于1986年,开展了河北省冀东稻区水稻稳产高产规范化栽培技术研究,利用二次正交旋转组合设计的方法,通过两年的田间试验,建立了适合河北省滨海稻区、山前平原井灌区和山前平原渠灌区三种不同生态条件下的水稻生产模型,结合品种、耕作、植保、水肥管理等模式,初 In 1986, the research on standardized cultivation techniques of high and stable yield and high yield of rice in Jidong rice paddy area of ​​Hebei Province was carried out. By means of quadratic orthogonal rotation combination design, two years of field experiments were conducted to establish a suitable rice cultivation area suitable for Hebei coastal rice paddy, Well irrigation and piedmont irrigation district under three different ecological conditions of rice production model, combined with varieties, farming, plant protection, water and fertilizer management model, the early
