早稻大面积推广杂优威优64,是使水稻总产量大幅度提高的有效途径。但是,由于威优64生育期较长,一般要在大暑后收割,耽误了晚杂的适时栽插,直接影响晚稻夺高产。为解决这个问题,我进行了早稻二段育秧试验,实践结果,二段育秧能使威代64早熟高产,现将试验过程与结果介绍如下。试验过程1.浸种催芽2月24日用三环唑兑水浸种消毒,24小时后改用温水催芽。
Large-scale promotion of early rice hybrid Youyou 64, is an effective way to significantly increase the total output of rice. However, due to the prolonged growth period of Weiyou 64, it is generally harvested after the summer vacation and delayed the timely planting of late hybrids, which directly affects the late rice yield. In order to solve this problem, I carried out the second stage rice growing experiment, the results of practice, the second section of seedling can make early generation of Granville 64 high yield, now the test process and the results are as follows. Test process 1. Soaking seed germination February 24 with tricyclazole watered seed soaking, 24 hours later with warm water sprouting.
