内蒙古锡林浩特市水浇地青贮玉米施肥指标体系的建立

Establishment of Fertilization Index System for Silage Maize on Irrigated Land in Xilinhot of Inner Mongolia

青贮玉米是饲养牲畜的优质饲料,能够为畜牧业养殖提供饲料保障。在内蒙古锡林浩特市3个具备水浇地条件的饲草料基地上种植青贮玉米品种——"长城9904",并采用测土配方施肥技术,选择高、中、低肥力水平的地块进行"3414"肥料肥效试验,同时对试验结果进行了分析和研究。该试验初步制定了锡林浩特市水浇地青贮玉米土壤养分丰缺指标体系,旨在为该市青贮玉米种植过程中科学、合理地施肥提供依据。

Silage corn is a high-quality feed for livestock raising and provides forage guarantee for animal husbandry.In this study,a silage maize variety of"Great Wall 9904"were planted in three forage production bases with irrigation condition in Xilinhot of Inner Mongolia;the"3414"fertilizer efficiency test was carried out by using the technology of soil testing formula fertilization in plots with high,middle and low fertility;the results were subsequently analyzed and studied.The index system of soil nutrient abundance and deficiency for silage maize planting on irrigated land in Xilinhot City was preliminarily determined,which provides a basis for scientific and rational fertilization in silage maize planting in this city.
