稀土无论叶面喷施或拌种 ,均具有一定的增产效果 ,叶面喷施增产幅度大于拌种。叶面喷施浓度以每公顷 90 0～ 112 5ml为宜 ,拌种浓度一般田块以 35～ 4 5ml拌 5kg种子为宜 ;2 5ml稀土拌 5kg种子+花针期喷施 112 5ml/hm2 增产效果最好 ,结荚期和苗期各喷 1次次之 ,花针期喷施 1次亦具有较好的增产效果 ;稀土对增加植株根瘤数量、提高单株叶面积和叶片光合能力以及改善花生籽仁品质亦有一定促进作用。
Rare earth regardless of foliar spray or seed dressing, have a certain effect of increasing yield, foliar spray yield greater than the seed dressing. Spraying foliar application rate per hectare 90 0 ~ 112 5ml is appropriate, the seedling concentration of general plots to 35 ~ 45ml mix 5kg seeds is appropriate; 2 5ml rare earth mix 5kg seeds + flower needle spraying 112 5ml / hm2 yield The best effect, the podding and seedling spraying each times followed by the flower needle spraying once also has a better yield; rare earth to increase the number of plant nodules, leaf area per plant and leaf photosynthetic capacity and improve Peanut seed quality also has some role in promoting.
