在毛主席革命路线指引下,我们提出了一个远大的选育种目标,希望选育一个品种可以在两造种植获得2400斤的亩产量,叫做“一种二造三超纲”。为达到这一目标,我们制订了“三、三、一”的设想,即每亩有效穗30万,千粒重30克,平均每穗结实100粒,也就是要培育穗大、粒重的多穗型品种。大和小,轻和重,多和少,都是矛盾的,能不能统一起来呢?马克思主义的哲学认为,对立统一规律是宇宙的根本规律。在一定条件下,矛盾的东西能够统一起来,又能够互相转化,大、多、重也应当能够结合在一起,因而“三、三、一”的设想是可能实现的。具体途径是利用早、晚造品种进行多亲系杂交,解决4个方面的问题:①前期要矮生丛化,分蘗多,后期生长较快,这样才能容纳较 Guided by Chairman Mao’s revolutionary line, we have proposed a lofty goal of breeding and breeding. We hope that breeding one species will yield 2,400 kilograms of mu per mu of land for two crops and is called “one type and two types and three supervisions.” In order to achieve this goal, we formulated the concept of “three, three and one”, that is, 300,000 effective spikes per acre and 30g average grain weights, with an average of 100 grains per spike. That is, we should cultivate large panicles Type Large and small, light and heavy, more and less, are contradictory, can we unify? Marxist philosophy that the law of unity of opposites is the fundamental law of the universe. Under certain conditions, the contradictory things can be uniformed and can be transformed into each other. The big, the big, and the heavy should also be able to be combined. Therefore, the concept of “three, three and one” can be realized. The specific approach is to use early and late varieties of multi-line hybrids to solve the problem of four aspects: ① premature dwarf plexus, tiller and more late growth faster, so as to accommodate more
