栽培措施对小麦新品种陕麦159产量及其产量三要素的影响

Effects of Cultivation Practices on Yield and Its Components of A New Wheat(Triticum aestivum L.) Cultivar Shaanmai 159

[目的]探讨小麦(Triticum aestivum L.)新品种陕麦159适宜的播期和种植密度。[方法]采用2个重复5×5播期播量设计,研究播种期和种植密度对陕麦159产量及其构成要素的影响。[结果]在10月上旬播种,播种量115.5 kg/hm2时,陕麦159产量可以达到7 500 kg/hm2。播期播量对陕麦159成穗数的影响最大,穗粒数次之,千粒重最小。[结论]合理的播种期和种植密度有助于挖掘小麦品种的产量潜力。该研究可为实现该品种在生产上高产稳产提供科学的栽培依据。

[ Objective] The aim was to discuss a new wheat cuhivar Shaanmai 159 ＇s suitable sowing time and planting density. [ Method] A field experiment two duplicate 5 x 5 designs was conducted to study the effects of sowing time and planting density on the yield and its compo- nents of a new wheat cuhivar Shaanmai 159. [ Result] The results showed that the yield of Shaanmai 159 could up to 7 500 kg/hm2 when so- wing period was in early October and the sowing seed is 115.5 kg/hm2. The sowing time and seedling density had the greatest effects on spike number, the second on grain number per ear, and the smallest on 1 000-kernel weight of Shaanmai 159. [ Conclusion] The suitable combina- tion of sowing time and seedling density is favorable for the yield increase of wheat cultivar. And the study provides a scientifical cultivation ba- sis for realizing Shaanmai 159＇shigh and stable yield in production.
