Problems solved by technology

[0004] However, there are two problems in the existing technology: on the one hand, it is necessary to manually peel the grains from the cobs, which is cumbersome and difficult to carry out on large-scale samples; on the other hand, the drying operation requires a long period, and the timeliness of data acquisition not tall

Embodiment Construction

[0012] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0013] In order to overcome the problems of cumbersome operation and poor timeliness of data caused by manually peeling off the kernels when measuring the corn grain filling rate in the prior art, an embodiment of the present invention provides a method for measuring the corn grain filling rate.

[0014] Since during the grouting process of corn kernels, as the carbohydrates are gradually transported into the kernels, the shape of the kernels gradually expands, and there is a linear relationship between the volume of the kernels and the dry weight. Therefore, the embodiment of the present invention is based on the projection of the top of the corn kernels at a certain time ...

Abstract

The invention provides a measurement method of a corn kernel grain filling rate and an apparatus thereof. The measurement method is characterized by measuring a projection area of a corn kernel top and then representing a kernel grain filling rate. An automation degree of the grain filling rate is increased, operation is simple, and a key technology is provided for measuring the corn kernel grain filling rate in a large-scale and high-flux mode.

Description

technical field [0001] The invention relates to the field of agricultural product detection, in particular to a method and device for measuring the filling rate of corn grains. Background technique [0002] Maize grain filling period to maturity period is an important stage to determine the yield and quality of corn, and the effect of grain filling rate on grain weight is greater than that of effective grain filling period. Breeding and planting maize varieties with fast filling speed is particularly important for improving yield and quality. [0003] At present, the measurement method of grouting rate is mainly weighing method: take a certain amount of corn kernels (about 1000 kernels), weigh them after high-temperature drying, carry out once a day after the grouting starts, and calculate the weight change of 1000 corn kernels after drying The rate is the filling rate. [0004] However, there are two problems in the existing technology: on the one hand, it is necessary to...
