郑麦7698超高产栽培技术路线的探索与实践

Study on the Technology Route of Super-high-yield Cultivation for Zhengmai 7698

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。

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 con- cept 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.
