北方农田立体种养模式土壤含水量变化规律研究

试验通过冬性黑麦草复种水稻、春性黑麦草复种水稻、春性黑麦草复种大豆、春性黑麦草复种玉米四种种植模式对水分利用情况研究,结果表明：不同种植模式下作物种类、种植时间不同,对土壤水分利用也不同.冬牧草复种水稻田块耗水量最大,米草鹅和豆草鹅居中,正常大田耗水量最少,因此提高复种指数,发展立体种植模式对水田是一种较好的模式,对旱田却进一步加剧了春旱,但如果能够解决播种和作物生长前期的干旱问题,几种复种模式还是有很大的可行性.

The Soil Moisture Changing on Three-Dimensional Mode of Planting

Under the different planting patterns, the types of crops the time of planting crops are different, it is also different to the soil moisture and water consumed. Winter grass multiple cropping water consumption is the biggest, Mi Caoe and the bean grass goose comes between, the normal big field water consumption are least. In order to enhances the duplicate kind of index, the development of three-dimensional ptanting pattern to the paddy field is a kind of good patterns, but it is actually intensified the spring drying to the dry farm land step. but it could solve earlier period arid question, several kinds of duplicate kind of modes have very big feasibility.
