引言 花生是苏丹一种重要的经济作物,栽培面积为1.030,000公顷左右,其中80％位于苏丹西部的降雨区,年降雨量300—900毫米,20％在灌溉区,该区的产量占总产量的42％。 鉴于降雨的多少与分布,降雨区花生的产量是不稳定的(0.47—0.95吨/公顷)。在灌溉区很容易获得2.97吨/公顷的荚果产量。在实验的条件下,潜在产量可高达6.7吨/公顷。本文的目的系总结有关灌溉区取得最高产量相应的主要因素。
Introduction Peanut is an important cash crop in Sudan with cultivated area of about 1.030,000 hectares, of which 80% is in the rainfall area of western Sudan with an annual rainfall of 300-900 mm and 20% in the irrigated area, which accounts for a total of 42% of output. Peanut production in the rainfall area is not stable (0.47-0.95 t / ha) due to the amount and distribution of rainfall. Yields of 2.97 t / ha are easy to obtain in the irrigated area. Under experimental conditions, potential yields can be as high as 6.7 tonnes / ha. The purpose of this paper is to summarize the main factors relevant to achieving the highest yields in irrigated areas.
