Introduction Of New Variety Of High Quality Spring Wheat And Research On Advanced Planting Techniques In Baiyin

High quality wheat production is the last choice in the stage of agriculture development. It's also the important method to quicken agriculture structure adjustment steps,increase farmer's income and agriculture efficiency,advance agriculture and economic development sustainably and healthily in Baiyin area.In order to meet the demand of Bayin high quality wheat production,support Baiyin high quality noodle wheat production and solve the problem of the shortage of high quality varieties of spring wheat,imperfect planting techniques and unreasonable variety distribution in Baiyin,this paper introduced about 40 high quality spring wheat varieties and studied their growth features,yield,quality and adoption in Bayin.The high quality variety planting techniques were thereby studied and put forward in Baiyin.The advanced planting techniques and the high quality varieties of spring wheat were demonstrated and extended in Baiyin.Sifted 3 high quality wheat varieties can be extend to irrigation area in Baiyin city;they are Ningchun-32,Ningchun-33,Ganchun-20.Parallel 2 varieties J659 and Xinchun 8.The average yield of these varieties is 6517.5,6496.5,6391.5,6442.5,6193.5kg/hm².Protein conten is 14.27%,14.5%,15.3%,14.9%,16.4%;Wet gluten content is 31.5%,29.7%,33.4%, 34.8%,33.6%.Dough stability time is 11.8,5.8,9.8,5.8,19.2min individually.Effects of the planting period,the period and amount of nitrogen fertilizing and other planting techniques on yield and quality in high quality spring wheat were studied.The planting technique of high quality and high yield of spring wheat in Baiyin were summarized: 1)planting in March 10-15.2)the suitable method of fertilizing nitrogen is integrating the base fertilizer and the top-dressing of fertilizer.In the base of fertilizing P₂O₅ 84kg/hm²,the amount of fertilizing nitrogen is 172.5kg/hm².The suitable period of adding nitrogen is in flower time.The amount of adding nitrogen is 86.25kg/hm².3)defined the best planting techniques of high quality spring wheat:the density is 5289-5782 thousand/hm²,N is 226-234kg/hm²,P₂O_s is 113-117kg/hm²,K₂O78-91.5kg/hm²,duoxiaozuo(100-200ppm) is 450kg/hm².According to resource condition of Baiyin,variety region test result in Baiyin and the biological adaptability,distribute and demonstrate the high quality spring wheat variety.In 2004 and 2005,demonstrated and extended high quality wheat 3706.7 hm²,average yield is 5860.5kg/ hm²,increased 6.5%,increased 1346t wheat totally.Among them,Jinghui irrigation area is 1120 hm²,average yield is 5848.5kg/hm²,increased 6.7%than ck;Jingdian irrigation area is 1433.3 hm²,average yield is 6294kg/hm²,increased 6.6%than ck;Liuchuan irrigation area is 513.3 hm²,average yield is 6126kg/hm²,increased 6.3%than ck;Xingdian irrigation area is 640 hm²,average yield is 5182.5kg/hm²,increased 6.2%than ck.
