水稻控蘖增粒高产栽培新技术,是当前水稻栽培技术上的一项重大创举,也是发展稻田耕作制度的良好动力。慈利县有稻田25 330ha,海拔200m以下地区,以双季稻为主;200m以上高海拔地区,稻田只种一季。70年代开始试探稻稻油或稻油的新耕作制度。由于栽培技术不配套,产量产值虽有所增加,但耕作制度中矛盾比较突出,导致新 Paddy tillering and high-yielding cultivation of new technology is currently a major innovation in rice cultivation technology, but also a good driving force for the development of rice cultivation system. There are 25 330ha paddy fields in Cili County and 200m above sea level, with double-season rice as the mainstay. In the high-altitude areas above 200m, paddy fields are only one season. In the 1970s, it began to test the new farming system of rice or rice oil. Due to the lack of supporting cultivation techniques, although the output and output value have increased, the contradictions in the farming system have become more prominent, resulting in a new
