一个小麦优良品种从选育到生产应用需要经过区域试验、生产试验,审定、示范、推广等一系列过程,其中区域试验尤为重要,它是育(引)种与生产应用的中间试验,它可以客观、公正、科学地评价各地育成小麦新品种在不同麦区的丰产性、稳产性、抗逆性、适应性和品质特性,为小麦品种审定、生态区划、品种布局及合理利用提供重要科学依掘,加速小麦新品种推广,提升小麦生产能力,确保粮食安全。1播种前种子准备在收到育种家寄来的种子到播种还有一段时间,如不好好管理,种子容易出现霉变、虫蛀、发芽率减退,不能一播全苗等。因此,要做好以下工作：1．1晒种
A good variety of wheat needs to go through a series of processes of regional experiment, production test, validation, demonstration and popularization from breeding to production and application. The regional experiment is especially important. It is an intermediate test of breeding and production and application. It can Objectively, impartially and scientifically evaluate the characteristics of high yield, stability, stress resistance, adaptability and quality of new wheat cultivars in different wheat regions in different regions, and provide important scientific basis for wheat variety validation, ecological zoning, variety layout and rational utilization Dig, accelerate the promotion of new wheat varieties, improve wheat production capacity, ensure food security. 1 before sowing seed preparation After receiving the seeds sent to breeders to sowing for a period of time, if not well managed, the seeds are prone to moldy, moth-eaten, the germination rate decreased, can not be a whole plant seedlings and so on. Therefore, to do the following work: 1.1 sunburn
