一 棉花密度 合理密植是解放后十年来,保证棉花增产的重要措施之一。这在历年群众的生产实践和试验研究中,都得到了充分的证明。在推行合理密植过程中,全国范围内棉花密度总的趋势是在不断增加,但因为不同年份,不同地区的条件有差别,对密植的具体密度的运用认识还不完全一致,有时增加,有时又减低。一九五八年棉花生产大跃进,密植对获得空前大丰收起到了显著作用。但在一九五九年继续 A close density of cotton density close ten years after liberation, one of the important measures to ensure cotton yield. This has been fully proved in the production practices and experimental studies conducted by the masses over the years. In the process of implementing reasonable planting density, the overall trend of cotton density in the whole country is increasing constantly. However, the conditions of different years and regions are different, and the understanding of the use of specific planting density is not exactly the same, sometimes increasing and sometimes reduce. The great leap forward of cotton production in 1958 and the close planting played a significant role in the unprecedented harvest. But continued in 1959
