| 摘 要： | 以８０ｐｐｍ“９２６植物生长调节剂对水稻浸种，可提高发芽势４．６％，增加次生根数６．２％，次生根长增加２．０％，以１５０ｐｐｍ浓度浸种，则有抑制作用产生。小区试验表明，以８０ｐｐｍ浓度浸种，增产率为２．３％。以同样浓度于分蘖期、孕穗期一次给药，可分别提高成穗率１２．３７％和１３．８３％，增产率分别为３．７％和２．２％。．

| Abstract: | The results of the trial has shown:if sloe is soaked by 80ppm- 926,the vigour germinating is in creased by 4. 6%, the amount and length of secodang soots is increased by 6. 2% and 2. 1%. On the contrary, if nice is soaked by 150ppm,it will retard the progress of growth.The result of small area trial of rice planting bac shown:if nice is soaked by 80ppm-926,the rate of effective ears is inceased by 6. 33,the output is increased,by 2. 3%. Using same concentration in tillering stage and boot stage,the effective rate of ears is increased by 12. 3% and 13. 83%. nespectively, the output is increased by 3. 7% and 2. 2% nespetively. |
