摘  要:
为进一步挖掘郑麦7698丰产潜力,充分发挥小麦新品种的增产作用,采用小区试验、高产攻关和总结群众高产典型相结合的方法,系统总结了郑麦7698超高产栽培技术路线,即:适期播种(10月10-20日)、充足底墒、适当播种量(180~210kg/hm2),增大群体的起点,使冬前分蘖数达到或接近高峰值;早春促控结合,以控为主,塑造理想株型;拔节后主攻大穗;倡导"绿色植保"的理念,建立高质量群体。郑麦7698超高产(11 340kg/hm2)产量结构是成熟期穗数698万穗/hm2,穗粒数39.5粒,千粒重48.1g。

摘  要:
To further exlore the yield potential of wheat cultivar Zhengmai 7698,the technology route of super-high-yield cultivation for Zhengmai 7698 was summarized by combining different methods including the plot experiment,high-yield research and high yield typical cases.The ideal cultivation technology for Zhengmai 7698 was as follows:selecting proper sowing time(October 10th to 20th),plenty of soil moisture,appropriate seeding rate(180-210 kg/ha) to increase the starting point of population,and to let the tiller number before winter reach or approach the peak value;taking the control as main measure in early spring while combining with the promotion,shaping the ideal plant types;mainly promoting the large spikes after jointing;advocating the concept of "green plant protection" and establishing the high-quality population.The yield structure of 11 340 kg/ha for Zhengmai 7698 was 6.98 million spikes/ha,39.5 grains per spike and 48.1 g of 1 000-grain-weight.
