Chinese Abstract

[目的]寻求4种播种基础因素适合2种穗型强筋小麦的最佳指标,比较2种小麦对这些因素的需求差异。[方法]大穗型强筋小麦以淄麦12号,小穗型强筋小麦以济南17号为试材,对其分别进行地力适应性、基本苗差异、播种期和适宜种植行距试验,并比较2种穗型强筋小麦对4种播种基础因素的需求差异。[结果]小穗型强筋小麦对土壤肥力的要求低于大穗型强筋小麦;大穗型强筋小麦的基本苗以225万~270万株/hm^2为宜,小穗型强筋小麦的基本苗为135万~180万株/hm^2,比大穗型小麦低80万株/hm^2左右;2种穗型强筋小麦的播种期一般相差5 d左右,平均播种行距相差5 cm左右。[结论]与小穗型强筋小麦相比,大穗型强筋小麦对地力条件要求高,适宜基本苗大,播种期晚,平均行距小。

English Abstract

[Objective] The study aimed to seek for the optimum indexes of 4 basic seeding factors that were suitable for the strong gluten wheat with 2 ear types and compared the difference of demand for these factors by 2 kinds of wheat. [Method] With big ear strong-gluten wheat variety Zimai 12 and small ear strong-gluten wheat variety Jinan 17 as the tested materials, they were made for the tests of soil fertility adaptability, basic seedlings differences, seeding stage and suitable sowing raw space and the difference of demand for 4 basic seeding factors by the strong gluten wheat with 2 ear types were compared. [Result] The demand of small ear strong-gluten wheat on the soil fertility was lower than the big ear strong-gluten wheat. The basic seedlings of big ear strong-gluten wheat were as suitable as 225×10^4-270×10^4 plants/hm^2 and that of small ear strong-gluten wheat were 135×10^4-180×10^4 plants/hm^2, being 80×10^4 plants/hm^2 lower than the big ear wheat. The seeding stages of the strong gluten wheat with 2 ear types generally differed by about 5 d and their mean sowing row spaces differed by about 5 cm. [Conclusion] Compared with spikelet type wheat, large ear wheat has high demand of ground fertility level and is suitable to large base seed, late sowing period and small average linewidth.
