Crop irrigation device and irrigation method

Abstract

The invention relates to a crop irrigation device and an irrigation method. The crop irrigation device comprises a water supply portion, a treatment mechanism and at least one irrigation portion. Thetreatment mechanism comprises a water storage portion, a circulation pipeline and mineral blocks. The water storage portion is internally provided with a water storage cavity in a hollow drum structure, the mineral blocks are arranged in a storage basket which is arranged at the top of the water storage cavity, the head end of the circulation pipeline is connected into the bottom of the water storage cavity, and the tail end of the circulation pipeline extends to a position above the storage basket and towards the storage basket. The irrigation method includes that irrigation is performed through the crop irrigation device, and water for irrigation is treated through the treatment mechanism. By the treatment mechanism for early treatment of the water for crop irrigation, the mineral blocksselected according to crop demands not only supplement essential fertilizers such as phosphorus and potassium to crops but also supplement trace elements for improving crop quality and increasing crop yield.

Description

technical field [0001] The invention relates to the field of planting, in particular to a crop irrigation device and irrigation method. Background technique [0002] In the cultivation of crops, the common irrigation methods are to directly collect or drain the irrigation water by means of flood irrigation, sprinkler irrigation, drip irrigation, etc., and the fertilizers required in the crop cultivation process are applied according to the demand. In the cultivation of crops using the above common irrigation methods, the trace elements used to improve the quality and yield of crops can only be provided by the soil, which is also a major reason for the excellent quality of specific crops in certain regions. Specifically, such as northeast rice, Wuyi rock tea, etc., although there are certain climate and other reasons, they are mainly closely related to the soil and irrigation water in the planting area. [0003] The Chinese patent with the application number 201810930059.9 d...

Problems solved by technology

However, this scheme has the following disadvantages: first, the construction cost of supporting facilities required by this method is high, and the construction requirements (such as 1000m riverbed needs to occupy space, terrain drop, etc.) are high, and the applicability is small; , the evaporation and infiltration of water in the sandstone riverbed over a kilometer will cause a large loss of irrigation water; third, the entire irrigation process of this scheme is seriously affected by climate, temperature, etc., and it is difficult to finely control the amount of irrigation, which wastes water and the final irrigation water The mineral content and trace element content in the water are affected by many aspects and are difficult to control; Fourth, the program has little connection with the crop growth cycle and seasonal climate change. For example, in hot summer weather, the water demand of crops is large, but the water in the program is due to Due to evaporation and other reasons, the loss also increases, which further increases the pressure on the previous aeration process. As a result, in the application of the method, it is necessary to build corresponding facilities according to higher irrigation demand indicators, but in winter and other times when the irrigation demand is small, the facilities are idle and wasteful.
