农业生产上一般所说的“良种”,应该包括优良品种和优良种子两个方面,即既是优良品种,又是质量极为良好的种子,两者结合起来,才是真正的良种。没有优良品种,良种的增产作用固然无从谈起;但是,只有优良品种,而没有高质量的种子,播种后就会出苗不全、不齐、不壮,容易发病,很难得到好收成。有的农民花了很多钱买了“良种”,却没有增产,很主要的一个原因就是没有全面认识“良种”的双重含义。

Generally speaking, “good seed” in agricultural production should include both fine varieties and fine seeds, that is, both excellent varieties and extremely good seeds of quality. When the two are combined, they are genuine varieties. There is no good varieties, the role of improved seed production although no mention; but, only good varieties, without high-quality seeds, after sowing will be incomplete, missing, not strong, prone to disease, it is difficult to get good harvest. Some peasants have spent a lot of money on “thoroughbreds” but have not increased their production. One of the main reasons for this is that they do not have a full understanding of the dual meaning of “thoroughbreds.”
