1983年我们在长丰县稻麦良种场和朱集乡朱集村进行杂交水稻制种联产技术承包,共连片制种汕优6号293亩,获得了较好的收成.朱集村两片102.1亩,平均亩产185斤;稻麦原种场一片191亩,平均亩产208斤,其中高产田20亩,亩产达300斤.这两地制种的平均单产,超过同地1982年制种亩产十几斤的十几倍,也超过长丰县近几年的制种产量水平,高产田块接近或达到制种产量的先进水平.为了总结杂交制种的经验,不断提高制种产量水平,我们在制种过程中,采用了较为合理的栽培技术措施,并对父母本的生育特性进行了认真系统的观察记载.同时对当前持有争议的一些问题,在部分田块进行了初步探讨性的试验.
In 1983, we carried out the hybrid rice seed production technology contract in Changmao County Rice and Wheat Farm and Zhuji Township Zhuji Village, with a total yield of 293 acres of Shanyou 6, obtaining better harvest. The average yield per mu is 185 hectares, and the average mu yield is 185 kg. The original rice and wheat farm is 191 mu with an average yield of 208 kg, of which 20 mu is high yield farmland and the yield per mu is 300 kg. The annual seed production more than ten kilograms of dozens of times, but also more than Changfeng County in recent years, the level of seed production, high yield plots close to or reach the advanced level of seed production.In order to summarize the experience of hybrid seed production, continuous improvement system In the process of seed production, we adopted more reasonable cultivation techniques and measures, and carefully observed and recorded the reproductive characteristics of the parents.At the same time, some of the current controversial issues were carried out in some plots A preliminary exploratory test.
