我省杂交水稻繁殖制种产量一般偏低,1978年全省繁殖制种面积达66万余亩,平均亩产仅51斤,1979年繁殖制种产量虽略高于上年,但仍低于邻近兄弟省。如1978年江苏省制种面积27万余亩,平均每亩118.2斤,有42个县市亩产超过150斤,其中丹阳县万亩制种田平均亩产185.1斤,并出现了亩产超过400斤的高产田块。同年,福建省制种33万亩,亩产92斤。浙江省统计的10万亩制种田,平均亩产84.7斤。
The yield of hybrid rice breeding in our province is generally low. In 1978, the area of seed production in the province reached more than 660,000 mu with an average yield of 51 pounds per mu. Although the yield of breeding seed in 1979 was slightly higher than that of the previous year, it was still below Near the brotherhood. For example, in 1978, the seed production area in Jiangsu Province was more than 27,000 mu, with an average of 118.2 kilograms per mu. There were 42 counties and mounds producing more than 150 kilograms per mu, of which 185.1 kilograms were cultivated per mu in Danyang County and an average output of more than 400 mu Kg of high yield plots. In the same year, 33 million mu of seed were planted in Fujian Province, yielding 92 kg of mu. Statistics of Zhejiang Province 100,000 acres of farming system, the average yield of 84.7 kg.
