今年我省晚稻种植面积大。由于夏温低,早稻成熟推迟,使晚稻季节比较紧张。几种主要病虫在早稻上发生量大,使晚稻病虫基数高。加之当前晚稻品种类型繁多,等等。因此晚稻田间管理工作更加复杂。为了夺取晚稻高产,必須抓紧抓好各項管理工作。田间管理工作应当从晚稻生长发育的需要出发,在搞好了育秧、插秧、整地等项工作的基础上,采取有效措施,从“早”从“細”落实,确保晚稻发足苗子,长壮个子,多結谷子,从而实现高产丰收,一般把田间管理分做三个时期来抓。
This year, our province planted a large area of late rice. Due to the low summer temperature, the delay of early maturing rice will make the late rice season more tense. The occurrence of several major pests in early rice is large, so that late rice pest base high. Coupled with the current variety of late rice varieties, and so on. Therefore, late rice field management is more complicated. In order to win late rice high yield, we must pay close attention to the management. Based on the needs of late rice growth and development, field management should take effective measures to improve the quality of late rice from “fineness” and ensure that late rice leaves are full of seedling and long and strong Sub-more, more knot millet, in order to achieve high yield, the general field management divided into three periods to grasp.
