摘要
"劲丰"是利用维生素与微量元素为主体复配研制的稻麦增产抗倒营养剂,试验结果表明:"劲丰"对水稻植株性状具有明显的调控作用,主要表现为改善水稻基部茎秆组织结构,增大膨压与抗折力,缩短穗下节间长度,降低重心,极大地提高水稻抗倒伏性;同时具有显著的增产效果,增产主要体现在增加穗粒数和千粒重;劲丰的最佳喷施时期为水稻破口期,最佳使用量为120ml/667m2。
＂Jingfeng＂ is a kind of yield-increase and lodging-resistance nutrition agent for rice and wheat.The experiment results show that ＂Jingfeng＂ has the function of controlling plant characters obviously,which mainly represents at improving stem-basal tissue structure of rice,increasing breaking-resistance,shortening inter-node length below ear to increasing its lodging-resistance and has obvious yield-increase effect.The yield-increase embodies at grain/ear quantilty and thousand-grain weight increase,the best period for spraying ＂Jingfeng＂ is the rice ear opening stage with 120ml/mu application.
