富阳县南安公社,地处山区,全公社共4000亩连作稻田要留晚稻专用秧田500亩,早稻只能种植85%。为此,几年来,我们进行了一些试验研究,但倒种春和小苗带土移栽因受山区气候影响,把握性不大;早稻田套播因共生期长,晚稻秧苗素质差;旱地育秧的又因胡麻叶斑病重。所以,迄今为止,上述办法仅在很小面积上采用。1974年,我们从《科技简报》*得到启发,在早稻行间套播晚稻秧。全公社共有3个大队5个生产队搞了7.10亩套播试验。试 Nanan commune Fuyang County, is located in the mountains, the whole commune a total of 4,000 acres of continuous cropping rice to stay late rice 500 acres of special seedlings, early rice can only be planted 85%. Therefore, in the past few years, we conducted some experimental studies, but the seedlings with transplanting and seedling transplanting because of the impact of mountainous climate, the grasping sex is not big; the long-term symbiosis of early rice paddy resulted in poor quality of late rice seedlings; Because of flax leaf spot disease heavy. So far, the above approach has only been adopted on a very small area. In 1974, we got inspiration from the “Technology Briefing” * and planted late rice seedlings between early rice lines. The communes a total of three brigades 5 production teams engage in 7.10 acres of set-broadcast test. test
