摘要:

为探索兴化市小麦适宜的播期,研究不同播期对小麦生长发育和产量的影响,于2022年在江苏(兴化)现代农业(稻麦)科技综合示范基地进行了扬麦23不同播期的试验,播期分别为10月27日、11月3日、11月10日、11月18日、11月25日。试验表明,播期显著影响小麦生育进程,随着播期的推迟,出苗期、拔节期、抽穗期等生育期依次延后,但是成熟期差异不大,小麦全生育期缩短。播期越晚,主茎叶龄越小,相同时期的单株分蘖数、大分蘖数、单株次生根数越少。每667 m2穗数、每穗粒数、实际667 m2产量随着播期的推迟先增大后减小,千粒重随着播期的推迟逐渐减小。蛋白质含量、沉降值、湿面筋含量随着播期的推迟呈现先升高再降低的趋势。

Abstract:

In order to explore the suitable sowing dates for wheat in Xinghua and study the effects of different sowing dates on growth, development and yield of wheat, an experiment was conducted on Yangmai 23 with different sowing dates on October 27, November 3, November 10, November 18, and November 25 in 2022 year at the Jiangsu (Xinghua) Modern Agriculture (Rice and Wheat) Science and Technology Comprehensive Demonstration Base.The experimental results showed that the sowing date significantly affected the growth process of wheat. With the delay of the sowing date, the seedling stage, jointing stage, heading stage were successively delayed, but the difference in maturity stage was not significant, and the entire growth period of wheat was shortened. The later the sowing period, the smaller the age of the main stem and leaves, and the fewer tillers per plant, the larger tiller numbers, and the fewer secondary roots per plant in the same period. The number of spikes per 667 m2, the number of grains per spike, and the actual yield per 667 m2 increased first and then decreased with the delay of the sowing date, while the thousand grain weight gradually decreasesd with the delay of the sowing date. The protein content, sedimentation value, and wet gluten content showed a trend of first increasing and then decreasing with the delay of sowing time.

Key words: sowing dates, Yangmai 23, growth and development, yield
