我区南部自然条件优越,有利发展绿肥,但近年来,复种面积不断扩大,使绿肥种植受到限制,进一步加剧了用地养地的矛盾。为了不影响复种,又能培肥土壤,迅速提高单位面积产量,1977—79年我们采取大面积试验示范办法,研究了夏玉米间套短期绿肥的增产效果和相应的栽培技术措施,现将结果报告于后:一、基本情况试验田设在泾阳姚坊公社官道大队,渠井两灌,自然条件较好,生产水平较高。
The natural conditions in the southern part of our region are favorable for the development of green manure. However, in recent years, the area of multi-cropping has been continuously expanded, which has restricted the cultivation of green manure and further aggravated the contradiction of land use. In order not to affect the multiple cropping, but also fertilize the soil and rapidly increase yield per unit area, 1977-79 we take a large area demonstration experiment to study the summer maize sets of short-term green manure yield and corresponding cultivation techniques and measures, the results After the report: First, the basic situation Experimental field located in Jingyang Yao Square commune official Road Brigade, irrigation wells and irrigation, better natural conditions, a higher level of production.
