摘　　要：为了研究新型植物生长调节剂调环酸钙在直播稻上的应用效果,本研究设计了调环酸钙25％悬浮剂在直播稻武运粳8号上的田间试验,用来了解其对直播稻的抗倒伏性状和产量性状的影响.试验结果表明：在直播稻武运粳8号的分蘖期使用调环酸钙25％悬浮剂12～15g/667m2均能够显著降低水稻的株高,缩短茎基部节间长度,提高水稻的抗倒伏能力,同时也能显著提高水稻产量.To make researches on the application of prohexadione calcium 25％ suspension concentrate （SC） on direct seeding rice,the field trials of prohexadione calciurn 25％ SC on the transplanting rice and direct seeding rice were conducted.The results showed that this product could reduce rice height significantly,shorten stem basal intemode length,improve loding resistance and increase the yield of rice when used at the tillering stage with the application dosage of 12-15g product/667m2.
