1992年我区水稻生产出现了历史上多年不遇的大幅度、大范围、大面积的减产。全区93百多亩水稻总产比上年减少20.73％,单产减少23.34％,仅次于大减产的1976年。从产量构成因素看,一部分地区穗数、穗粒数、穗粒重三因素同时减少,大部分是除收获穗数外,其它两个因素同时减少,这 In 1992, the rice production in our region witnessed a drastic, large-scale and large-scale yield reduction that has not hit the history of many years in history. The total output of more than 93 mu of rice in the region decreased by 20.73% over the previous year and the yield decreased by 23.34%, second only to the sharp decrease in 1976. From the perspective of yield components, the number of spikes, grains per spike and weight of spike were decreased in some areas at the same time, most of which were reduced at the same time except for the number of ears harvested, which reduced the other two factors simultaneously
