Abstract: In order to offer practical references for resistant and high yield cultivation of mechanicaltransplanting rice, we used‘Nanjing 9108’as the experimental material and set different treatments by spraying 1.5 L/hm² Jingfeng, 60 g/hm² Bihu, 675 g/hm² Aizhuangfeng, 750 g/hm² potassium dihydrogen phosphate, 15 g/hm² gibberellic acid to study the effects of these biochemical reagents on the rice lodging resistance, plant types and growth period of blanket seedling mechanical- transplanting and nutrition bowl mechanical-transplanting. The results showed that the heading period was delayed one day and prolonged one day by using Jingfeng and gibberellic acid respectively. Gibberellic acid could significantly increase plant height, internodes length below the ear and height of gravity center, which were easy to cause the lodging. Aizhuangfeng, Bihu and potassium dihydrogen phosphate did not affect the heading period, they improved the plant lodging resistance ability by means of increasing basal internode filling and reducing height of gravity center. All reagents had no effect on mechanical- transplanting rice’ s whole growth period, ear length and sword leaf sheath length. The mature date of nutrition bowl mechanical-transplanting rice was two days later than that of blanket seedling mechanical- transplanting rice, which was conducive to grain filling and cultivating strong stalk and large spike by making full use of temperature and light resources. Bowl mechanical- transplanting rice tended to achieve stable high yield, and some biochemical reagents such as Aizhuangfeng, Bihu and potassium dihydrogen phosphate could effectively alleviate adverse impact from the abnormal climate, so it should be applied more widely and quickly in practical production.
