积极探索小麦高产更高产的途径,是川西平原小麦生产上面临的迫切问题。1978年,我们在《川西平原小麦高产途径的探讨》一文中提出:“增苗增穗是低产变高产的有效途径”,“降低基本苗,较多依靠分蘖成穗,有利于高产更高产”。(见《四川农业科技》1978年第3期)这一看法提出后,引起了广泛注意,不少单位作了试验示范,取得了肯定的结果。为了更深入地认识这一问题,去秋以来我们采用不同类型品种继续进行试验,结果进一步证明:从调整群体出发,降低基本苗,较多依靠分叶成穗,确实是川西平原小麦高产更高产的可靠途径。现将试验情况简报如下:
Actively exploring the ways for higher yield and higher yield of wheat is an urgent problem facing wheat production in the western Sichuan plain. In 1978, we pointed out in the article “A Discussion on the High Yield Ways of Wheat in the Western Sichuan Plain.” “Increasing seedling number and increasing ear yield are effective ways for low yield and high yield.” “Reducing basic seedlings and relying more on tillers and spikes is conducive to higher yield and higher yield” . (See “Sichuan Agricultural Science and Technology”, 1978, No. 3) After this view was put forward, it attracted widespread attention. Many units made experimental demonstrations and obtained affirmative results. In order to understand this issue more deeply, we have been experimenting with different types of varieties since the fall of autumn. The results further prove that starting from adjusting the population, reducing basic seedlings and relying more on leaf-splitting into spikes are indeed higher-yielding and more-yielding wheat in the western Sichuan plain Reliable way. Now briefing the test as follows:
