一、探讨的中心问题为了实现沈阳市水稻“双高一优”生产,于1986年～1987年探讨水稻高产高效栽培模式.主要栽培技术措施是培育旱壮秧(旱育稀播)、合理稀植(少插秧)、肥水平稳促进(平稳管理)等,简称“旱稀少平”栽培.因为沈阳低温寡照年份偏多,如果种植晚熟品种就容易遭灾减产,所以首先探讨了中熟品种的栽培模式,通过这种栽培易使水稻生育期有所延长,获得年份间稳产效果.优质一是指品种的米质优良,二是指用栽培措施提高稻谷质量.决定优质的主导因素是品种的米质,故选 First, to explore the central issue In order to achieve Shenyang city rice “Shuanggaoyiyou ” production, in 1986 to 1987 to explore rice high yield and efficient cultivation mode. The main cultivation techniques and measures are to cultivate dry seedlings (dry nursery broadcasts) Reasonably thin planting (less transplanting rice), smooth fertilizer (smooth management), etc., referred to as “drought sparse flat ” cultivation.Since Shenyang low temperature sunshine years is too much, if the cultivation of late-maturing varieties are vulnerable to disaster reduction, so the first to explore the Cultivation of cooked varieties through this easy to make rice growth period has been extended to obtain stable yield between years of quality one refers to the good varieties of rice, and second refers to the use of cultivation measures to improve the quality of rice. Decide the dominant factor of high quality Is the quality of the species, so choose
