Abstract

The invention discloses a device for measuring grain yield in a test plot. The device comprises a rack; a material containing box and a material receiving box are sequentially arranged in the rack ina connected manner from top to bottom; the material containing box comprises an upper box body and a grain moisture content measuring device fixedly arranged at the bottom of the upper box body; and amaterial containing box weight measuring device is arranged in the rack corresponding to the position of the material containing box. The device has the advantages that the structure is simple and ingenious, the measurement is facilitated, the total weight, the volume weight and the moisture content of the grains harvested in the test plot can be accurately measured at one time, the labor intensity and the measurement cost on manual signal collection are reduced, and the detection efficiency and the measurement accuracy are improved.

Description

technical field [0001] The invention relates to the technical field of experimental field (community) breeding, in particular to a device for measuring grain yield in a test plot, and also relates to a measurement method for measuring grain yield in a test plot. Background technique [0002] In agricultural grain breeding experiments, the area of ​​each experimental plot is usually 12.24m 2 about. The yield inspection of each plot breeding field is one of the important means to evaluate the yield effect of technical achievements, and all data must be true, accurate and reliable. [0003] At present, when checking and accepting the output of experimental plots in domestic plots, various information collection is mostly done manually, which has problems such as high labor intensity, low efficiency, and poor quality of test data. In order to reduce labor costs and improve detection efficiency and detection accuracy, it is necessary to design a special measuring device with mo...
