一九七八年十月份霜降以前,我们把十五棵水葫芦分别放在五个直径二十公分的瓷盆里,瓷盆里装塘泥和水,放在办公室正面窗台上.到一九七九年四月一日扩繁到六十盆,共计六百余棵,比初期增加四十倍,相当于小暖窖的产量.为水葫芦安全越冬找到新的办法. Before the fall of the ice in October 1978, we put fifteen water hyacinths in five porcelain pots of twenty centimeters in diameter, each containing pond mud and water in the frontal windowsill on the office. On April 1, 1979, it was expanded to 60 basins, totaling more than 600 trees, an increase of 40 times over the previous period, equivalent to the yield of a small warm pit, and finding a new solution for the safe winterization of water hyacinth.
