摘要： A seed-covering agent, which is used for covering a seed surface and which contains an iron powder and a binder, is specified in such a way that, in the above-described iron powder, the mass ratio of an iron powder having a particle size of 63 µm or less to a total mass of the iron powder is 0% or more and 75% or less, the mass ratio of an iron powder having a particle size of more than 63 µm and 150 µm or less to the total mass of the iron powder is 25% or more and 100% or less, and the mass ratio of an iron powder having a particle size of more than 150 µm to a total mass of the iron powder is 0% or more and 50% or less, and the average particle size of the above-described binder is 1 to 150 µm. Consequently, a cover with reduced falling of the iron powder in not only a seeding step, but also a transportation step can be realized.

摘要： The present disclosure relates to an iron-based prealloy powder having excellent strength and processability, and an iron-based alloy powder for powder metallurgy and a sinter-forged member using the same. The iron-based prealloy powder for powder metallurgy according to an embodiment of the present disclosure includes 0.5 to 5.0 wt% of Cu, 0.1 to 0.5 wt% of Mo, and a balance of Fe and other inevitable impurities. A Cu content (Cu%) and a Mo content (Mo%) satisfy the following Relational Equation (1): 0.3 × Cu% + 3 × Mo% ≤ 2 .7

摘要： In an iron powder for coating a seed, the mass percentage of an iron powder with a particle size of 63 µm or less is 0% to 75%, the mass percentage of an iron powder with a particle size of more than 63 µm to 150 µm is 25% to 100%, and the mass percentage of an iron powder with a particle size of more than 150 µm is 0% to 50%. This allows the iron powder to form a coating from which the iron powder is unlikely to drop during not only seeding but also transportation and also allows an iron powder-coated seed coated with the iron powder to be obtained. Furthermore, the following iron powder and rice seed can be obtained: an iron powder, unlikely to damage rice seeds and easy to handle, for coating a rice seed and an iron powder-coated rice seed coated with the iron powder.
摘要翻译：在用于涂覆种子的铁粉中，粒径为63μm以下的铁粉的质量百分比为0〜75％，粒径大于63μm〜150μm的铁粉的质量百分比 μm为25〜100％，粒径为150μm以上的铁粉的质量百分比为0〜50％。这使得铁粉形成一种涂层，铁粉不仅在接种期间不会下降，而且运输，并且还可以获得涂覆有铁粉的铁粉涂覆的种子。此外，可以获得以下铁粉和水稻种子：铁粉，不可能破坏水稻种子并且易于处理，用于涂覆水稻种子和涂有铁粉的铁粉包覆的水稻种子。
