杂交水稻制种是当前生产的薄弱环节,往往存在着制种产量不高不稳问题。为了摸索汕优6号制种的高产规律,研究高产栽培技术,提供科学依据,我们于1982年组织了全区7县1市11场、队进行夏季、秋季制种高产协作攻关试验。收获时经地、县、区三级种子干部分别到实地验收,11点总面积68.1亩,总产20922.3斤,平均亩产
Hybrid rice seed production is the current production of the weak links, there is often the problem of low seed production instability. In order to explore the high yielding rule of seed production in Shanyou 6 and to study high-yielding cultivation techniques and provide scientific basis, we organized 11 fields and 1 market in 7 districts and counties in 1982 and conducted joint and high-yield joint research trials in summer and autumn. Harvest by the prefecture, county, district three seed cadres to the field acceptance, 11 points a total area of 68.1 acres, a total of 20,922.3 kg, the average yield per mu
