新事物的出现,总是最先被高瞻远瞩者所注目和实践,然后通过宣传、辐射,才能得到逐步普及。如何对待小麦播量问题,也将如是。 本刊于1989年第一期报道了小麦播量试验材料和发表了《盲目追求小麦大播量的做法应该休止》的评论文章后,不少农业技术人员反映:击中了当前小麦生产中的一个要害问题。一些生产单位积极而又慎重地进行了减少播量的尝试或进行不同播量比较试验。大量的结果表明,只要选好种,平整好土地和进行合理的施肥与浇水,减少播量是完全可行的,而且是夺取小麦高产的必由之路。 在评论文章发表的当年,一四八团即在3.3亩地上,用人工稀播,亩播量仅3kg,比该团常规播量减少21kg,获得平均单产339kg,不仅不低于当年全团小麦平均产量,反而略有提高。1990年该团扩大 The emergence of new things is always the first to be the attention of the far-sighted and the practice, and then through publicity, radiation, in order to get gradually popularized. How to deal with the issue of wheat sowing, will be the case. After publishing the commentary on wheat sowing test material and the publication of the article entitled “Blind pursuit of large seeding volume should be discontinued”, many agricultural technicians reported in the first issue of 1989 that they hit the current wheat production A crucial issue. Some production units actively and prudently carried out attempts to reduce sowing or sowing rates. A large number of results show that as long as a good choice of species, the formation of a good land and reasonable fertilization and watering, reducing sowing is entirely feasible, and is the only way to win the high yield of wheat. In the year when the commentary was published, the 148th Corps, ie, 3.3 acres of land, was planted with artificial sowing, with an acreage of only 3kg, which was 21kg lower than that of the regiment. The average yield of 339kg was not only lower than that of the entire regrouping of wheat Average output, but slightly increased. The regiment expanded in 1990
