丽欧甜高粱(RIO)是一种糖源禾本科作物,随着人们对它的认识和本身价值的不断提高,目前已发展成一种主要的高产优质青饲料。我场于1984年从天津引种观察试种,试图探索丽欧甜高粱在本区自然条件下获得高产的规律性,为大面积推广提供栽培依据。一、试验方法试验在场科研站进行,土壤质地为壤质轻盐土,含盐量0.26%,pH值8.2,有机质1.234％,全氮0.085%,水解氮67ppm,全磷0.07%,有效磷31.3ppm,有效钾200ppm。前茬休闲地(种过西瓜)。试验地统一施底肥碳铵80斤,采用三因素、三水平设计方案进行,播期分4月16日、26日,5月6日三期,密度分4500株/亩、5500株/亩、6500株/亩
Liou Sweet Sorghum (RIO) is a saccharide source gramineous crop, with people’s understanding of it and its continuous improvement in value, has now developed into a major high-yielding quality green fodder. My field in 1984, introduced from Tianjin observation and trial, trying to explore Liou sweet sorghum in the region under the natural conditions of high yield regularity, provide a large area for the promotion of cultivation basis. First, the test method The test at the scientific research station, the soil texture of loamy saline soil, salt content 0.26%, pH 8.2, organic matter 1.234%, 0.085% of total nitrogen, 67ppm of hydrolyzed nitrogen, 0.07% of total phosphorus, available phosphorus 31.3ppm , Effective potassium 200ppm. Before crop leisure (watermelon). Test uniform ground fertilizer ammonium bicarbonate 80 pounds, using three factors, three levels of design, sowing date April 16, 26, May 6 three, density points 4500 / mu, 5500 plants / mu, 6500 plants / mu
