随着农业生产的不断发展,上海郊区农村产业结构逐渐调整,农业劳动力开始转向工、副业,棉农要求有迟播、早熟、高产、省工、省本、简易栽培的新棉种,替代生长周期长、栽培技术繁杂、用工多的传统品种。为此,我们从1978年配制的杂交组合中选育出耐迟播、早熟的“沪农早棉”(3005)。 With the continuous development of agricultural production, the industrial structure of rural areas in Shanghai’s suburbs has been gradually adjusted, and the agricultural labor force has begun to shift to new jobs for workers, sideliners and farmers requiring late sowing, early maturing, high-yielding, labor-saving, provincial-level and simple cultivation, replacing the growth cycle Long, complicated cultivation techniques, labor and more traditional varieties. To this end, we selected from the hybrid combinations prepared in 1978 to delay sowing, early maturity, “Shanghai Morning Cotton” (3005).
