近些年来,高粱种子发芽率偏低这个问题一直困扰着我市的种子生产单位。特别是遇到秋季雨涝或霜期较早的年份,这种现象尤为突出,总有一部分高粱种子由于芽率偏低,给制种户和种子部门都带来了损失。针对这个问题,依据我们几年来的试验数据和工作经验,提出如下几点认识。 1.高粱种子应收获在蜡熟期高粱种子田和一般生产田不同,收获必须适当提前,宜在蜡熟期及时收获,即高粱穗的中部子粒开始变硬,穗下部子粒用指甲能掐出印并有少量浆,授粉后的30～35天,大体是高粱的晒
In recent years, the issue of the low germination rate of sorghum seeds has plagued the city’s seed production units. This phenomenon is especially noticeable in the years when rainfall or flood season is earlier, and some sorghum seeds always have low germination rate, which brings losses to seed producers and seed departments. In response to this problem, based on our years of experimental data and work experience, put forward the following understanding. 1. sorghum seeds should be harvested in the wax maturity sorghum seed fields and general production of different fields, the harvest must be appropriate in advance, should be harvested in a timely manner wax maturity, that sorghum spike middle of the grains began to harden, ear spikelets with nails can pinch out India and a small amount of pulp, pollination after 30 to 35 days, generally sorghum sun
