Embodiment Construction

[0026] A specific example illustrates that the germination rate of hybrid rice seeds was tested using a SupNIR-1000 portable near-infrared spectrometer.

[0027] Experimental materials: two hybrid rice seed varieties, Fengyou 22 and Tianfengyou 084, were used in the experiment.

[0028] Rice seed aging method: In order to obtain rice seeds with different germination rates, the seeds are deteriorated to varying degrees by artificial accelerated aging methods. Randomly select 324g of uniform rice seeds of each variety as a test sample, and a total of 7 groups were subjected to artificial accelerated aging experiments. Put each group of samples into a 500ml beaker, and place it in a 2000ml large beaker with an appropriate amount of water, seal the large beaker with a plastic film and place it in an electric blast drying oven, at a temperature of 45 ° C and a humidity of Under the condition of 100%, aging 0h, 24h, 48h, 72h, 96h, 120h, 144h in turn, during the aging process, the r...

Abstract

The invention discloses a rapid lossless testing method based on a near infrared spectroscopy technology for a paddy rice seed germination percentage. The method includes: S1) collecting paddy rice seed samples and ageing the paddy rice seeds; S2) collecting near infrared spectroscopy data of the paddy rice seeds; S3) subjecting the paddy rice seeds to germination tests; S4) selecting wave bands of the near infrared spectroscopy data of the paddy rice seeds and pre-processing; and S5) building a paddy rice seed germination percentage model based on the near infrared spectroscopy technology, and examining. By collecting the near infrared spectroscopy data of the paddy rice seeds with different ageing time periods, selecting the wave bands of the near infrared spectroscopy data and pre-processing, the method builds the paddy rice seed germination percentage model based on the near infrared spectroscopy by adopting a partial least squares method. After testing, the model is accurate, reliable and practical. The method can achieve rapid, lossless and accurate testing of the paddy rice seed germination percentage.

Description

technical field [0001] The invention relates to a method for rapidly and nondestructively testing the germination rate of rice seeds, in particular to a method for rapidly and nondestructively testing the germination rate of rice seeds using near-infrared spectroscopy. Background technique [0002] China is the largest rice producer in the world. The rice planting area has reached 450 million mu, of which the hybrid rice planting area has reached 220 million mu. Stable production has become the guarantee of people's basic life. The germination rate of rice seeds is the premise of determining rice yield, and it is one of the most routine inspection indicators in seed quality inspection. At present, the germination rate test method of rice seeds is the germination test method. This test method not only needs to be pretreated, but also needs to be tested according to the conditions specified in the germination technology of crop seeds. The test conditions are harsh, and there a...
