一九七八年七月十日我们发现在细绿萍的萍田四周的岸边和埂边长着象芝麻一样大小的浓绿幼嫩的孢子苗,就用小刀把孢子苗连泥撬来,采取四种方法进行越夏试验:第一,放置在平原水田里越夏.第二,放置在山边冷水田里越夏.第三,放置在室内的缸里越夏.第四,放置在墙上的缸里越夏.合计有孢子苗300多棵,结果四处均获成功.但由于管理不严,到八月一日只留下大孢子萍6朵.于是我们立即采取措施,精心管理,到立秋边就开始繁殖发展,一般5～6天翻一翻,九月一日长到200多张.随后4～5天翻一翻,生长最快的7天增四倍,到十月一日长到3斤多,到十二月一日长到1万多斤,到十二月底长到5万多斤,到一九七九年三月底发展到20多亩,共有孢子萍20多万斤,已推广外省、外县和本县各区十多万斤.
On July 10, 1978, we found that sporelings were sparged with a knife in the thick green young sporelets of the same size as the sesame seeds on the banks and sides of Ping-Pin, , Take four methods for summer trials: first, placed in the plain paddy in the summer .Second, placed in the mountain cold paddy summer .Third, placed in the interior of the cylinder in the summer.Fourth, place In the wall of the cylinder in the summer.A total of more than 300 spore seedlings, the results were successful everywhere, but due to lax management, only to leave the big spore Ping August 6. August so we take immediate measures, meticulous Management, to the beginning of the autumn began to reproduce development, usually doubled in 5 to 6 days, September 1 to more than 200. Then 4 to 5 days doubled, the fastest growing seven days by four times to 10 Grow to more than 3 pounds on the first day, grow to over 10,000 kilos on December 1, grow to over 50,000 kilos by the end of December and grow to more than 20 acres by the end of March 1979, More than 20 kilograms, has been promoting other provinces, counties and counties more than 100,000 kilos.
