发展杂交水稻是提高粮食产量的重要途径;而提高制种产量、降低成本、满足用种需要,则又是发展杂交水稻和开发“吨粮“田”的先决条件。因此,进几年来吉水县对制种技术进行了研究和改进,使制种产量有一个新的突破。1985年以前,全县平均制种亩产在60公斤上下徘徊,1987年全县制种1000亩,平均亩产达130公斤,增长1.16倍;1988年全县制种1402亩,平均亩产达180公斤,是1985年单产的3倍。特别是新和乡夏制的汕优桂33和协优64等组合,连续两年丰收。198(?)年该乡集中连片制种305.7亩,
The development of hybrid rice is an important way to improve grain yield, while raising seed production and reducing costs to meet the need of planting seed are the prerequisites for developing hybrid rice and developing “tons of grain.” Therefore, The seed production technology has been studied and improved so that a new breakthrough in seed production.Every year 1985, the county average seed production per hectare hovering around 60 kg in 1987, the county seed production of 1,000 mu, the average yield per mu 130 kg, an increase of 1.16 times; in 1988 the county seed production 1402 acres, the average yield of 180 kilograms, three times the yield in 1985. Especially the new and rural summer system Shanyou Gui 33 and Xie You 64 combination, For two consecutive years of harvest .198 (?) Year the township 305.07 acres of contiguous seed production,
