江苏省泰州市红旗良种场从1978年开始杂交水稻制种,常年保持在700hm~2,农忙季节雇请外来劳力栽母本,工价高,栽插密度难以保证,不易高产。为提高制种产量,我们逐步探索出以母本水直播为中心的综合配套高产栽培技术。本文以汕优63制种为例,对该技术体系作一总结。 The red flag seed farm in Taizhou City, Jiangsu Province, started hybrid rice seed production in 1978 and remained at 700hm ~ 2 for a long time. During the busy season, foreign laborers were hired to plant the original copy of their parents. The planting price was high and planting density was hard to guarantee. In order to increase the seed production, we have gradually explored a comprehensive high-yielding cultivation technique centering on mother-seed water. In this paper, Shanyou 63 seed production as an example, a summary of the technology system.
