为了培育早稻壮秧,需要认真做好播种前的晒种、选种、浸种和催芽等工作。现把我们进行的早稻播前各项处理对发芽率和成秧率的影响试验结果,简介如下。一、晒种。我们用“广陆矮4号”和“广选3号”早稻品种于播种前进行晒1天和不晒的对比试验表明,晒比不晒的种谷吸水快,种胚萌动快,发芽齐,发芽率提高2—4%。这是因为晒种能促进种子的新陈代谢作用和增强生活力的缘故。二、选种。“好种出好苗,苗壮产量高”。要育成壮秧,必须选好种。好种的标准是:种子纯度高,
In order to cultivate strong seedlings of early rice, we need to do a good job in the sun before planting, selection, soaking and germination and other work. Now we carry out the early rice before sowing the germination rate and the rate of success of planting test results, the following is as follows. First, sunburn. We use “Guanglu dwarf 4” and “wide selection 3” early rice varieties in the sun before sowing for 1 day and non-drying contrast test shows that the sun is not drying than the fast drying seed germination, embryo germination fast, sprouting , Germination rate increased 2-4%. This is because sunning promotes seed metabolism and enhances viability. Second, the selection. “Good kind of good seedlings, Miao Zhuang high yield.” To grow strong seedlings, must choose a good species. A good kind of standard is: high purity seeds,
