water absorption cotton slivers are inserted into the supporting pipes, and water absorption cotton blocks are fixedly connected to the upper ends of the elastic water absorption cotton slivers; and a water squeezing mechanism is arranged at the top end in the greenhouse framework. Compared with the manner that irrigation is conducted through a water suction pumpin the prior art, the manner that water transfer irrigation is conducted through absorbent cotton can effectively solve the problem that the water suction pump is blocked and breaks down, and meanwhile the water pipe can be effectively prevented from frost cracking in cold winter.

Description

technical field [0001] The invention relates to the technical field of agricultural greenhouse planting appliances, in particular to a water replenishing device for agricultural greenhouse planting. Background technique [0002] During the growth of crops in greenhouses, it is often necessary to irrigate the crops. The frequency and time of irrigation should be determined according to the water demand characteristics of the plants, growth stages, climate, and soil conditions. In addition to the need for water, it also affects the growing environmental conditions of crops in many ways, affects the physical and chemical properties of the soil, and thus affects the soil fertility status and soil formation process as well as the yield and quality of crops. [0003] Existing irrigation devices for agricultural greenhouses generally use nozzles to spray water. For example, the Chinese patent publication number is CN204888198U, a kind of irrigation device for agricultural greenhous...

Problems solved by technology

[0004] However, this irrigation method has the problem of blockage of the water pump by granular drugs. In addition, the water pipes are prone to freezing and cracking in the cold winter. The above situations need to be repaired in time, which consumes manpower.
