在超高产栽培条件下,采用裂区试验设计方法,研究春小麦新品系与种植密度对产量结构的影响,初步结果表明:永3251、永T28在丰产性、综合抗性方面均优于对照品种宁春4号,是具有较大增产潜力的超高产新品系。在超高产栽培条件下,永3251种植密度以487.5万/hm2产量最高,永T28种植密度以375万/hm2产量最高。
The results showed that Yong3251 and YongT28 had better yield and comprehensive resistance than that of the control variety Ning-32 in the condition of super-high-yielding cultivation, and the experimental design method of split zone was used to study the effect of new spring wheat lines and planting density on yield structure. Spring 4, is a super-high yield new line with greater yield potential. Under the condition of super-high-yielding cultivation, Yong3251 had the highest planting density of 4.8775,000 / hm2 and the highest permanent planting density of 3.75 million / hm2.
