Experimental device for effectively verifying effect of chemical fertilizer

Abstract

The invention discloses an experimental device for effectively verifying the effect of a chemical fertilizer and relates to the technical field of chemical fertilizers. The experimental device comprises a shell; a power box is arranged at the bottom end of an inner cavity of the shell; a rotating rod is arranged in the center of the power box in a penetrating manner; a motor I is arranged at the bottom end of the inner cavity of the power box; an output shaft of the motor I is provided with a gear I; the rotating rod is provided with a gear II engaged with the gear I in a sleeved manner; a rotating plate is arranged at the top end of the rotating rod; vertical rods are symmetrically arranged on the two sides of the top end of the rotating plate respectively; each vertical rod is uniformlyprovided with a plurality of culture trays; water pipes are symmetrically arranged on the two sides of the inner wall of the shell respectively and are uniformly provided with spray heads respectively; a disinfection lamp is arranged on one side, far away from the water pipes, of the inner wall of the shell; a water tank is arranged on one side of the top end of the shell; an air inlet device is arranged on one side, far away from the water tank, of the top end of the shell; and the inner wall of the shell is provided with a temperature sensor and a humidity sensor. The experimental device disclosed by the invention can effectively verifies the effect of the chemical fertilizer to growth of crops through experiments and is beneficial to research and production of the chemical fertilizer.

Description

technical field [0001] The invention belongs to the technical field of chemical fertilizers, and in particular relates to an experimental device for effectively verifying the effects of chemical fertilizers. Background technique [0002] Chemical fertilizers refer to fertilizers made by chemical methods that contain one or several nutrients needed for the growth of crops. Abbreviation for chemical fertilizers. Chemical fertilizers containing only one nutrient element that can be marked are called unit fertilizers, such as nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, and minor macro element fertilizers and trace element fertilizers. Chemical fertilizers that contain two or three of the three nutritional elements nitrogen, phosphorus, and potassium and whose content can be indicated are called compound fertilizers or mixed fertilizers. The solubility of the active components of a fertilizer in water is usually a measure of the effectiveness of a fertiliz...

Problems solved by technology

[0003] But now there is no device for experimenting with the effects of different levels of chemical fertilizers on crop growth. In practice, experimental fields are often used for experiments, which not only wastes land, wastes resources, increases R&D costs, but also makes it difficult to control external environmental factors to maintain consistency. It is inconvenient to test the optimal content of chemical fertilizers; different crops have different requirements for chemical fertilizer content. At present, it is difficult to control and compare the experiments of optimizing fertilizer content for different crops
