金华县是浙江省主要内陆产棉区之一,年种植棉花5万亩左右,约占全县耕地面积的1/10。多年来,本地棉区的耕作方式素以小麦套作棉花。由于棉区人均占有耕地仅0.92亩,粮棉争地和粮经争地矛盾较为突出,为解决这一矛盾,我们在棉区广泛调查耕作方式的基础上,于1987～1988年设计了4种新的耕作方式的模式,进行了研究和探讨,现报道如下。设计和方法1.试验设计本试验在我县重点产棉区的罗埠区下章农试站进行,土壤肥力中上,试验分5个处理:①小麦+大麦=棉花,即2行小麦间作1行大麦,大麦收后套栽棉花;②大麦——棉花,即大麦(横条播、播
Jinhua County is one of the main inland cotton-producing areas in Zhejiang Province. It plans to plant about 50,000 acres of cotton annually, accounting for about 1/10 of the total arable land in the county. Over the years, the farming methods in the local cotton area have been wheat-encased cotton. As the per capita arable land in the cotton area is only 0.92 mu, the contradiction between the land for grain and cotton and the land for food and agriculture is prominent. To solve this contradiction, on the basis of extensively investigating the farming methods in the cotton area, 4 kinds The new mode of cultivation mode, conducted a study and discussion, are reported below. DESIGN AND METHOD 1. Experimental Design The experiment was carried out in the Nongzhuang Station of the Luohu District in key cotton-producing areas in our county. Soil fertility was tested in five treatments: ① wheat + barley = cotton, ie, wheat intercropping in 2 rows 1 row of barley, barley after the set of cotton plants; ② barley - cotton, that is, barley (horizontal sowing, sowing
