小麦种子质量控制关键技术的初步研究

Preliminary Research on the Key Technology in Wheat Seeds Quality Control

以连麦2号和烟农19小麦种子为试验材料,考察了小麦种子质量控制的主要影响因素,探讨了小麦种子质量全程控制技术。结果显示:采用育种家种子、施用纯氮240kg/hm2、乳熟期去杂等技术有利于小麦繁种质量,烘干前发芽率与烘干后发芽率降幅呈负相关,烘干前含水量与烘干后发芽率降幅呈正相关。

Using the wheat seeds of Lianmai 2 and Yannong 19 as test materials, this paper investigated the main influence factors involved in wheat seeds quality control, discussed the currently existed wheat seeds quality control technologies. The results showed that using the seeds from breeders, application of nitrogen 240kg/hm2 and removal of impurity would improve the quality of seed through propagating. The germination percentage after drying was in negative correlation with that of before drying, while water content before drying had positive relationship with germination percentage.
