The invention provides a crop potting experiment device capable of controlling water and fertilizer. The device comprises a cylindrical body, a convex arc-shaped permeable division board is arranged at the bottom of the cylindrical body and divides the cylindrical body into an upper chamber and a lower chamber, the permeable division board is provided with a feed inlet and at least one water and fertilizer discharging hole, a filter screen is arranged below the water and fertilizer discharging holes, a feed pipe is arranged at the feed inlet, and the top end of the feed pipe is provided with a cone-shaped charging bucket or a feed pipe cover; water discharging holes are formed in the lower end of the side wall of the cylindrical body, and each water discharging hole is provided with a water discharging hole cover; exhaust holes are formed above the water discharging holes, and each exhaust hole is provided with an exhaust hole cover; hand-holding parts are correspondingly arranged on the two sides of the upper end of the side wall of the cylindrical body respectively. The crop potting experiment device capable of controlling water and fertilizer is convenient to use, flexible and easy to master by an operator, in the crop water and fertilizer research process, water distribution is uniform, soil is not prone to hardening, the precision of an experiment is improved, errors caused by improper control over irrigation and fertilization in the experiment process are reduced, and the quality and efficiency of the research work are improved.
Description
technical field [0001] The invention relates to the technical field of agricultural planting test devices, in particular to a crop pot test device with controllable water and fertilizer and a method for using the same. Background technique [0002] Pot experiments are widely used because they are easy to control conditions such as water, fertilizer, and soil, and are conducive to accurate single-factor research. Generally, new technology exploration experiments related to crops, research with higher accuracy, and theoretical exploration of field experiment research are all realized through pot experiments. However, at present, the potted test devices used by scientific research departments are varied and crude, and the test operation is inconvenient, which is not conducive to rational irrigation and fertilization. The required environmental conditions cause excessive bias in the results of physiological studies of crops. Contents of the invention [0003] For this reason...
