今年我省计划种植双季稻1,200多万亩,比1958年增加近4倍,约占稻田总面积的35%以上。生产实践证明:种植双季稻能显著增产,一般比中稻增产30—60%,比一季晚稻增产20—50%,有的增产更高。因此,种好双季稻是我省当前发展农业生产增产粮食和改善人民生活的重要课题。 但是,晚稻的产量低而极不稳定。1956年平均亩产300斤,57年只有200—250斤,去年也还不够理想。 晚稻低产的原因,除了秋旱、肥料不足和螟害等不利因素外,主要是对品种的特性及其与外界环
This year, our province plans to plant more than 12 million mu of double-crop rice, nearly four times more than in 1958, accounting for more than 35% of the total paddy field area. Production practice has proved that planting double cropping rice can significantly increase production, generally 30-60% more yield than middle rice, 20-50% more yield than late rice in the first season, and some increase more. Therefore, planting double-cropping rice is an important issue for our province to develop agricultural production and increase people’s livelihood. However, the yield of late rice is low and very unstable. In 1956, an average of 300 kg of mu was produced, only 200-250 kg in 57 years. Last year, it was still not quite satisfactory. The reason for low yield of late rice, in addition to autumn drought, fertilizer shortage and other adverse factors such as stem borer, the main characteristics of the variety and the outer ring
