摘要
为确定航天诱变小麦新品种航宇19高产高效栽培措施,采用二因素互作裂区试验设计,研究不同播期和密度对其产量及构成要素的影响,以明确该品种在豫中北部生态条件下的最优栽培措施。结果表明,播期、密度和播期×密度互作对航宇19产量及其构成要素均具有显著影响,且播期效应大于密度效应。播期对航宇19穗粒数的影响不明显,播期延迟后,单位面积成穗数和千粒重显著降低。密度增加后,成穗数相应增加,但穗粒数和千粒重降低。本试验条件下,航宇19的适宜播期为10月20日前后,且150~195 kg/hm2的播种密度可使航宇19达到更高的产量水平。说明通过调整播期与密度,可使该品种的单位面积成穗数和穗粒数显著响应,进而达到提高产量的目的。
Aiming to determine the high-yielding and high-efficiency cultivation measures for the aero-space induced new wheat variety Hangyu 19,a two-factor interaction split zone experimental design was adopt-ed to study the effects of different sowing dates and densities on yield and its components in order to clarify the optimal cultivation measures for this variety under the ecological conditions of northern central Henan Province.The results showed that sowing date,density and their interaction had significant effects on the yield and its components of Hangyu 19,and the effect of sowing date was greater than that of density.The effect of sowing date on the grain number per spike of Hangyu 19 was not obvious,and the panicle number per unit area and 1000-grain weight decreased significantly after delayed sowing date.The spike number per unit area increased accordingly after increasing the density,while the grains number per spike and 1000-grain weight decreased.Under the conditions of this experiment,the suitable sowing date of Hangyu 19 was around October 20th,and the seeding density of 150 to 195 kg/hm^(2) could make Hangyu 19 reach a higher yield level.The results indica-ted that the spike number per unit area and the grains number per spike of this variety could respond signifi-cantly to the adjustment of the sowing date and density,so as to achieve the purpose of improving yield.
