1995~ 1999年对我州主栽籼型杂交水稻的代表性组合 ,从高产攻关入手 ,研究其获得高产的群体结构指标 ,高产栽培不同生育时期的形态指标 ,不同产量层次的施肥水平。对各关键措施的最佳选择作出了结论 ,提出了籼型杂交水稻高产栽培应坚持旺根、壮苗、早发、适群体、全程稳健生长的栽培法。并按不同海拔高度、土壤肥力、气候条件等 ,组装配套成单产 10 .5~ 12 .0 ,12 .0~ 13 .5 ,13 .5t/hm2 以上 3个产量层次的高产栽培技术。在州内 9个县市累计示范验证 3 193 8.4 6hm2 ,平均比对照增产 12 .5 7%。
From 1995 to 1999, the representative combinations of indica hybrid rice planted in our province were studied, starting with the research of high yield, studying the population structure index of high yield, the morphological index of different growth stages of high yield cultivation and the fertilization level of different yield levels. The conclusion is reached on the best choice of the key measures. The cultivation method of high yielding cultivation of indica hybrid rice should be rooted, strong seedling, early seedling, suitable group, and stable growth throughout the whole process. According to different altitudes, soil fertility, climatic conditions, etc., they were assembled into three high-yielding cultivation techniques with a yield of 10.5 ~ 12.0, 12.0 ~ 13.5, 13.5t / hm2. In 9 counties and counties in the state, a total of 3,193.84,6hm2 of demonstrations were verified, with an average increase of 12.57% over the control.
