最近,山东农业大学完成的“小麦衰老生理和超高产栽 培理论与技术”研究,获得2001年度国家科技进步二等奖。 黄淮麦区和北方麦区的高产田,小麦生长后期常因早衰 而导致粒重下降,一般千粒重降低3～5克,严重影响了小麦 的单产提高和高产稳产。针对这一难题,经过16年的研究, 课题组终于发现了田间高产条件下小麦衰老的生理机制,探 索出建立在延缓小麦衰老基础上的小麦超高产(1/15公顷 Recently, Shandong Agricultural University completed “Wheat Physiology and Super-high Yield Cultivation Theory and Technology”, won the 2001 National Science and technology progress prize two. Huanghuai wheat and northern wheat high-yielding fields, wheat growth late due to premature aging and lead to decreased grain weight, grain weight generally reduced by 3 to 5 grams, seriously affecting the wheat yield per unit area and high and stable yield. In response to this problem, after 16 years of research, the research team finally found out the physiological mechanism of wheat aging in high-yielding fields and explored the ultra-high yielding of wheat based on delaying wheat senescence (1/15 hectare
