1.多效唑 能控制大豆株高,缩短节间长度,增加茎粗,从而防止倒伏,并增加单株分枝数和荚、粒数,提高结实率和粒重,促进顶荚的形成,增产12％以上。在始花期后7天左右喷施,长势好的宜适当提早在始花前施用。667平方米用15％多蚊唑可湿性粉剂50～100克,对水50千克稀释后均匀喷施在大豆叶片的正反面,不重喷也不漏喷。无限结荚型品种浓度可稍高些,有限结荚型品种浓度宜低些;长势好的
1. Paclobutrazol can control soybean plant height, shorten the internode length, increase the stem diameter, thus preventing the lodging, and increase the number of branches and pods per plant, increase the seed setting rate and grain weight, promote the formation of the top pod, and increase the yield 12 %the above. Spraying about 7 days after the initial flowering, good growth should be appropriate to apply early before the beginning of flowering. 667 square meters with 15% multi-mosquito-azole WP 50 to 100 grams, 50 kg of water diluted evenly sprayed on the front and back of the soybean leaves, do not re-spray nor spray leakage. Unlimited pod-type varieties can be slightly higher concentration, limited pod-type varieties should be lower concentration; good growth
