一、受涝概况1972年冬至1973年春,浙江多雨,对嘉兴、嘉善等平原易涝地区的草子(指紫云英,下同)生产,带来了很大影响。根据1973年3月中嘉善县召开的、有25个大队参加的座谈会上分析估计,在这些生产单位里,草子鲜草亩产在2500斤以上、作本田基肥可以自给有余的只约占30%。40%左右的草子田亩产在2500斤左右,仅能本田自给。

First, the waterlogging profile 1972 winter to 1973 spring, rainy Zhejiang, Jiaxing, Jiashan and other plains in the flood plain areas of grass (referring to the Violet, the same below) has brought great influence. According to an analysis and discussion held by a group of 25 battalions held in Jiashan County in March 1973, it is estimated that in these production units, the yield of grass fresh grass is more than 2,500 kg, and only about 30% %. About 40% of the grass fields yield about 2,500 pounds, only Honda self-sufficiency.
