我省双季晚稻,尤以杂交水稻中迟熟种,由于需要满足其较长的生育期,必须提早播种,而移栽却受早稻茬口的限制不能提早插秧,以致秧龄过长,秧苗徒长,难以培育成矮壮秧,影响了产量的提高。针对生产上这一问题,我们在中国水稻研究所的协助下,试用多效唑药剂控制二晚秧苗徒长,促使秧苗分蘖早生快发,对培育矮壮秧和提高产量都取得明显效果。 Double-season late rice in our province, especially hybrid rice late-maturing species, due to the need to meet their longer growth period, must be sown early, but transplanted by the early rice stubble restrictions can not be early planting, resulting in long seedling age, Difficult to cultivate into short seedlings, affecting the yield increase. In response to this issue of production, we tried the application of paclobutrazol to control the growth of two-year-old seedlings with the help of the China National Rice Research Institute, prompting the rapid emergence of tillering in the early growing season and achieving remarkable results in cultivating short-stalked seedlings and increasing yield.
