1997～1998年麦作期间,气候异常,灾害频繁严重。特点为:苗期气温偏高,持续阴雨寡照;中期经历两次低温冻害,其中1998年1月中、下旬,气候降至零下5.8℃至零下6.8℃,3月19日～22日,又降雨雪冰粒。拔节至抽穗阶段,又阴雨寡照,灌浆期又遭高温逼熟,对麦子生产甚为不利。但我场始终贯彻麦子叶龄模式和高产群体质量栽培的综合技术路线,在大灾之年的1998年,全场17000亩麦子的实际单产仍达319.7kg的较好水平。其中千亩丰产方的麦子经上海市农工商(集团)总公司的专家组现场
During the period from 1997 to 1998, the weather was abnormal and disasters were frequent. The characteristics are as follows: the high temperature in seedling stage lasts for rain and light; the middle stage experiences two low-temperature frost damage. In mid-and late 1998, the climate drops to minus 5.8 ℃ to minus 6. 8 ℃, and on March 19 to 22, Snow ice tablets. Jointing stage to heading stage, but also overcast and rainy, grain filling temperature has also been cooked, wheat production is very unfavorable. However, we always carry out the wheat leaf age model and high-yielding mass cultivation of integrated technology route in the disaster year 1998, the audience 17000 acres of wheat actual production still reached a good level of 319.7kg. One of the acres of high-yield side of the wheat by the Shanghai Agriculture and Industry (Group) Corporation’s expert group site
