1983～1989年,采用小区试验和大田示范相结合的方法,对兴化市内不同农业区大麦后移栽棉花(下称麦后棉)适宜密度范围、生长发育动态与季节进程优化同步指标及其高产栽培配套技术进行了研究.结果表明:(1)兴化四个农业区地面高程、土质类型和潜在肥力有差异,亩产皮棉100kg左右的高产棉田的密度范围也不相同,但在适宜的密度范围内,不同密度均可达到亩总铃7.2万个左右的高产指标,密度与亩总铃数呈极显著的曲线相关,各农业区相关系数分别为:0.7981、0.8317、0.8554、0.8550,依回归方程推导,各农业区适宜密度极差为700株左右;(2)高产棉花定型株高最佳值为 105～110cm,其主茎生长的理想动态为:盛蕾前、盛蕾～开花、开花～盛铃、盛铃后株高增长量各占最终株高的1/4;(3)实现生育进程和季节进程优化同步的中心环节是“蕾-铃-絮”对应“三集中”;(4)高产栽培的技术体系是壮苗、早发、稳长、不早衰。
From 1983 to 1989, using the method of plot experiment and field demonstration, the suitable density range, growth and development trend and season process synchronization index of cotton after transplanting of barley in different agricultural areas of Xinghua City The results showed that: (1) There were differences in ground surface elevation, soil type and potential fertility among the four agricultural areas in Xinghua, and the density range of high yielding cotton field with about 100 kg per mu lint was not the same, Density, the density can reach 72,000 mu of total yield of high yield indicators, the density and the total number of acres of bell was extremely significant curve correlation, the agricultural area correlation coefficients were: 0.7981,0.8317,0.8554,0.8550, According to the regression equation, the suitable density of each agricultural area is about 700. (2) The optimum height of high-yielding cotton is 105 ~ 110cm, the ideal dynamic of main stem growth is Shenglei, Shenglei ~ flowering , Flowering ~ ShengLing, ShengLing after plant height growth each accounted for 1/4 of the final plant height; (3) to achieve fertility process and seasonal process optimization synchronization center is “bud - bell - floc” corresponds to “three concentration” ; (4) high-yielding cultivation techniques System is strong seedlings, early onset, stable, not premature.
