High-precision seed and fertilizer positioning and simultaneous sowing device for field test

Abstract

The invention relates to the technical field of agriculture, and discloses a high-precision seed and fertilizer positioning and simultaneous sowing device for a field test. The device comprises a plate body and a threaded column, the lower surface of the plate body is fixedly connected with a lower cylinder, both sides of the upper surface of the plate body are provided with slots, each slot is internally provided with an elastic bent plate, the lower end of the lower cylinder is fixedly connected with a transmission soil turning mechanism, the transmission soil turning mechanism is arranged to be matched with an enclosing plate, a jacking column downwards drives the threaded column to move into the transmission soil turning mechanism, and meanwhile the transmission soil turning mechanismis matched to enclose soil around crops below the lower cylinder. In the descending process of the transmission soil turning mechanism, digging claws in the transmission soil turning mechanism drive the enclosing plate to move upwards to enable soil around the crops to sink, the application amount of fertilizer in the soil around the crops can be controlled through the rotating amplitude of the lower cylinder driven by the jacking column and the threaded column, and the fertilizer application amount is effectively controlled; and the condition of inaccurate fertilization is avoided, and the accuracy of a fertilization test is ensured.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a seed fertilizer positioning simulcaster for field experiments with high precision. Background technique [0002] To evaluate the effect of formula fertilizer or to establish the quantitative relationship between vegetable yield and fertilization amount will involve the problem of experimental design. Field experiment is the most effective way to test the optimal fertilization amount, fertilization ratio, fertilization period, and fertilization method. It is the basic link to verify the soil nutrient test method and establish a supporting system for fertilization. [0003] At present, when the amount of fertilizer is applied to the field test in the laboratory, the fertilizer is manually applied to the land with the test, and since the fertilizer needs to be far away from the roots and branches of the crop during fertilization, when the fertilizer is manually applied around ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a high-accuracy seed fertilizer positioning simulcaster for field tests, which can effectively control the amount of fertilization, avoid inaccurate fertilization, and ensure the accuracy of fertilization tests and other advantages, it solves the problem that it is not only inconvenient to control the position of the fertilizer on the land when the fertilizer is applied manually around the crops, but also may not be able to control the amount of fertilizer applied, which may affect the results of the experiment
