提高单产和增加复种是我省农业再上新台阶的两个有效途径。由于四川目前主要粮食作物具突破性的新品种较缺乏,继续提高单产难度较大。而四川盆地温光资源虽三季不足如两季有余,因此,开发晚秋作物的问题为农业战线所瞩目。目前对再生稻、秋菜、秋薯、秋玉米等秋作物的开发较有成效。我们从1981年起,每年均结合育种对秋大豆种植问题进行了一些探索,试抛砖以引玉: 一、大豆是粮食作物(相对薯类来说是“硬粮”),是油料作物,更是营养作物,并能增加 Raising yields and increasing re-cropping are two effective ways for agriculture in our province to reach a new level. Due to the lack of groundbreaking new breeds of major food crops in Sichuan, it is still more difficult to continue to raise yields. The Wenchuan resources in Sichuan Basin, although lacking in three seasons, such as more than two seasons, the development of crops in late autumn is the focus of the agricultural front. At present, the development of autumn crops such as ratoon rice, autumn vegetables, autumn potato and autumn corn is more effective. Since 1981, we have explored the issue of autumn soybean cultivation in combination with breeding every year. Trying to throw bricks to attract attention: First, soybean is a food crop (“hard grain” relative to potato) and is an oilseed crop. More nutritious crops, and can increase
