小麦种子在收割、堆放、脱粒、运输和贮藏过程中,遇到不良的环境条件都会影响种子的发芽能力。因此,除在上述过程中采取一系列的措施,保证种子质量外,为了掌握小麦种子的生活力,在播种前,必须做好发芽试验。这是鉴定种子品质好坏,确定能否做种和确定播种量的重要依据。同时,根据发芽试验结果,可以采取不同措施进行选种,以保证苗全苗壮及经济用种,为小麦丰收打下良好基础。 Wheat seeds in the harvest, stacking, threshing, transportation and storage process, the adverse environmental conditions will affect the seed germination capacity. Therefore, in addition to a series of measures taken in the above process to ensure the quality of seeds, in order to grasp the viability of wheat seeds, germination tests must be carried out before sowing. This is an important basis for identifying the quality of seeds and determining whether they can be used as seeds and the seeding rate. At the same time, according to the germination test results, we can take different measures to select the seedlings in order to ensure the whole seedling and economic seedlings, and lay a good foundation for wheat harvest.
