摘要
1988～1989年在我省不同海拔地区,对不同品种、不同育秧方式的水稻,用100ppm多效唑浸种或300ppm多效唑苗期喷雾,均能控长促蘖,提高秧苗素质,增加有效穗数,平均比对照增产5.6～7.9％。不同育秧方式均以3叶1心期施药效果最好,两球育秧于1叶1心期在秧棚内施药经济效益高。
In the areas with different elevation of Guizhou Province, the testing results of treatments of soaking the seeds in 100ppm paclobutrazol (M ET) or spraying the seedlings of different nursery patterns with 300ppm(ME T) paclobutrazol to defferent rice varieties show that the MET can control the growth,and promote the tillering of rice plant,enhance the quality of the rice seedlings,increase the effective ear number and increase the yield by 5.6 -7.9% compared with check, 'When the rice seedlings of different nursery patterns reach the Stage of three Spreaded leaves and heart leaf,the effect of MET application is the best. To the two-stage raising seedlings the higher economice benefit of MET application can be achieved as treated with MET at the stage of 1 spreaded leaf and 1 heart leaf in the seedling shed.
