Effect of sowing time and seedling density on yield of Teyou 103

摘要: 采用二因子随机区组设计,在早、晚两季探讨不同播期与苗数对杂交水稻新品种特优103产量构成因素的影响,结果表明:播种期与苗数的变化主要引起穗粒数和穗数的变化。通过适宜的播期与适宜的苗数,在足够穗数的前提下,可以发挥特优103的大穗优势,提高其增产潜力。特优103在闽南作早、晚季高产栽培试验,在中肥水平条件下,早季2月中旬,晚季7月中旬初播种,每公顷基本苗插65万苗左右,才能获得较高的产量。Abstract: Effect of sowing time and seedling density on yield of the rice,Teyou103,in early and late seasons was studied.The result showed that sowing time and seedling density affected mainly the spike number and grains per spike.Thus,with moderate fertilization,Teyou 103 could be sowed in mid-February for the early crop and in mid-July for the late crop at a seedling density of 650,000 per hm2 in southern Fujian for the highest possible yield.
