地处塞外的承德地区,年平均气温只有7.5℃,降水500毫米上下,基本上是一年一作的杂粮区,产量长期处于低而不稳的状态。八十年代开始在滦河流域扩种水稻,栽培技术也逐步提高。1987年开始推行水稻规范化高产栽培技术,取得了显著效果。1990年有15万亩水稻平均亩产485公斤,其中5.5万亩平均亩产达到605公斤。其主要配套技术措施是:①因地制宜,选用良种;②作好种子处理,提高发芽势;③旱育稀植,培育壮秧;④精细整地,配方施足底肥;⑤适期插秧,确保插秧质量;⑥加强田间管理,确保丰产丰收。
Located in the outskirts of Chengde area, the annual average temperature of only 7.5 ℃, rainfall of 500 mm up and down, basically a year for the miscellaneous grain area, the output in a long period of low and unstable state. In the eighties began to expand rice in the Luan River Basin, cultivation techniques also gradually increased. Since 1987, the standardization and high-yield cultivation of rice has been implemented and remarkable results have been achieved. In 1990 there were 15 million mu of rice yielding an average of 485 kilograms per mu, of which 55,000 mu average yield reached 605 kilograms. The main supporting technical measures are: ① according to local conditions, the selection of fine varieties; ② make seed treatment to improve germination potential; ③ dry and sparse plants, nurturing strong seedlings; ④ fine preparation, the formula to plant foot fertilizer; ⑤ appropriate transplanting to ensure the quality of transplanting ; ⑥ strengthen field management, to ensure high yield harvest.
