资源县的中稻种植面积占水田总植面积的80.5％,总产占水稻的83.5％。种植高度分布:海拔450米以下约占15％;450—800米约占71％;800米以上约占14％。近年来该县中稻生产有了长足的进步。总产、单产分别是解放初的2倍、2.3倍。1974年以来,中稻平均单产比早稻约高130公斤/亩,比晚稻约高245公斤/亩。找出影响该县中稻产量的大田中稻生育期农业气象症结,对采取相应对策,夺取稳产高产,进而繁荣山区经济有重要的意义。
Resource County, rice planting area accounted for 80.5% of the total paddy field area, total output accounted for 83.5% of rice. Planting height distribution: 450 meters above sea level about 15%; 450-800 meters about 71%; 800 meters above about 14%. In recent years, the county has made considerable progress in middle-rice production. Total output, yield was 2 times the liberation early, 2.3 times. Since 1974, average yield of middle rice has been about 130 kg / mu higher than that of early rice and 245 kg / mu higher than that of late rice. Identifying the agro-meteorological symptoms of Mid-field rice growth period that affects the middle-grade rice production in this county is of great significance to taking appropriate measures to seize stable and high-yielding and thus prosper the mountainous economy.
