去年,我们丰宁县旱情严重,甜菜播种后一个多月没有下雨,种子不能发芽,不少同志耽心种子有问题,我们根据高梁玉米用红四氮唑染色法测定种子生活力的办法,对甜菜种子进行了发芽率测定试验,取得较好效果。原来认为种子有问题的三千多亩甜菜地,现在苗情良好,节约种子九千多千,经费一万余元。一、试验结果为了使红四氮唑染色法符合发芽率,实际我们用两组比较法,即从同一个样品中取出两组种,一组种子用红四氮唑染色,另一组用常规发芽法发芽,然后比较两组结果。 Last year, we had a serious drought in Fengning County. There was no rain more than a month after sowing the beet, and the seeds could not germinate. Many comrades are worried about the problem of seeds. Based on the method of determining the viability of the seeds of sorghum by red tetrazolium staining, Beet seeds germination rate determination test, and achieved good results. The original three thousand acres of bee that think the seed has the problem, now the seedling is good, saves the seed ninety thousand, the fund more than ten thousand Yuan. First, the test results In order to make the red tetrazolium staining in line with the germination rate, in fact, we use two sets of comparison method, that is, from the same sample removed two groups of species, a group of seeds stained with red tetrazolium, the other group with conventional Sprouting germination, and then compare the two groups of results.
