摘要

Topic Be able to actualize the coating whose falling off of the iron powder is little not only seeding process regarding transport process, the secondary materials which at the same time are beneficial to the growth of the seed the seed which was covered with the iron powder for secondary materials content seed coating, the iron powder for secondary materials adhesion seed coating, the alloy steel powder for seed coating and the iron powder for secondary materials content seed coating, the iron powder for secondary materials adhesion seed coating and the alloy steel powder for seeding child coating which in growth of the seed can make the seed come in contact with desirable feature is obtained. SolutionsThe iron powder for secondary materials content seed coating which relates to this invention 0.01 - 100 mass sections contains the secondary materials powder vis-a-vis the iron powder 100 mass section, as for the aforementioned iron powder, particle diameter mass ratio of the iron powder of 63 millimicrons or less 75% or less of 0% or more, at the same time, particle diameter exceeds 63 millimicrons and mass ratio of the iron powder of 150 millimicrons or less 100% or less of 25% or more, mass ratio of the iron powder where at the same time particle diameter exceeds 150 millimicrons is 50% or less of 0% or more, it features that mean particle diameter of the aforementioned secondary materials powder is 45 millimicrons or lessIt is the thing.
