1984年,根据杂交中稻的生理特性及四川盆地低光值、小温差、高湿度等生态特点,提出了“稳定穗数,主攻穗重”的设想,并试验形成了“稳促攻”超高产栽培新模式,包括地膜中苗,宽行双株,W调氮法,停滞期施氮等组装配套技术.运用这套技术,在荣县10万余亩稻田上连续6年亩产650公斤.1989年在32.67万亩推广部分技术,平均亩产增加50公斤.新模式还有利于再生稻的高产栽培. In 1984, based on the physiological characteristics of hybrid rice and its ecological characteristics such as low light value, small temperature difference and high humidity in Sichuan Basin, the idea of ​​“stable spike number and main spike weight” was put forward. The new cultivation model includes the Miaochu Miao, Kuanzhang double strain, W-N method, the stagnant nitrogen and other assembly and supporting techniques.Using this technology, in Rong County more than 100,000 acres of paddy fields for 6 consecutive years 650 kg per mu .1989 In 32.67 million mu to promote some of the technology, an average increase of 50 kg per mu. The new model is also conducive to high-yielding ratoon cultivation.
