摘要
通过研究小麦受冻死穗的成因，冻后生长发育特性的变化和预防补救措施的效应。结果表明：拔节期显著提前是受冻死穗的生物学因素，也是预测冻害的核心指标；小麦受冻后具有较强的自我恢复调节能力；适期插种、降低基本苗、培育高质量群体能有效地控制冻害；多效唑拌种、化控、适时适度镇压、浇泥浆等措施均能有效地减轻冻害；冻后迅速补肥是受冻小麦夺取高产的关键技术措施。
The cause of ear dying,the growth and development characteristics after freezing damage and the effec-tiveness of integrated control techniques in two wheat cultivars(Tr. aestivum L.CV.Yangmai 5 and Yangmai 158)were studied in 1994～1995.Elongating too early was the biological reason for ear dying and the key index to forecastfreezing damage. Raising high-quality population could avoid freezing damage and dressing seeds with PP_(333)or pouringmud on wheat plants could reduce its influence. Fertilizing in time could promote the self-recovery of freezing damagedplants,so it was on effectlve measure to achieve a high yield in freezing damaged wheat.
