水稻抛秧技术从日本引入以后,已逐步发展成为我国水稻简化栽培的主要技术之一。目前我国水稻旱育抛秧技术主要有三种方式:(1)塑盘旱育抛秧。具有带土抛植、易抛秧、易立苗的优点,但其适宜秧龄短,培育壮秧难,育苗成本高。(2)肥床旱育抛秧。具有秧龄弹性大、利于高产的优点,但其秧苗根部带土量少,抛植困难,不易立苗。(3)无盘旱育抛秧。综合了塑盘旱育和肥床旱育抛秧的优点,采用“无盘抛秧剂”包衣,在秧苗根部形成“吸湿泥球”,利于抛植立苗,易培育壮秧,不受秧龄限制,利于高产,具有广阔的应用前景。
Rice throwing technology introduced from Japan later, has gradually developed into a simplified cultivation of rice in China one of the major technologies. At present, there are mainly three ways for rice cultivation and seedling throwing in paddy field in our country. With soil throwing, easy to throw seedlings, easy to stand seedlings advantages, but its suitable seedling age is short, nurturing strong seedling, seedling cost is high. (2) bed dry seedling throwing. With elasticity of seedling age, conducive to the advantages of high yield, but the seedling root with less soil, throwing difficulties, not easy to stand seedlings. (3) Diskless drought throwing seedlings. Comprehensive plastic plate dry cultivation and fertilizer bed dry throwing throwing advantages, the use of “diskless throwing agent” coating, the root of the formation of seedlings “moisture mud ball”, which will help throw seedlings, easy to cultivate strong seedlings, not Seedling age limit, conducive to high yield, has broad application prospects.
