Embodiment Construction

[0013] The present invention will be further described below in conjunction with embodiment.

[0014] This embodiment provides a method for quickly measuring the moisture content of cotton seeds, which includes the following steps.

[0015] Step 1: Take a certain amount of cotton seed sample, put it into an airtight container immediately to prevent the moisture of the sample from changing, and put a label on it to make a good mark.

[0016] Step 2, fully mix the samples to be ground in the airtight container, grind according to the requirements in the "Crop Seed Inspection Regulations", and immediately put them into a grinding bottle for later use after grinding.

[0017] Step 3: Put in an aluminum box with constant weight, put the box cover under the box, record the weight of the box and the weight of the sample before drying, flatten the sample, put it in a drying oven at 130~133°C for 1 hour, and dry The starting point of dry timing is when the temperature in the drying bo...

Abstract

Belonging to the technical field of seed testing, the invention specifically relates to a method for rapid determination of cotton seed moisture. According to the invention, seeds are ground and then a high constant temperature drying method is employed to perform moisture determination, thus breaking through the technical limitation that traditional gossypium seed moisture determination is carried out by a low constant temperature drying method on ground seeds or slices. While accuracy and precision of the determination result are ensured, the determination time is greatly shortened, and the efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of seed determination, and in particular relates to a method for rapidly determining moisture in cotton seeds. Background technique [0002] In the "Crop Seed Inspection Regulations", the moisture content of crop seeds should be determined in accordance with the provisions of GB / T 3543.6-1995. Among them, the water content of cotton seeds should be measured by grinding or slicing and drying at a low temperature (that is, placing the seed sample Dry in an oven at 103±2°C for 8h). There are often factors such as too many samples and uncertain delivery time when seeds are purchased, sun-dried, and put into storage. According to this method, it takes one working day to complete the moisture measurement of a cotton seed, and the measurement takes too long. If the sample delivery time is not appropriate, the test result cannot be obtained on the same day, delaying the time of seed purchase or storage. Contents ...
