丰宁满族自治县接坝深山区的苏家店乡,1989年试种水稻成功,至1993年已发展到2000多亩。由于采取了抗低温、促早熟为主体的综合配套栽培技术措施,在无霜期仅有105—110天,年降雨量450毫米的条件下,水稻平均亩产仍达到376.9公斤,其中苏家店村刘学诗、王荣江的1.2亩黑粳5号水稻,亩产分别高达768和759公斤。他们的这一成功经验,势将为高寒山区进一步调整种植结构,提高种田经济效益,促进高寒山区农业的进一步发展奠定基础。他们的主要栽培技术经验是:一、选用高产稳产、早熟、耐水肥、抗逆性强的“黑粳5号”为主栽品种,搭配“合江19”和“8112”。二、依据接坝深山区气候特点和生产条件,借鉴“旱育稀植”经验,推广过水薄膜旱育苗、早育、早插、合理稀植等栽培技术。
Fengning Manchu Autonomous County to connect dam deep mountain area Sujiadian Township, 1989 test rice success, to 1993 has grown to 2000 mu. As a result of low-temperature, promote early maturity as the mainstay of the integrated cultivation techniques and measures in the frost-free period of only 105-110 days, the annual rainfall of 450 mm under the conditions, the average rice yield still reached 376.9 kg, of which Sujiadian Village Liu Xue , Wang Rongjiang 1.2 acres of black japonica rice 5, respectively, up to 768 and 759 kg per mu. Their successful experience will set the stage for further adjustment of the planting structure in the alpine region, raising the economic benefits of farming and promoting the further development of agriculture in the alpine region. Their main cultivation technology experience is as follows: First, the selection of “high-yielding and stable, precocious, water-resistant, strong resistance” black japonica 5 “as the main varieties, with” Hejiang 19 “and” 8112 “. Second, according to the dam mountainous climatic characteristics and production conditions, drawing on ”nursery and thinning " experience, the promotion of water thin film dry nursery, early breeding, early plug, reasonable sparse planting techniques.
