随着种子的更新换代和农业科技的突飞猛进,棉花获得高产已不再是难事,但从经济学角度来看,很多农户难以做到高产又高效这一点。笔者对湖北棉花高产品种的非常了解,并曾经做过棉花高产与密度、施肥关系的试验,初步提出棉花高产高效栽培技术如下,以供广大农民参考。 With the upgrading of seeds and the rapid advancement of agricultural science and technology, it is no longer difficult for cotton to obtain high yields, but many economists find it hard to achieve high yield and efficiency from an economic point of view. The author knows very well about the high-yielding varieties of cotton in Hubei Province and has done experiments on the relations between high-yielding cotton and high-density cotton and fertilizing. The paper puts forward the following high-yield and high-efficient cotton cultivation techniques for the reference of farmers.
