花培汕优63是我所用花培提纯更新不育系珍汕97A做母本、明恢63作父本配制而成的复壮组合,1985年在本所试种,1986年在我省四市七县三十多个基点示范种植,面积达1000多亩,一般亩产都在550公斤以上,比常规汕优63亩增稻谷50公斤左右,增产幅度达8～10％。其中一块30多亩的示范方平均亩产645公斤,高产田块达670公斤。由于该组合纯度高,优势强,稳产性好,增产潜力大,符合省工节能和高产优质的要求,深受群众欢迎。现在该组合已扩大到苏、皖、鄂、川、湘、黔等省,预计1987年种植面积将近100万亩。现将该组合的特征特性、各生育阶段的生态指标及栽培技术要点介绍于下,供各地参考应用。
Flower Pei-Shan 63 is my use of flowers to purify the updated sterile line Zhenshan 97A to do the mother, Ming Hui 63 father made from the combination of rejuvenation, 1985 in our stock, in 1986 in four provinces in our province Seven counties more than thirty basis point demonstration planting area of 1000 mu, generally more than 550 kg per mu, than the conventional Shanyou 63 acres of paddy by about 50 kg, an increase of 8 to 10%. One of the demonstration plots of 30 mu has an average yield of 645 kg per mu and 670 kg of high-yield plots. As the combination of high purity, superiority, good stability, good yield potential, in line with the provincial energy-saving and high-yielding quality requirements, welcomed by the masses. Now the combination has been expanded to Jiangsu, Anhui, Hubei, Sichuan, Hunan, Guizhou and other provinces, is expected to 1987 planting nearly 100 acres. Now the characteristics of the combination of the various stages of the ecological indicators and cultivation techniques introduced below, for reference and application around.
