1、选用再生能力强,抗逆和丰产性好,生育期适中的杂交稻组合。如汕优桂33、汕优63D、优63、汕优64、Ⅱ优63等,再生能力较强,腋芽萌发快,苗壮,苗齐,再生稻易获高产。2、种好头季稻。种好头季稻是再生稻高产的基础,应做到适时早播,改进耕作栽培技术,加强田间的肥水管理,采取干干湿湿的灌溉方法,以促进禾苗早生快发。切实抓好稻纹枯病、三化螟、稻飞虱的防治工作,以保证水稻根系活力和茎基部健壮生长,提高再生能力。3、适时施足催芽肥。施好催芽肥能提高母茎中氮素含量,激发再生芽萌发,延长老根寿命,有利于新根生长,从而扩充营养物质,促
1, the selection of strong reproductive capacity, resistance and high yield good, moderate growth period of hybrid rice combinations. Such as Shanyougui 33, Shanyou 63D, You 63, Shanyou 64, Ⅱ You 63, and so on. The regenerative ability is strong. The axillary bud germinates fast, and its seedling is strong. 2, a good first season rice. The good first season rice is the basis of high yielding ratoon rice. It should be timely sowed in time, improve the cultivation and cultivation techniques, strengthen the management of fertilizer and water in the field, and take dry and wet irrigation methods to promote the quick emergence of seedlings. Effectively control rice sheath blight, Borer borer, planthopper prevention and control work in order to ensure root activity and rice stem robust growth, improve regeneration ability. 3, timely application of fertilizer buds. Applying germination fertilizer can improve the content of nitrogen in stem, stimulate the germination of regenerative bud, and prolong the life of old root, which is good for growth of new root, so as to expand nutrition and promote
