Problems solved by technology

[0003] In the process of wheat seed quality testing, in the process of wheat vigor testing, because the wheat is relatively dry, it is easy to be unevenly sliced ​​when cutting the seeds, which will affect the detection. It is also impossible to intuitively understand the degree of emergence of wheat

Abstract

The invention discloses a wheat seed quality detection method. The wheat seed quality detection method comprises the following steps: S1, selecting seeds; S2, performing the imbibitions; S3, cutting the seeds; S4, staining the seeds; S5, examining the staining; S6, sampling the neatness; S7, calculating the neatness; S8, sampling weight of 1,000 wheat grains; S9, weighing weight of 1,000 wheat grains; S10, sampling the germination vitality; S11, seeding; and S12, judging the germination vitality. According to the method, the vitality, neatness, weight of 1,000 wheat grains and germination vitality of the wheat seeds are separately detected, the imbibitions are performed for the wheat before the staining, so that the average rate of the wheat granularity can be increased, the detection error caused by non-uniformity in slicing due to the excessive hardness can be avoided, the paper is used for performing the tensile strength test for the wheat seeds, the germination vitality of the wheat can be determined, the practical application is facilitated, the germination rate of the wheat sowed in the soil of different hardnesses can be determined, evidence and guarantee can be provided forthe practical application, the germination of the wheat can be known, and the wheat seed quality detection method is suitable for wide popularization.

Description

technical field [0001] The invention relates to the technical field of wheat seeds, in particular to a method for detecting the quality of wheat seeds. Background technique [0002] The wheat seeds are semi-winter, middle-early maturity, and the maturity stage is 1-2 days earlier than the control Yumai 49 and Xinmai 18. The seedlings are upright, with broad leaves, dark green leaves, medium tillering ability, early jointing in spring, rapid growth, fast polarization, early heading, and average spike rate. The plant height is about 77 cm, the plant type is compact, the flag leaf is wide and curly, the ear layer is neat, and the appearance is delicate. Ears are rectangular, with long awns, white husks, white kernels, semi-horny kernels, average plumpness, and medium black embryo rate. The average number of ears per mu is 366,000 ears, the number of grains per ear is 37.6, and the thousand-grain weight is 39.5 grams. Seedling growth is strong, medium cold resistance. Sensit...
