多年来,川西平原杂交中稻高产栽培的基本技术框架是;以六三系统为主导组合; 3月底—1月初露地育秧(部分田3月下旬两段秧);本田亩施纯氮10公斤左右1亩裁1.5—1.7万穴,基本苗8—9万左右,适时防治病虫。在这样的技术结构条件下,正常年份一般亩产(市亩,下同)500公斤左右,单位面积产量很难有进一步的提高。在目前杂交稻组合没有大的变化条件下,水稻单位面积产量要有较大幅度的提高,必须着眼于栽培技术的进一步改革与提高。据笔者对杂交稻10余年的研究和
Over the years, the basic technical framework for high-yielding cultivation of hybrid mid-season rice in the western Sichuan plain is as follows: the six-three system is the dominant combination; the end of March-January is exposed to seedling raising Miao cut 1.5-1.7 million, the basic Miao 8-9 million, timely control pests. Under such technical structural conditions, the normal annual general mu production (mu, the same below) is about 500 kg, and the yield per unit area is hard to be further improved. In the current hybrid rice combinations without major changes in the conditions, the yield per unit area of rice to be more substantial increase, we must focus on the cultivation of technology to further the reform and improvement. According to the author of hybrid rice more than 10 years of research and
