施肥量和种植密度对强筋小麦泰山27产量和品质的影响

目的]获得强筋高产小麦新品种泰山27良种良法配套的栽培模式。方法]以泰山27为材料,设3个主处理和3个副处理,共9个组合,研究施肥量和种植密度对其产量和品质的影响。结果]泰山27在施纯氮225 kg/hm~2、基本苗240×10~4~300×10~4株/hm~2的条件下,产量最高,达8 933.40 kg/hm~2;在施纯氮300 kg/hm~2、基本苗360×10~4株/hm~2的条件下,产量最低,仅7 566.60 kg/hm~2。结论]泰山27适宜的基本苗为240×10~4~300×10~4株/hm~2,氮肥用量宜结合不同的地力条件,在保证水分的前提下,酌情施肥,以免造成水肥胁迫,影响产量。

Effects of Fertilizing Amount and Pla nting Dens ity on Yield and Quality of Strong Gluten Wheat Taishan 27

Objective] To obtain the improved varieties and fine technique cultivation pattern of high-gluten high-yield wheat variety Taishan 27.Method] With Taishan27 as the research materials, three main treatments and three assistant treatments were designed, with in all 9com -binations.Effects of fertilization amount and planting density on the yield and quality of Taishan 27 were researched.Result] Taishan 27 has a higher yield( 8 933.40 kg/hm2 ) under the condition of 225 kg/hm2 nitrogen and 240 ×104 -300 ×104/hm2 basic seedlings.However, there was the lowest yield of 7 566.60 kg/hm2 under the conditions of 300 kg/hm2 nitrogen and 360 ×104/hm2 basic seedlings.Conclusion] The suitable basic seedling number of Taishan 27 is 240 ×104 -300 ×104/hm2 .On the premise of guarantee the moisture in soil conditions, we should use appropriate quantity of nitrogen application to avoid water and fertilizer stress and yield reduction.
