用早稻品种翻秋作双季晚稻种植(早翻早),是近几年来我场在发展一油(油菜)两稻三熟生产中,逐步摸索出解决品种搭配的一条较好的经验。这是因为早翻早能提早让茬,可以及时播种油菜,使三熟生产,熟熟主动,粮食和油料作物,年年增产。我场早翻早品种占双季晚稻的面积,已由1974年的2.12%扩大到1976年的8.33%,计划再扩大到10—15%。一、有哪些好处?(一)短龄密播,节省秧田:我场双季稻品种搭配,一向是早籼晚粳。粳稻的播种量是每亩150—200斤,秧田期30—50天;采用早翻早时可以短龄密播,
Using early rice varieties to turn autumn into double-season late rice planting (as early as early morning), in recent years, I field in the development of a two-rice (rape) rice three production, and gradually find a better solution to match the variety of experience. This is because the earliest early early crop stubble, you can sow the rape timely, so that the three cooked production, cooked initiative, food and oil crops, annual increase. The area of early rice field that breeds early rice in late seasons has expanded from 2.12% in 1974 to 8.33% in 1976 and is expected to expand to 10-15%. First, what are the benefits? (A) close-sowing, save seedlings: My field double-crop varieties with rice, has always been indica late indica. The sowing rate of japonica rice is 150-200 kg per acre and the seedling period is 30-50 days;
