当前检查飞虱卵条是根据产卵痕变褐色来进行的,而试验证明从飞虱产卵到变褐色需要36个小时左右,因此,在田间查卵时就会遗漏很大一部分刚产的卵,从而造成检查结果偏低于实际卵量,增加对飞虱发生期,发生量预测的不准确性。为此,我们对飞虱准确查卵进行了一些试验,得出如下方法: 查卵方法 按一般查飞虱卵取样法取回稻株,洗净,切除根,注意不能弄伤叶鞘组织。然后放入医用碘酒溶液(浓度为3％)中染色半分钟,为了节省碘酒也可用其5倍溶液(浓度为0.6％)染色一分钟左右,取出用清水冲洗干净,进行检查。
The current inspection of planthopper eggs is based on the browning of oviposition marks, and the test proves that it takes about 36 hours from egg-laying to browning. Therefore, a large part of freshly produced eggs Eggs, resulting in the test results lower than the actual amount of eggs, increase the occurrence of planthopper, the amount of inaccurate forecast. For this reason, we carried out some tests on the accurate oviposition of planthoppers and obtained the following methods: The method of ovulation The rice plants were retrieved according to the general test of planthopper eggs, washed, and the roots removed, taking care not to injure the sheaths of the sheaths. And then into the medical iodine solution (concentration of 3%) staining half a minute, in order to save iodine can also use its 5 times the solution (concentration of 0.6%) staining for about a minute, remove and rinse with water for examination.
