一、棉花高垅栽培的提出与增产效果河北省成安县1956年遭受大水灾后,全县棉花亩产皮棉31.87斤,但有的棉田仍获得丰收。如西二祖中兴社11亩丰产棉花亩产皮棉154斤,落町5亩丰产棉花亩产皮棉128斤。经过深入调查研究,其丰产共同的原因是地势较高排水良好。另外在苗期观察到田埂和伏耕的墒脊上,出苗早生长旺。所有这些现象构成了对棉花在高处增产的认识,这是棉花高垅栽培的起点。在这一思想基
First, the proposed cultivation of cotton Gaojiu and yield increase Cheng’an County, Hebei Province suffered a flood in 1956, the county 31.87 pounds of cotton per mu, but some cotton fields are still bumper harvest. As the Second Zu Zun Zhiping 11 acres of high-yield cotton yield 154 pounds of cotton, 5 acres of high-yielding cotton Lushu yield 128 pounds of lint. After thorough investigation and study, the reason for its high yield is that high water drainage is good. In addition, observed in the seedling and field furrow furrow ridge, the emergence of early growth flourishing. All of these phenomena constitute a recognition of cotton production at high altitudes, which is the starting point for the cultivation of cotton cultivars. In this mindset
