近几年来,由于复种指数的提高和平整土地,冬绿肥播种季节推迟,产量降低,有机肥料减少,化肥施用量增加,造成土壤板结,影响了农作物产量进一步的提高。我县贫下中农和干部为了夺取农业更大的丰收,积极地种好冬绿肥,逐年扩大种植面积,1976年全县种植9万多亩,1977年计划种植11万多亩。 In recent years, due to the improvement of multiple cropping index and land leveling, seeding season of winter green manure is delayed, output is reduced, organic fertilizer is reduced, and fertilizer application rate is increased, resulting in compaction of soil, which further affects crop yield. In order to seize a greater harvest of agriculture, the poor and middle-level peasants and cadres in our county actively planted winter green manure and expanded the planting area year by year. In 1976, the county planted more than 90,000 mu of land and planted more than 110,000 mu of land in 1977.
