Abstract

Abstract: Taking wheat Yumai158 as the research object,the differences in yield and population dynamic characteristics under different sowing rates and spraying amount of paclobutrazol treatments were analyzed.The results showed that under different treatment,Yumai158 had average spike-bearing tiller rate,stable thousand-grain weight,and more grains per spike.The best sowing rate was112.5~150.0 kg/hm²,and the best dosage was600~1200 g/hm² of15% paclobutrazol powder.

Key words: wheat, Yumai 158, sowing amount, paclobutrazole
