对农作物品种大面积推广应用的思考

Reflections on Large Scale Extension and Application of Crop Varieties

常言道“好品种是育种家选育的,大品种是种业推出来的”,因此一个优良的农作物新品种,如何能迅速应用于生产,尽快发挥其增产增收效用,进而成为主栽品种,很大程度上取决于种业对品种特性的认识和种业的推广策略。新审定的农作物品种并不是在审定委员会建议的同类适宜生态区的每一个小区域都能适应,常常存在着不同地区小气候的变化,而表现出品种适应性的差异,需要种子企业进一步的布点试种,以找到该品种的最适生长地域。因此,分析作物品种推广应用策略,明确农作物品种的市场需求和品种的特性,进一步细化作物品种的最适地区,加强品种提纯复壮,严控种子质量对农作物品种的大面积推广应用具有重要意义。

It is often said,"Good varieties are bred by breeders,but widely adopted varieties are introduced by the seed industry."Therefore,the rapid application of excellent new crop varieties in production,their quick realization of increased yields,and their ultimate status as major cultivated varieties depend largely on the seed industry's understanding of variety characteristics and its promotional strategies.Newly approved crop varieties may not be suitable for every small area within the same ecologically appropriate zone recommended by Crop Variety Approval Committee.This was often due to frequent microclimate variations in these areas,resulting in differences in variety adaptability.Therefore,it is essential for seed enterprises to further distribute seed for trial planting to identify the most suitable growing area for each variety.It is important to analyze the strategies for the promotion and application of crop varieties,clarify the market demand for crop varieties in production and the characteristics of these varieties,specify the corresponding ecological zones for crops,and enhance the variety of purification and rejuvenation,and strictly control the quality of seed.These factors play an important role in the large-scale demonstration and application of crop varieties.
